50 Tools to Spy on Competitor Ads

Why watching competitor ads is worth the time

Somebody on your team is guessing right now. Guessing which hook will work, which angle is tired, which price point the market will actually accept. Ad spy tools replace that guess with a screenshot of what’s actually running, right now, paid for by someone with a bigger budget than yours.

That’s the whole pitch. You don’t copy the ad. You copy the signal, this creative has been live for six weeks, this landing page changed twice this month, this competitor just started running video where they used to run static images. Something worked. You’re just finding out what before you spend your own money confirming it.

Free.

That’s also roughly what most people think ad spying costs, because several major platforms now publish some version of a public ad library. Meta started it, Google followed, TikTok, LinkedIn, X, and Snapchat each added their own version to varying degrees. It’s a genuinely useful place to start. It is not, on its own, enough, and that gap is exactly where the other 44 tools on this list live.

There’s a second reason this matters more than it did five years ago. Ad platforms have gotten quieter about targeting data, spend figures, and audience breakdowns, partly from privacy regulation and partly from platforms simply deciding to hide it. The ads themselves are still public. The context around them, who’s seeing them, how much is being spent, how long a campaign has run, increasingly isn’t, unless a third-party tool goes and reconstructs it. That reconstruction work is most of what you’re paying for when you buy one of the tools below.

There’s also a timing advantage that gets underrated. Most categories have a handful of advertisers who genuinely test, they run three or four variants of a hook, kill the losers within days, and scale whatever survives. If you’re watching closely, you see the losing variants disappear and the winner keep running. That sequence, not the winning ad alone, tells you what the market actually responded to. A single screenshot of a currently-running ad tells you what survived. Watching the same advertiser over two or three weeks tells you what didn’t, which is arguably the more useful half of the lesson.

How this list was put together

Every tool below is active as of this writing. That matters more than it sounds, this category has a graveyard. iSpionage shut down in 2025. BrandTotal has gone quiet enough that its own listing pages contradict each other on whether it’s still operating, so it’s been left off this version of the list entirely rather than risk sending you to a dead product.

The list is grouped by what the tool is actually built to watch, not by some arbitrary ranking. A tool that’s brilliant for dropshipping Facebook ads is a bad fit for a B2B SaaS team tracking a competitor’s LinkedIn thought-leadership spend, and vice versa. Matching the tool to the job matters more than which one has the flashiest homepage.

A handful of entries here aren’t pure “ad spy” tools in the narrowest sense, Owler, BuiltWith, and Wappalyzer, for example, don’t show you a competitor’s actual ad creative. They’re included because they answer a question that sits right next to ad spying: what technology is this competitor running, who funds them, what’s their broader market position. If your research stops at “what does their ad look like,” skip that last group. Most serious competitive research doesn’t stop there.

Every domain in this piece was checked directly rather than pulled from a stale “best of” list and republished. Where a tool’s current status was ambiguous, inactive, quietly shut down, acquired and rebranded, that’s noted in its own entry rather than smoothed over. Talkwalker’s 2023 merger into Hootsuite gets a mention. So does WordStream’s rocky reputation since its LocalIQ acquisition, and X’s shrinking ad transparency scope. None of that changes whether a tool belongs on the list; it changes what you should expect when you actually open it.

Pricing mentioned throughout is what’s publicly listed at the time of writing. Ad-tech vendors change pricing often, sometimes without updating their own comparison pages, so treat every number here as a starting point for your own check, not gospel.

One more thing worth flagging before the list itself: several tools further down genuinely overlap. Minea, Dropispy, Sell The Trend, Ecomhunt, and Dropship.io all chase the same dropshipping audience with slightly different feature bundles, and paying for three of them rarely triples your insight. The write-ups below call out that overlap where it exists, rather than pretending each tool is a completely distinct category of its own.

Free, official ad libraries

These come straight from the platforms. No subscription, no trial that expires, no sales call. The tradeoff is search depth, you get what the platform decided to expose, nothing more, and in a couple of cases below, that’s less than it used to be.

1. Meta Ad Library

Every ad running on Facebook and Instagram lives here, whether the advertiser wants it found or not. Search by keyword, page name, or country, and you’ll see the creative, the copy, when it started running, and, for political and social issue ads, the spend range. For regular commercial ads, spend and targeting data are hidden, which is the library’s one real limitation.

Teams that use this well tend to build a short list of five or ten named competitors and check the library on a schedule, rather than searching blind. Blind keyword search works, but it buries you in noise once a category has more than a handful of active advertisers.

Core features: full-text search across active and inactive ads, filter by country and platform, ad start date, direct link to the advertiser’s Page.

Pros: completely free, no account required, covers every advertiser regardless of size, updates in near real time.

Cons: no spend data for commercial ads, no performance metrics, clunky for bulk research across dozens of competitors at once.

Best for: anyone starting out, or anyone who just needs to check what one specific competitor is running today.

Pricing: free.

2. Google Ads Transparency Center

Google’s answer to the same problem, covering Search, Display, YouTube, and Shopping ads. Type in a domain or advertiser name and you get every ad format that advertiser is running across Google’s network, region by region.

The interface is sparser than Meta’s. You won’t get impressions or spend. What you do get is the actual ad copy and creative, which is often the part that matters most, the headline someone tested and kept running. Shopping ads in particular are worth checking here since almost no paid tool captures them cleanly.

Core features: search by advertiser or domain, region-level filtering, coverage across Search, Display, Shopping, and YouTube.

Pros: free, official, covers formats no paid tool touches as cleanly (Shopping ads especially).

Cons: no historical archive beyond a limited window in most regions, no spend estimates, weak for bulk monitoring.

Best for: checking Search and Shopping ad copy for a known competitor.

Pricing: free.

3. TikTok Creative Center

Built more for creative inspiration than competitor stalking, but it doubles well as one. The Top Ads section shows what’s currently performing across regions and industries, filterable by objective, industry, and region, even if you can’t search a specific brand name directly the way you can on Meta.

Core features: trending/top-performing ads by industry and region, hashtag and sound trend data, creative benchmarking by format.

Pros: free, genuinely useful for spotting format trends before they saturate.

Cons: not built for advertiser-specific lookups, so tracking one named competitor is harder than on Meta or Google.

Best for: teams building TikTok creative who want to know what’s working in their category right now.

Pricing: free.

Visit TikTok Creative Center →

4. LinkedIn Ad Library

Quietly one of the more useful free tools if your competitors sell to businesses. Search any LinkedIn Page and see every sponsored ad they’re currently running or have run, including the exact copy and creative. For B2B, this is often more revealing than anything Meta shows, since LinkedIn ad copy tends to spell out the actual value proposition rather than lean on a punchy visual.

Core features: per-Page ad history, filter by date range, direct link to each ad’s landing page.

Pros: free, and genuinely strong for B2B, a segment most paid ad spy tools handle poorly.

Cons: no spend or impression estimates, and coverage only goes back so far.

Best for: B2B marketers tracking a specific list of named competitors.

Pricing: free.

5. X Ads Transparency Center

Worth including with a caveat up front: X’s ad transparency tooling has shrunk since it first launched. The original searchable center that showed all ads served in the past seven days was scaled back, and what remains today at the X Transparency Center leans heavily toward EU regulatory disclosure, advertiser identity, funding entity, targeting parameters, reach, rather than a full open library for every market.

Still useful if a competitor runs EU-facing campaigns, and worth checking periodically since X has changed this feature’s scope more than once. If your competitive research leans heavily on X/Twitter as a channel, treat this as a supplementary check rather than a primary source, SocialPeta’s cross-network coverage further down this list currently does a more complete job of capturing X ad creative outside the EU.

Core features: advertiser and funding-entity disclosure, targeting parameter summaries, reach data (primarily EU-scoped).

Pros: free, and it’s the only official window into X ad activity at all.

Cons: scope has narrowed over time; not a reliable full-market ad archive the way Meta’s library is.

Best for: checking EU-facing ad disclosure for a competitor running X campaigns.

Pricing: free.

Visit X Transparency Center →

6. Snapchat Political & Advocacy Ads Library

The name says it all. Snap built this library specifically for political and issue-based advertising, showing who paid for an ad, roughly how much, and who it targeted. Unlike Meta and TikTok, Snapchat doesn’t offer an equivalent public library for ordinary commercial ads, which limits how useful this is if your competitors are selling sneakers rather than running a campaign.

Core features: political/advocacy ad search, spend range disclosure, targeting criteria summaries.

Pros: free, and genuinely transparent within its narrow scope.

Cons: covers political and advocacy ads only, no visibility into standard commercial Snapchat ads.

Best for: researchers and advocacy groups tracking political ad spend on Snapchat specifically.

Pricing: free.

All-purpose paid ad spy tools

This is where the category gets serious. These tools scrape and index ads across networks the official libraries don’t cover well, and they add the layer the free tools skip entirely: filtering by engagement, run length, and audience signals, at a scale you can’t replicate by hand.

7. AdSpy

One of the oldest names here, and still one of the deepest databases, Facebook and Instagram ads going back years, searchable by keyword, advertiser, engagement count, and even the landing page domain. Affiliate marketers built their businesses on this tool for a reason.

It isn’t cheap, and it isn’t pretty. The interface feels like it hasn’t been redesigned since 2018 because, largely, it hasn’t. What it lacks in polish it makes up for in search precision, you can filter combinations that most competitors can’t touch, and the historical depth means you can trace how a single advertiser’s angle evolved over two or three years, not just what they’re running this week.

Core features: massive historical Facebook/Instagram ad database, advanced boolean search, engagement filtering, landing page search.

Pros: depth of historical data is unmatched, search filters are genuinely powerful, no gimmicks.

Cons: dated interface, no free plan, weekly access pricing feels steep for casual use.

Best for: affiliate marketers and performance teams who live in Facebook/Instagram ads daily.

Pricing: roughly $79 for a week or $149/month on the standard plan.

Visit AdSpy →

8. PowerAdSpy

Covers more networks than AdSpy, Facebook, Instagram, and it stretches into native and display placements too. The filtering is decent, not exceptional, but the price point makes it an easy entry for someone who isn’t ready to commit to AdSpy’s rates.

Where it earns its keep is breadth over depth, if you want a rough sense of activity across several networks without paying for four separate subscriptions, PowerAdSpy gets you most of the way there, even if no single network gets the AdSpy-level treatment.

Core features: multi-network ad search, keyword and interest targeting filters, ad copy and creative download.

Pros: more affordable than AdSpy, covers a wider spread of ad types.

Cons: database feels shallower on older ads, filtering is less precise at scale.

Best for: small teams testing the ad-spy category before committing to a pricier tool.

Pricing: starts around $49/month.

Visit PowerAdSpy →

9. BigSpy

The free tier is the real draw. You get limited daily searches across Facebook, Instagram, and a handful of other networks without paying anything, which makes it a reasonable way to test whether ad spying fits your workflow at all before upgrading.

Paid tiers unlock more networks, more daily search volume, and export options. It won’t out-search AdSpy on depth, but for the price, it doesn’t need to.

Core features: multi-platform coverage (Facebook, Instagram, TikTok, and more depending on plan), free daily search allowance, ad performance estimates.

Pros: genuinely usable free tier, broad network coverage for the price.

Cons: search results can feel noisier than premium competitors, support is slower on lower tiers.

Best for: anyone who wants to try ad spying without a credit card first.

Pricing: free tier available; paid plans from roughly $9.99/month.

10. Anstrex

Splits into two products, Anstrex for native ads (the “recommended articles” widgets you see at the bottom of news sites) and Anstrex Push, for browser push notification ads. Almost no other tool on this list covers native and push with this level of depth, which makes Anstrex a near-mandatory pick if your traffic strategy touches either channel.

Core features: native ad network search, push notification ad database, landing page and offer tracking.

Pros: unmatched depth in native and push, a channel most spy tools ignore entirely.

Cons: narrow focus, no use if your competitors only run social ads.

Best for: affiliate marketers and media buyers running native or push campaigns.

Pricing: from roughly $47.97/month.

Visit Anstrex →

11. Adplexity

Not one tool, a family of them. Adplexity Native, Adplexity Mobile, Adplexity Ecommerce, and Adplexity Push are each sold and priced separately, and each one is genuinely deep within its lane. Mobile alone claims coverage across well over a hundred carriers globally, which matters if your competitors run mobile-specific offers.

Buying more than one product adds up fast. Most teams pick the single vertical that matches their business and skip the rest, trying to run all four at once is rarely worth the combined bill unless you’re an agency covering every vertical for different clients.

Core features: vertical-specific databases (native, mobile, ecommerce, push), landing page capture, geo and carrier-level filtering on the Mobile product.

Pros: depth within each vertical is excellent, especially Mobile and Native.

Cons: each product is a separate subscription, so full coverage gets expensive quickly.

Best for: media buyers who know exactly which vertical they need and don’t need the rest.

Pricing: roughly $149/month per individual product.

Visit Adplexity →

12. WhatRunsWhere

Older tool, still relevant, particularly for display and native. It shows which publishers a competitor’s ads are running on, which is a detail most tools skip, knowing an ad exists is one thing, knowing where it’s placed is another, and that placement data can point you toward ad networks you hadn’t considered.

Core features: publisher-level placement data, display and native ad tracking, competitor spend estimates.

Pros: publisher/placement visibility is a genuine differentiator.

Cons: premium tier pricing is enterprise-flavored, and the interface shows its age.

Best for: media buyers deciding which ad networks and publishers to test next.

Pricing: premium plans run several hundred dollars per month; contact sales for current rates.

Visit WhatRunsWhere →

13. AdBeat

Similar territory to WhatRunsWhere, display ad intelligence with a focus on where competitors are buying placements and how long creatives stay live. AdBeat leans harder into spend estimation, giving rough budget ranges by campaign.

Core features: display ad database, spend estimation, publisher and network breakdowns, creative longevity tracking.

Pros: spend estimates help prioritize which competitors are worth watching closely.

Cons: priced for agencies and mid-size teams, not solo marketers.

Best for: agencies managing display campaigns for multiple clients who need budget benchmarks.

Pricing: from roughly $249/month.

Visit AdBeat →

14. AdClarity

Enterprise-grade, and it looks it. AdClarity (built by BIScience) pulls display, video, and social ad occurrences from over 650,000 publishers across 51 markets, which is a scale most of the tools on this list don’t attempt. Pricing reflects that, this isn’t a self-serve monthly plan, it’s a sales conversation.

Core features: cross-format ad tracking (display, video, social), global publisher network coverage, audience targeting insights, agency and brand-specific dashboards.

Pros: scale and market coverage genuinely rival the biggest names in the space.

Cons: not built or priced for small teams; requires a sales call to get pricing at all.

Best for: large brands and agencies needing global, cross-format ad intelligence.

Pricing: custom, quote-based.

Visit AdClarity →

15. AdSpyder

A newer entrant leaning on AI to do more of the analysis work, rather than just handing you a pile of matching ads, AdSpyder tries to surface which creative angles are actually driving engagement across the results it returns, and in some workflows can generate variations based on what it finds. Worth a look if you want the discovery and the first-draft ideation step in one place, especially for a small team without a dedicated creative strategist to do that pattern-spotting manually.

Core features: AI-assisted ad search and pattern detection, multi-network coverage, AI-generated creative variations.

Pros: the analysis layer saves time versus manually sorting through raw search results.

Cons: newer product, so historical archive depth doesn’t yet match established players like AdSpy.

Best for: teams who want AI-assisted pattern-spotting layered on top of standard ad search.

Pricing: tiered plans; check current rates on the site.

Visit AdSpyder →

16. SocialPeta

Broad network coverage is the selling point, Facebook, X, TikTok, YouTube, and several others feed into one search interface, with a particular strength in mobile app install ad creative that overlaps with the app-intelligence tools further down this list. If you need one dashboard covering several ad networks at once rather than juggling separate logins, this is built for that. It’s also one of the more complete options for X ad creative specifically, given how limited X’s own transparency tooling has become.

Core features: cross-network ad search, creative ranking by engagement, mobile app ad creative database.

Pros: network breadth in a single interface is genuinely convenient.

Cons: depth per individual network is generally shallower than a specialist tool built for just that channel.

Best for: teams running ads across many networks who want one dashboard instead of five.

Pricing: tiered plans; check current rates on the site.

Ecommerce and dropshipping ad spy tools

This corner of the category moves fast, largely because the people using these tools are hunting for products, not just ad angles. A winning ad and a winning product tend to travel together, so most tools here bundle both.

17. Minea

Started as a dropshipping product-research tool and grew into a genuinely broad ad spy platform covering Facebook, TikTok, Pinterest, and even print-on-demand niches. The product-plus-ad pairing is the whole point, you’re not just seeing an ad, you’re seeing which product it’s selling and how long it’s been running.

Core features: multi-platform ad search (Facebook, TikTok, Pinterest), product trend detection, store lookup for identified winning products.

Pros: strong at connecting an ad to the actual product and store behind it.

Cons: less useful outside ecommerce; B2B or service businesses won’t get much from it.

Best for: dropshippers and ecommerce sellers hunting for both product and ad ideas at once.

Pricing: from roughly $49/month.

Visit Minea →

18. Dropispy

Built specifically for dropshippers, and it shows in the workflow, ad search is paired directly with supplier lookups, so when you find a winning ad you can immediately check whether the product is sourceable through AliExpress or similar suppliers.

Core features: Facebook and TikTok ad search, supplier and product sourcing links, store analysis.

Pros: the ad-to-supplier pipeline saves a real step most tools leave you to do manually.

Cons: narrow use case outside dropshipping specifically.

Best for: dropshippers who want product sourcing baked into the ad research step.

Pricing: free tier available; paid plans from roughly $30/month.

Visit Dropispy →

19. Winning Hunter

An all-in-one ecommerce spy tool covering ads, products, and stores together, with a particular strength in surfacing which Shopify stores are scaling right now. If your competitive set is other Shopify sellers rather than big brands, this one’s built for exactly that fight.

Core features: ad search across major platforms, store performance tracking, product trend alerts.

Pros: store-level intelligence is a genuine edge for ecommerce-specific research.

Cons: overlaps heavily with Minea and PiPiADS, so paying for more than one rarely adds proportional value.

Best for: Shopify sellers tracking which competitor stores are actively scaling.

Pricing: from roughly $29.99/month.

Visit Winning Hunter →

20. PiPiADS

The name that comes up constantly in TikTok ad spy circles, and for good reason, its TikTok ad library is one of the deepest available, alongside solid Facebook coverage. Search by keyword, industry, or specific advertiser, and filter by likes, comments, and how long the ad’s been running.

Core features: deep TikTok ad database, Facebook ad coverage, engagement and run-time filtering, TikTok Shop analytics.

Pros: best-in-class for TikTok specifically, which few competitors match.

Cons: less depth outside TikTok and Facebook, don’t expect native or display coverage.

Best for: anyone whose ad spend leans heavily TikTok.

Pricing: from roughly $77/month, with a free trial period.

Visit PiPiADS →

21. Foreplay

Less about discovering new competitors, more about organizing the ads you’ve already found. Foreplay’s browser extension saves any ad you see into a shared “swipe file,” tagged and searchable by your whole team, which turns ad spying from a solo research task into a shared library everyone on the creative team can pull from.

Core features: browser-extension ad saving, shareable swipe files, ad brief and creative brainstorm tools, boards for organizing by campaign or client.

Pros: the collaboration layer is genuinely different from every other tool on this list, it’s built for teams, not solo research.

Cons: discovery search is thinner than dedicated spy tools; it’s better at organizing than hunting.

Best for: creative teams and agencies that need a shared, searchable ad reference library.

Pricing: from roughly $29.99/month.

Visit Foreplay →

22. Motion

Motion takes a different angle entirely, instead of helping you find competitor ads, it analyzes your own ad account with AI, cross-referencing your creatives against broader patterns to flag what’s actually driving performance. It’s less “spy on competitors,” more “understand what’s working and why,” which makes it a useful pairing with a pure discovery tool rather than a replacement for one.

Core features: AI-driven creative analysis, frame-by-frame video breakdown, cross-platform ad account integration, performance pattern detection.

Pros: genuinely different value than the rest of this list, turns your own ad data into insight, not just competitor screenshots.

Cons: it doesn’t replace competitor discovery; you’ll still want a spy tool alongside it.

Best for: performance marketing teams who already run ads and want deeper analysis of their own creative library.

Pricing: custom, based on ad spend and account size.

Visit Motion →

23. Peeksta

A newer ad-spy entry built around an AI-agent framing, instead of just returning a search results grid, Peeksta positions itself as automating parts of the research and competitor-monitoring process. Underneath that framing sits a fairly standard ad-spy database for Facebook and related networks, with the automation layer as the actual differentiator. Where it fits best is as a background watcher, set it against a fixed list of named competitors and let alerts do the checking, rather than opening the dashboard to search manually every week.

Core features: ad spy search, automated competitor monitoring and alerts, AI-assisted research workflows.

Pros: the automated monitoring angle reduces manual repeat-checking on a known competitor list.

Cons: a newer, smaller product than the established names in this group, less proven at scale.

Best for: teams that want ongoing automated alerts on a fixed competitor list rather than manual searches.

Pricing: tiered plans; check current rates on the site.

Visit Peeksta →

24. Sell The Trend

An AI-driven engine (the company calls it Nexus) that pairs ad spying with product research and supplier sourcing in one dashboard, aimed squarely at dropshippers who want to go from “here’s a trending ad” to “here’s the product listed and ready to import” without switching tools.

Core features: Facebook ad spy search, AI product trend detection, supplier sourcing and one-click store import.

Pros: the full pipeline from ad discovery to store import is genuinely efficient for high-volume dropshippers.

Cons: less relevant if you’re not running a dropshipping-style store model.

Best for: dropshippers who want ad research, product sourcing, and store automation bundled together.

Pricing: tiered monthly plans; check current rates on the site.

Visit Sell The Trend →

25. Ecomhunt

Leans on its ADAM AI and a “Saturation Inspector” feature to flag not just winning products but whether a niche is getting crowded before you commit budget to it. The Shopify Store Explorer lets you look inside stores that are already succeeding with a given product, which is a useful reality check before copying an angle.

Core features: AI product research (ADAM), market saturation detection, Shopify Store Explorer, competitor ad examples tied to each product.

Pros: the saturation warning is a genuinely useful filter most competitors don’t offer.

Cons: ad search depth is secondary to its product-research focus, don’t expect AdSpy-level ad filtering.

Best for: dropshippers who want product validation and saturation checks alongside ad ideas.

Pricing: tiered monthly plans; check current rates on the site.

Visit Ecomhunt →

26. Dropship.io

Combines product discovery with Facebook ad spend data and Shopify store analysis, plus a browser extension for one-click importing into your own store. It’s aimed at the same dropshipping audience as Minea and Ecomhunt, with its own take on connecting ad performance to actual sales data.

Core features: Facebook ad spend estimates, Shopify store analysis, product research, one-click import extension.

Pros: ties ad activity directly to estimated sales performance, not just creative visibility.

Cons: heavy overlap with Minea, Ecomhunt, and Sell The Trend, pick one rather than stacking several.

Best for: dropshippers who want spend-to-sales estimates alongside standard product research.

Pricing: tiered monthly plans; check current rates on the site.

Visit Dropship.io →

27. Store Leads

Not an ad spy tool in the strict sense, but a genuinely useful companion to one. Store Leads tracks over 13 million live ecommerce stores across roughly 100 platforms, showing which apps and technologies each one runs, social follower counts, and change logs of when tools were installed or removed. Pair it with an ad-spy tool and you can go from “this store is running an ad I like” to “here’s their entire tech and growth footprint” in a couple of clicks. Agencies use it as much for prospecting new clients as for competitive research, the same store database works both directions.

Core features: ecommerce store database (13M+ stores), installed app/technology detection, social follower tracking, historical change logs.

Pros: depth of store-level data is hard to find anywhere else at this scale.

Cons: no ad creative visibility at all, this is store and tech intelligence, not ad discovery.

Best for: agencies and app developers researching which stores and tech stacks are winning in ecommerce.

Pricing: free account available for basic lookups; paid plans for full data export.

Visit Store Leads →

Mobile app ad intelligence

Different game entirely. App install ads, in-app placements, and app store optimization all live in their own ecosystem, and the tools built for it look nothing like the Facebook-ad-focused options above.

28. Pathmatics (by Sensor Tower)

Sensor Tower acquired Pathmatics in 2021 and folded its digital ad intelligence into the broader Sensor Tower platform. What you get is omnichannel visibility into how brands spend on digital media, Facebook, Instagram, YouTube, Snapchat, Pinterest, Reddit, with creative-level detail across major global markets.

Core features: cross-channel spend intelligence, creative-level ad tracking, market-by-market coverage across North America, Europe, and select APAC/LATAM regions.

Pros: depth and market coverage suited to enterprise-scale competitive tracking.

Cons: enterprise pricing and onboarding, not a self-serve tool for smaller teams.

Best for: larger brands and agencies needing enterprise-grade, multi-market ad spend intelligence.

Pricing: custom, quote-based.

Visit Pathmatics →

29. AppTweak

App store optimization first, ad intelligence second, but the ad benchmarking piece is worth knowing about if you publish a mobile app. It shows how your ad campaigns perform against a defined competitor set, alongside the store-listing and keyword data AppTweak is best known for.

Core features: app store keyword tracking, ad benchmarking against competitor sets, review and rating intelligence.

Pros: ties ad performance directly to app store visibility, which most ad-only tools can’t do.

Cons: only relevant if you actually publish a mobile app; no use for web-only businesses.

Best for: app publishers who need ad and ASO data in one place.

Pricing: custom, tiered by app portfolio size.

Visit AppTweak →

30. Similarweb

Best known for traffic and website analytics, but its Digital Marketing Intelligence tier layers in paid and display ad data too, top publishers, ad networks, and traffic sources feeding a competitor’s site. It’s less about seeing the ad creative and more about understanding where the traffic behind it comes from.

Core features: traffic source breakdown, display advertising networks and publishers, referral and paid traffic estimates.

Pros: connects ad activity to actual traffic outcomes, which pure ad-library tools can’t show.

Cons: ad creative visibility is thinner than dedicated spy tools; traffic estimates are directional, not exact.

Best for: teams who care more about where competitor traffic originates than what the creative looks like.

Pricing: Digital Marketing Intelligence plans start around $125+/month, scaling with data depth.

SEO and PPC crossover tools

These weren’t built as pure ad spy tools. They were built for SEO and keyword research, and the ad-intelligence piece got bolted on because the same keyword data that tells you what to rank for also tells you what your competitors are bidding on.

31. SEMrush Advertising Research Toolkit

If you already use SEMrush for SEO, the Advertising Research module is sitting right there unused more often than it should be. It shows a domain’s estimated PPC keywords, ad copy history, and estimated traffic cost, alongside organic data in the same dashboard, which means you’re comparing paid and organic strategy side by side instead of juggling two tools.

Core features: PPC keyword estimation by domain, ad copy history, estimated traffic cost and position changes, competitor gap analysis.

Pros: if you’re already paying for SEMrush, this is close to a free add-on.

Cons: ad copy shown is text-only estimates, not the same visual creative capture you get from dedicated spy tools.

Best for: teams already in SEMrush for SEO who want paid search intel without a second subscription.

Pricing: included in SEMrush plans starting around $139.95/month (Pro tier and up).

Visit SEMrush →

32. SpyFu

Cheaper than SEMrush, narrower in scope, and genuinely good at the one thing it focuses on: showing every keyword a domain has ever bought or ranked for organically, plus every ad variation they’ve run against those keywords. For pure PPC competitor research, it’s hard to beat on price.

Core features: historical PPC keyword and ad copy database, organic ranking history, competitor domain comparison.

Pros: historical depth on PPC keywords is excellent for the price point.

Cons: interface and reporting feel dated next to newer competitors; less useful for social or display ads.

Best for: search marketers who want deep historical PPC keyword data without an enterprise budget.

Pricing: from roughly $39/month.

Visit SpyFu →

33. Serpstat

An all-in-one SEO suite that happens to include a PPC research module, competitor ad keywords, estimated costs, and ad copy examples pulled from Google’s search results. It won’t out-depth SpyFu or SEMrush on ads specifically, but if you need SEO, backlink, and light PPC research in a single subscription, Serpstat covers all three reasonably well.

Core features: PPC keyword research, competitor ad copy examples, combined SEO/PPC competitor analysis.

Pros: good value if you need SEO and PPC research together rather than paid ad depth alone.

Cons: the ads module is genuinely secondary to its SEO features, treat it as a bonus, not the main event.

Best for: smaller teams wanting one affordable tool for SEO and lightweight PPC competitor checks.

Pricing: from roughly $69/month.

Visit Serpstat →

34. Ahrefs

Primarily an SEO and backlink tool, and most people never open the Paid Keywords report tucked inside Site Explorer. It’s there. Point it at a competitor’s domain and it estimates every keyword they’re bidding on in Google Ads, alongside the actual ad copy pulled from the SERPs.

Core features: paid keyword estimation via Site Explorer, ad copy examples from SERP data, traffic value estimates.

Pros: if you’re already paying for Ahrefs for SEO, this comes at no extra cost.

Cons: not built as a standalone ad spy tool, nobody should subscribe to Ahrefs for this feature alone.

Best for: existing Ahrefs users who want a quick paid-keyword gut check without leaving the tool.

Pricing: included in Ahrefs plans starting around $129/month.

35. Adthena

The one genuine specialist in this group, Adthena’s entire product is built around paid search competitive intelligence, using its “Whole Market View” technology to map keyword targeting, ad copy, and market share shifts across an entire category, not just one named competitor at a time. It’s expensive, and it’s built for it: expect enterprise-level quotes, sometimes reported north of $3,000 a month, which puts it out of reach for anyone outside a serious paid search budget.

Core features: whole-market PPC share tracking, competitor keyword and ad copy monitoring, SEM and SEO landscape mapping.

Pros: unmatched depth for category-wide paid search intelligence rather than one-off competitor checks.

Cons: pricing puts it firmly in enterprise territory; overkill for small or mid-size teams.

Best for: enterprise paid search teams tracking market share across an entire category.

Pricing: custom, enterprise-quote (commonly reported in the low thousands per month).

36. SE Ranking

An affordable, all-in-one SEO platform that includes competitor and PPC analysis features without the price tag of SEMrush or Ahrefs. It’s a favorite for small teams and freelancers getting into competitive research for the first time, trading some depth for a genuinely approachable price and interface.

Core features: keyword research, competitor PPC and organic analysis, rank tracking, white-label reporting.

Pros: price-to-feature ratio is strong for small teams new to competitive intelligence.

Cons: PPC-specific depth trails the dedicated specialists like SpyFu and Adthena.

Best for: small agencies and freelancers wanting SEO and light PPC competitor data in one affordable tool.

Pricing: from roughly $65/month.

37. WordStream

Worth a mention with an honest caveat. WordStream built a name on quick, actionable PPC insights and a genuinely popular free Google Ads performance grader, aimed at agencies managing smaller budgets and local clients who need fast answers, not deep dashboards. Since its acquisition and rebrand under LocalIQ, some longtime users have questioned how actively it’s still being developed, and reviews mention rigid multi-month contracts as a friction point.

Core features: free Google Ads performance grader, PPC campaign management across Google and Microsoft Ads, quick-turnaround optimization suggestions.

Pros: the free grader is a genuinely fast way to spot obvious account issues, yours or (with access) a client’s.

Cons: product direction feels less certain post-acquisition; contract terms have drawn complaints.

Best for: agencies managing smaller local PPC budgets who want fast, no-frills optimization checks.

Pricing: custom agency pricing; free grader tool available without a subscription.

Broader competitive and consumer intelligence

Ads are one signal. These ten track a wider picture, pricing pages, messaging changes, product launches, social sentiment, consumer purchase behavior, with ad monitoring as one feature among several. Worth knowing about even if ads aren’t your only concern.

38. Kompyte

An AI-driven competitive intelligence platform that monitors competitor websites, review sites, social media, and search rankings continuously, then surfaces changes automatically instead of making you check manually. Ad monitoring sits alongside messaging and pricing-page tracking, all feeding into alerts your sales and product teams can actually use.

Core features: automated competitor website and pricing monitoring, social and review site tracking, battlecards for sales teams, alert digests.

Pros: covers far more than ads, genuinely useful for product and sales teams, not just marketing.

Cons: ad-specific detail is shallower than dedicated ad spy tools; it’s a generalist, not a specialist.

Best for: teams that need one dashboard tracking competitors across marketing, sales, and product simultaneously.

Pricing: custom, quote-based.

39. Crayon

Similar territory to Kompyte, pricing intelligence, website change tracking, and real-time talking points for sales teams, with a strong reputation specifically among enterprise competitive intelligence teams. Ads are tracked as part of the broader monitoring, not the headline feature.

Core features: pricing and website change monitoring, sales battlecards, competitive newsletters and digests.

Pros: strong at turning raw competitor changes into something sales reps will actually read.

Cons: enterprise pricing and onboarding; overkill if ads are genuinely your only concern.

Best for: enterprise competitive intelligence teams supporting sales enablement.

Pricing: custom, quote-based.

40. Klue

Pairs competitive intelligence with win-loss analysis, which is a combination few tools attempt. The idea is that knowing why you lost a deal to a competitor matters as much as knowing what ad they ran to get the lead in the first place, Klue tries to close that loop.

Core features: competitive intelligence platform, win-loss interview and analysis tools, AI-generated battlecards, integrations with CRM and sales tools.

Pros: the win-loss integration is a genuine differentiator for B2B sales teams.

Cons: ad tracking is one small piece of a much bigger (and pricier) platform.

Best for: B2B sales and product teams that need competitive intel tied directly to deal outcomes.

Pricing: custom, quote-based.

41. Rival IQ

Leans social. Rival IQ tracks a competitor set’s social media performance, including paid social ad activity where visible, alongside organic post performance, hashtag use, and engagement benchmarking. If your main question is “how does our social presence compare to three named competitors,” this is built for exactly that comparison.

Core features: social media competitive benchmarking, paid and organic post tracking, hashtag and content analysis, automated reporting.

Pros: genuinely strong at social benchmarking across multiple competitors at once, not just one-off ad lookups.

Cons: less depth on non-social ad formats like display or search.

Best for: social media managers benchmarking a defined competitor set.

Pricing: from roughly $239/month.

42. Moat (Oracle Advertising)

Now part of Oracle’s advertising stack, Moat built its name on ad verification and attention measurement, and it still does creative-level analytics few tools match, viewability, attention time, and creative performance benchmarking layered on top of standard ad tracking.

Core features: ad verification and viewability measurement, creative-level performance benchmarking, cross-format analytics (display, video).

Pros: the attention-measurement layer is genuinely unique among tools on this list.

Cons: enterprise-focused, both in price and in the sales process required to get access.

Best for: large brands and agencies that need verification-grade ad measurement, not just discovery.

Pricing: custom, quote-based (enterprise).

43. Brandwatch

The closest thing the enterprise market has to a pure consumer intelligence platform. Its core strength is depth, historical social and forum archives going back over a decade, review-site coverage most competitors skip, and an AI analysis layer the company calls Iris. Ad monitoring here means understanding how consumers are actually reacting to a competitor’s campaign, not just cataloging the creative itself.

Core features: deep historical social listening archive, forum and review-site monitoring, AI-powered sentiment and trend analysis (Iris).

Pros: historical depth and consumer sentiment analysis are genuinely best-in-class.

Cons: built for consumer intelligence broadly, not ad creative discovery specifically, pair it with a dedicated ad spy tool.

Best for: enterprise brand and insights teams who need to understand consumer reaction to competitor campaigns.

Pricing: custom, quote-based (enterprise).

Visit Brandwatch →

44. Meltwater

Leans harder into media monitoring and PR than Brandwatch does, letting teams track earned media coverage alongside social conversation for a fuller picture of a competitor’s communications strategy, announcements, press hits, and the paid amplification that often follows them.

Core features: media and PR monitoring, social listening, competitor campaign and announcement tracking, sentiment analysis.

Pros: the PR-plus-social combination gives a fuller communications picture than social listening alone.

Cons: not an ad creative discovery tool, think communications intelligence, not ad library.

Best for: comms and PR teams tracking a competitor’s full media footprint, not just their ads.

Pricing: custom, quote-based (enterprise).

45. Talkwalker

Now operating under Hootsuite following a 2023 merger, Talkwalker’s differentiator has long been its visual and video AI, it can analyze images, video, and even speech content across news and social sources, not just text. For ad-adjacent research, that means catching visual campaign trends that text-based monitoring tools miss entirely.

Core features: visual and video AI content analysis, global language coverage, cross-platform social and news monitoring.

Pros: visual/video analysis catches campaign trends text-only tools simply can’t see.

Cons: now folded into the Hootsuite ecosystem post-merger, which has shifted some product and pricing structures.

Best for: global brands needing visual/video-aware social and media monitoring across many languages.

Pricing: custom, quote-based (enterprise).

46. Owler

Less a monitoring platform, more a company-intelligence database, funding history, revenue estimates, leadership changes, and competitor news alerts delivered as a daily or weekly digest. It won’t show you an ad, but it’ll tell you a competitor just raised a funding round, which usually precedes a spike in ad spend by a few weeks. That lead time is the real value, checking Owler alongside an ad spy tool means you’re watching for the funding event that predicts the ad spend increase, not just reacting once the new campaigns are already live.

Core features: company profile database, funding and revenue estimates, competitor news alerts, crowdsourced company comparisons.

Pros: free tier is genuinely useful for early-warning signals on competitor funding and leadership changes.

Cons: zero ad creative visibility, this is business intelligence, not ad monitoring.

Best for: anyone who wants an early signal that a competitor is about to increase ad spend, before the ads actually show up.

Pricing: free tier available; paid plans for deeper company data and alerts.

47. Numerator

A consumer and retail intelligence company built on first-party purchase data from over a million US households. Its Promotions Intel and Promo Insights products track how retail promotions and advertised deals actually translate into purchase behavior, going back over three decades of trade promotion history. This is less “here’s the creative” and more “here’s whether the promotion actually moved product,” which matters more to a retail or CPG brand than a screenshot ever could.

Core features: first-party consumer purchase data, promotion and trade-spend tracking, promo-to-purchase behavior linking, weekly ad/promo dashboards.

Pros: connecting promotional activity to actual purchase behavior is a level most ad tools never reach.

Cons: built for retail and CPG promotional strategy specifically, not general ad creative research.

Best for: retail and CPG brands measuring whether competitor promotions actually shift consumer purchasing.

Pricing: custom, quote-based (enterprise).

Tech stack and domain intelligence (bonus)

These three don’t show ad creative at all. They answer a different, closely related question: what is this competitor actually running under the hood, and who else is connected to them. Skip this section if ad creative is genuinely all you need, keep reading if you’re building a fuller competitive picture.

48. BuiltWith

Points it at any domain and it returns the technology stack behind it, advertising pixels, analytics tools, A/B testing platforms, ecommerce systems, and well over a hundred thousand other technologies it tracks across a continuously refreshed database of hundreds of millions of domains. For ad research specifically, the pixel and tag detection tells you exactly which ad networks and retargeting tools a competitor has installed, which is a detail no ad library shows.

Core features: technology stack detection (ad pixels, analytics, ecommerce platforms), historical stack change tracking, lead list generation by technology used.

Pros: pixel-level detection reveals exactly which ad networks and retargeting tools a competitor relies on.

Cons: tells you what’s installed, not what the ads look like, pair with an actual ad spy tool for the full picture.

Best for: anyone who wants to know exactly which ad networks and marketing tech a competitor’s site is running.

Pricing: free basic lookups; paid plans for full historical data and bulk export.

Visit BuiltWith →

49. Wappalyzer

A lighter, faster alternative to BuiltWith, delivered mainly as a browser extension that identifies a site’s CMS, ecommerce platform, analytics, marketing tools, and more the moment you land on the page, no separate lookup step required. It covers over a thousand technologies across dozens of categories.

Core features: browser-extension technology detection, CMS/ecommerce/marketing tool identification, bulk lookup via API.

Pros: the instant-on browser extension is faster for casual, one-off checks than a separate lookup tool.

Cons: historical archive and bulk data depth trail BuiltWith for serious research use.

Best for: quick, casual checks of what a competitor’s site is running while you’re already browsing it.

Pricing: free browser extension; paid API/bulk plans for larger-scale lookups.

Visit Wappalyzer →

50. SpyOnWeb

An old-school but still genuinely handy tool for a very specific question: does this competitor share an analytics ID, ad network ID, or hosting fingerprint with other domains. That kind of shared-ID detection can surface a competitor’s other brands, sister sites, or a parent company you didn’t know existed, useful context before assuming you’re only up against the one storefront you can see.

Core features: shared analytics/ad-ID detection across domains, related-domain discovery, hosting and DNS fingerprint lookup.

Pros: genuinely useful for uncovering a competitor’s other properties that aren’t obviously connected.

Cons: interface is dated and results can be hit-or-miss depending on how well a site’s tracking IDs are exposed.

Best for: researchers trying to map out a competitor’s full portfolio of sites and brands.

Pricing: free for basic lookups.

Comparison table: all 50 tools side by side

A fast reference if you’re deciding between two or three of the above. Pricing is approximate and public-facing as of this writing, confirm current rates on each vendor’s site before buying, since ad-tech pricing shifts more often than most software categories.

How to actually pick one

Start free. Always. Meta, Google, TikTok, LinkedIn, X, and Snapchat’s libraries cost nothing combined, and will tell you within an hour whether you even need a paid tool.

If the answer is yes, match the tool to your channel, not to whichever one has the best marketing site. Ecommerce and dropshipping teams should look at Minea, PiPiADS, Ecomhunt, or Dropship.io before anything else on this list, there are eleven options in that one category alone now, and picking two rather than all eleven is the actual skill. B2B teams tracking a short, named list of rivals get more from Klue or Crayon than from any pure ad-scraping tool, because ads are one signal among many in a B2B sales cycle.

Agencies juggling multiple clients tend to land on AdBeat, WhatRunsWhere, or AdClarity, mostly because those tools were built with client reporting in mind from day one. Retail and CPG brands care more about Numerator’s promo-to-purchase data than any ad screenshot. And if you’ve never once checked what technology a competitor’s site is actually running, BuiltWith is a five-minute detour worth taking before you buy anything else on this list.

One tool rarely covers everything, and with fifty options now on the table, resist the urge to trial all of them at once, that’s a fast way to spend a month comparing dashboards instead of actually watching competitors. A common, sensible stack looks like this: a free official library for spot checks, one paid ad-spy tool matched to your primary channel, and, only if ads are part of a bigger competitive picture you’re building for leadership, one of the broader intelligence platforms layered on top.

Buy the second tool only after the first one has actually changed a decision you made.

Common mistakes teams make with these tools

Buying the tool is the easy part. Most of the value gets lost in how it’s actually used afterward, and the same handful of mistakes show up across teams that are otherwise good at marketing.

Copying the ad instead of the pattern. The single most common failure. Someone finds a competitor’s high-performing hook, swaps the logo, and ships it within the hour. Sometimes it works, briefly. More often it flops, because the original ad was tuned to that brand’s specific audience, offer, and trust level, none of which transfer with a palette swap. The tools show you what worked. They don’t show you why, and skipping that step is how a promising find turns into a wasted ad budget.

Watching too many competitors at once is the second trap. Ten named competitors sounds thorough. In practice it means a shallow, once-a-month glance at each one instead of a genuine read on the two or three who actually move the market you’re in. Three well-watched competitors beat ten loosely-watched ones, every time.

Underrated.

That’s the third mistake: treating ad longevity as noise instead of signal. An ad that’s been running for eight weeks isn’t lucky. Ad platforms penalize weak creative with rising costs, so anything still live after that long has cleared a real bar. Teams that only look at ads posted this week miss the strongest evidence sitting right in front of them, the ones that have survived long enough to prove themselves.

Buying a $150-a-month tool to check one competitor twice a year is a mismatch nobody budgets for on purpose, and it happens constantly. If the actual need is occasional and narrow, a free official library covers it. Paid tools earn their keep on frequency and volume, not on the occasional curiosity check.

Last one: no one owns it. A tool gets purchased, someone logs in twice in the first month, excitement fades, and the subscription quietly renews for a year of nobody actually checking it. Ad spying only pays off as a habit, a specific person, a specific day of the week, a specific short list of what to check. Without that, even the best tool on this list turns into a line item nobody remembers signing up for.

FAQs

Is it legal to spy on competitor ads?

Yes. Every tool on this list works from ads that are already public, anyone scrolling Facebook or searching Google can see the same creative. Legal risk shows up if you copy protected elements (trademarked names, distinctive taglines, licensed imagery) rather than the strategy behind an ad. Studying an angle is fine. Tracing it is not.

Which ad spy tool is actually free?

Meta Ad Library, Google Ads Transparency Center, TikTok Creative Center, LinkedIn Ad Library, X Ads Transparency Center, and Snapchat’s Political & Advocacy Ads Library all cost nothing, though Snapchat’s is limited to political ads. BigSpy, Dropispy, Store Leads, Owler, BuiltWith, Wappalyzer, and SpyOnWeb also offer usable free tiers for basic lookups.

What’s the difference between an ad spy tool and a competitive intelligence platform?

Ad spy tools (AdSpy, Minea, PiPiADS, and similar) focus specifically on finding and cataloging ad creative. Competitive intelligence platforms (Kompyte, Crayon, Klue, Brandwatch, Meltwater) track a much wider set of signals, pricing pages, product changes, review sentiment, PR coverage, sales talking points, with ad monitoring as one feature among several.

Do these tools show exactly how much a competitor spends?

Rarely, and never with full accuracy. Free platform libraries hide commercial ad spend entirely. Paid tools like AdBeat, WhatRunsWhere, and AdClarity provide spend estimates based on modeling, not verified figures pulled from the advertiser’s account. Treat every spend number as a directional range, not a fact.

Which tool is best for a small business on a tight budget?

Start with the six free official libraries, they cover more ground than most small businesses expect. If you need more, BigSpy’s free tier or Dropispy’s entry plan (around $30/month) are the least expensive paid options with real functionality.

Can I track a competitor’s ads without them knowing?

Yes. None of the tools on this list notify the advertiser when their ads are searched or viewed. You’re browsing public information the same way a customer would, just at a larger scale and with better filtering.

How often should I check competitor ads?

Weekly is a reasonable baseline for an active category. If you’re in a slower-moving B2B niche, monthly is often enough. The signal that matters most isn’t a single ad, it’s a pattern holding steady for weeks, which is usually a sign the advertiser has found something that converts.

Do I need more than one ad spy tool?

Most businesses don’t. One tool matched to your primary channel, plus the free official libraries for spot checks, covers the vast majority of use cases. Add a second tool only when you’ve hit a specific gap the first one genuinely can’t fill, different channel, different market, or a broader intelligence need beyond ads alone.

Are tools like BuiltWith or Owler actually “ad spy” tools?

Not in the strict sense, neither shows you an ad’s creative. They’re included because they answer questions that sit right next to ad spying: what ad tech and pixels a competitor’s site runs (BuiltWith), or whether a competitor just raised funding that’s likely to show up as increased ad spend a few weeks later (Owler). Useful context, not a replacement for an actual ad library.

What happened to iSpionage and BrandTotal?

iSpionage shut down in September 2025. BrandTotal’s own status is unclear enough, some listings describe it as inactive since 2022, others suggest it’s still running, that it’s been left off this list rather than risk pointing you at a dead subscription. Ahrefs and Rival IQ cover similar ground for PPC keyword research and social benchmarking, respectively. It’s a useful reminder to bookmark this kind of list loosely: ad-tech vendors merge, rebrand, and disappear often enough that any “best tools” roundup, this one included, is worth a fresh look every six months or so rather than treated as permanent.
