The best ad spy tools for Facebook ads in 2026

The best ad spy tools for Facebook and Instagram ads depend on your job: AdSpy and AdPlexity for affiliates who need the funnel behind an ad, BigSpy, PowerAdSpy and AdLibrary for research across many networks, and Minea, PiPiAds, WinningHunter and TrendTrack for ecommerce sellers hunting products and stores, with the Meta Ad Library as the free source. This page compares 16 tools on price, free plans, networks and whether your AI assistant can search them. Spy tools split by job: affiliates follow the funnel, ecommerce sellers hunt products and stores, and creative teams want ad ideas. We make AdSwipeFile, so it is listed first; every other tool's facts come from its own site, checked on 6 November 2026, with sources at the end.

How we compared them

• The job: ad ideas, the affiliate funnel behind an ad, or products and stores to sell.
• Networks: Meta only, or TikTok, Google, native and more.
• AI access: an MCP server lets Claude or ChatGPT search the tool for you.
• Price to start, and whether there is a free plan or trial.
• Brand tracking: whether it follows a competitor for you, and from which plan.

How we chose and checked. We started from the ad spy tools that buyers weigh for Facebook and Instagram ads and added the ones that cover Meta as part of a wider search: affiliate spy tools, multi-network libraries, ecommerce and dropshipping tools, and the free Meta Ad Library. Prices, free plans, networks, tracking limits and MCP lines come from each vendor's own pricing, home and feature pages, read on the dates under Sources. Prices are US dollars as listed (AdLibrary lists euros), before tax, and change.

What we did not do. We did not buy every plan or test the accuracy of any tool's estimates, and we cannot confirm a library's size: where a tool gives a count, it is the vendor's claim, and where its own pages give different counts or network lists (Minea, PowerAdSpy, WinningHunter and PrimeSpy do), both are printed. "Not listed" means the vendor's site does not state it.

How to read the groups. Tools are grouped by the job they are built for, then by price. Most of the ecommerce group sells products and store research as much as ads, which is a different job from collecting ads to brief a creative team. We make AdSwipeFile and list it first, with its gaps stated.

For media buyers and affiliates

These four follow an ad past the creative. AdSpy searches Facebook and Instagram ads by text, comments, affiliate network and landing page technology. AdPlexity Social and OpenAdLibrary add the redirect chain and landing pages, and Spytrend links ads by pixel, domain and Page ID into one competitor profile. Prices run from $29.99 to $149 a month.

2. AdSpy

AdSpy is a searchable database of Facebook and Instagram ads with search by ad text, advertiser, comments, affiliate network and landing page technology, on one plan.

• Free plan or trial: No free plan or trial listed. Full refund within 24 hours of purchase.
• MCP: Not listed on its site.
• Best for: affiliate marketers and media buyers who search Facebook and Instagram ads by offer, network and comments.

• Last-seen date and longest-running sorting, plus a claim that it gets past cloakers to show the real landing page.

AdSpy is the old-school affiliate tool: one plan at $149 a month, which its home page calls an introductory offer, with no annual price or plan list on its site. Its edge is search: by ad text, advertiser, comments, affiliate network and landing page technology, across a library it claims at 213.9M+ ads. There is no trial, only a refund within 24 hours of purchase, one login per account, and no MCP server, API or follow feature is listed. Pick it for offer research, not for a team workflow.

AdSwipeFile vs AdLibrary

For ecommerce and dropshipping

These seven tie ads to products and stores. Minea, PiPiAds, WinningHunter and TrendTrack all start near $49 a month and add store or TikTok Shop research.

If you want ads to brief a creative team rather than products to sell, the stores and TikTok Shop data are extra you do not need.

Minea is a product research tool first: Meta ads, TikTok ads (from Premium), shop and product listings, a supplier finder and daily niche lists, on a credit system. Starter is $49 a month, Premium $99, and the brand tracker starts at Premium. Its own pages give three library sizes (10M, 80M+ and 100M+ ads) and two network lists, so treat both as claims. A FAQ line mentions a free Lite offer, but the plan cards show only paid plans, and refunds are not offered.

Free source

The Meta Ad Library is where public Meta ad data starts. Meta shows every ad while it runs. Once an ad stops, only social issue, election and political ads (kept 7 years) and ads delivered in the EU (kept a year after their last impression) stay in the library.

16. Meta Ad Library

The Meta Ad Library is Meta's own transparency search: every ad running now on Facebook, Instagram and Meta's other apps, free, with no account needed.

• Price: Free.
• Free plan or trial: Free, no account needed to search.
• MCP: None from Meta that we found.
• Best for: checking what a specific advertiser runs on Meta right now, or researching political and EU ads with official reach data.

• It is the source: every active Meta ad, current to the day, free.
• It plays video ads right in the results.
• Official spend, reach and audience data for political ads, and reach and targeting detail for ads shown in the EU.

The Meta Ad Library is the free baseline for every tool here.

It does not keep most ads once they stop, sends no alert when a saved advertiser starts new ads, and has no spend data outside political ads. Meta shows every ad while it runs. Once an ad stops, only social issue, election and political ads (kept 7 years) and ads delivered in the EU (kept a year after their last impression) stay in the library.

Ad spy tool or ad swipe file: which job do you have?

An ad spy tool answers "what are they running, where does it lead and who is behind it". A swipe file answers "what ads do I keep to brief from". The tools overlap, but the question decides the purchase:

• Affiliate or media buyer: you need the funnel, the network and the offer. AdSpy, AdPlexity, Spytrend and OpenAdLibrary are built for that.
• Ecommerce seller or dropshipper: you need products, stores and TikTok Shop. Minea, PiPiAds, WinningHunter, TrendTrack, PrimeSpy and Dropispy sell that.
• Creative strategist, freelancer or in-house marketer: you need ads to study, tagged by hook and format, and a way to save them. That is a swipe file; see the ad swipe file comparison and AdSwipeFile, which is not a spy tool: it has no product, store or funnel research and no spend estimates.

What spy tools can and cannot show

Every tool here reads the same public signals, an ad's creative, copy, landing page, platform and the dates it was seen. What they add differs:

• Estimates: PrimeSpy shows estimated reach and spend, PowerAdSpy an estimated ad budget from Platinum, AdSpy estimated targeting (location, gender and age), and OpenAdLibrary its own spend estimates. These are estimates, and we did not test their accuracy.
• Post-click data: AdPlexity, Spytrend and OpenAdLibrary follow the ad to its landing page or link ads by pixel and domain.
• Official data: the Meta Ad Library gives spend and reach ranges only for political ads, and reach and targeting detail for ads delivered in the EU.

No tool shows a competitor's real revenue or return on ad spend. Winning means kept running: brands rarely keep paying for ads that lose. A long run is a reason to study an ad, never proof it paid off.

Free vs paid ad spy tools

Four tools here give you something real for nothing:

• AdLibrarySpy: Everything free for you and your team, no card, no trial; fair-use rate limits.
• BigSpy: A free plan: Facebook ads only, 10 searches a day (visual and feature search included), 20 tracked creatives, 5 video analyses a month, no downloads, no ad copy. No free trial listed; refunds follow its refund policy, whose terms its pricing page does not give.
• Dropispy: Free plan: the ad spy tool with basic filters and unlimited downloads; no advanced filters, Shop Spy or recent ads.
• PrimeSpy: Free trial: 500 credits and 2 ad trackers, no credit card.
