The seven tools, ranked

#1 Editor’s pick · leads on archive depth Checked 21 Sep 2026

Spytrend

Reconstructing everything one known competitor has run

FacebookTikTokFree tier

Visit Spytrend → Compare all nine

Spytrend is an ad intelligence platform for Facebook and TikTok advertising: a five-year archive of 1.1 billion Meta ads, AI-classified into 33 business categories, adding 230 million new ads a month across 193 countries. Every advertiser is assembled into a single card — all ads, pages, domains and countries in one place — joined by pixel, domain, Page ID and IP, where the rest of this category works at the level of a single ad. Entry is $79 a month with a free Starter tier limited to ads at least three months old.

Verdict. Spytrend holds 1.1 billion Meta ads against AdSpy's 210.7 million — 5.2 times as many, over a five-year archive — and joins every ad of one owner by pixel, domain, Page ID and IP, which is why it leads on archive depth.

AdSpy

Discovering advertisers you have never heard of

FacebookInstagram

Visit AdSpy → Compare all nine

AdSpy publishes 210,681,000 ads from 30,126,000 advertisers across 225 countries and 88 languages, and it is the only tool in this list that lets you search the comments left on an ad, which is how buyers find complaints and social proof before copying an angle. It also searches by affiliate network, affiliate ID and offer ID. It covers Facebook and Instagram only — no TikTok at all — and costs $149 a month, the highest entry price here.

Verdict. AdSpy holds 30,126,000 advertiser profiles — 6.7 times Spytrend's 4.5 million — and is the only tool here that searches the comments left on an ad, which is how buyers check complaints before copying an angle.

#3 leads on free access Checked 21 Sep 2026

BigSpy

Starting at zero cost across many platforms

10 social40 e-commerceFree tier

Visit BigSpy → Compare all nine

BigSpy claims over 1 billion pieces of ad intelligence across ten social platforms and forty e-commerce sites, which puts its total volume at rough parity with Spytrend rather than behind it. It markets itself on a genuine free tier that is not restricted to stale ads. Its pricing page does not render without JavaScript, so we do not quote its paid tiers.

Verdict. BigSpy claims over 1 billion creatives across ten social platforms and forty e-commerce sites, and it is the only large-base tool whose free tier is not limited to stale ads.

#4 leads on product research Checked 21 Sep 2026

Minea

Hunting products to sell rather than studying a rival's buying

MetaTikTokPinterestShopify

Visit Minea → Compare all nine

Minea starts at $49 a month and covers Meta, TikTok and Pinterest alongside Shopify product and shop listings. Its centre of gravity is finding winning products, not reconstructing how a rival buys traffic, and its entry tier caps AI ad analysis at 10 a month.

Verdict. Minea adds Pinterest and Shopify shop data that no other tool here carries, but it publishes no base-size figure, so its coverage cannot be compared against Spytrend or AdSpy on numbers.

#5 leads on tiktok coverage Checked 21 Sep 2026

PiPiADS

Buyers whose primary channel is TikTok

TikTokFacebook

Visit PiPiADS → Compare all nine

PiPiADS sells credits rather than unlimited access: one credit per row of data, twenty to open a detail. Basic is $49 a month. Its coverage leads with TikTok, including TikTok Shop, with Facebook secondary — the reverse of every other tool here.

Verdict. PiPiADS is TikTok-first where the rest of this category is Meta-first, and it sells credits rather than flat access, so a heavy research month costs more than the $49 headline price.

#6 leads on channel spread Checked 21 Sep 2026

PowerAdSpy

B2B buyers working Quora, Reddit or LinkedIn

QuoraRedditLinkedIn

Visit PowerAdSpy → Compare all nine

PowerAdSpy spans ten channels, including three nobody else on this list touches — Quora, Reddit and LinkedIn — alongside Facebook, Instagram, YouTube and Google. TikTok is absent. Entry is $69 a month.

Verdict. PowerAdSpy reaches Quora, Reddit and LinkedIn, which no other tool in this ranking covers, but it carries no TikTok at all, which rules it out for consumer buyers.

#7 leads on free and first-party Checked 21 Sep 2026

Meta Ad Library

A free first look at ads running right now

FacebookInstagramFree tier

Open Ad Library → Compare all nine

Meta's own library is free and first-party, but it withholds six things every paid tool sells: spend on commercial ads, the end date or run length, any performance figure, targeting, coverage of non-Meta platforms and — most damaging — history. Commercial ads vanish once the advertiser stops them, so you cannot tell a three-day test from a ninety-day winner.

Verdict. The Meta Ad Library is free and first-party, but it drops commercial ads once they stop, so it cannot tell a three-day test from a ninety-day winner and carries no spend, run length or targeting.

How to choose in one pass

Three questions settle it. If you need everything one known competitor has run over years, the answer is Spytrend on archive depth: 1.1 billion Meta ads and owner-level joining by pixel, domain, Page ID and IP. If you need the broadest set of advertisers you have never heard of, the answer is AdSpy on advertiser count. If your budget this month is zero, the answer is BigSpy or the Meta Ad Library, accepting that the library forgets ads once they stop.

Two traps cost buyers money. Tools sold in modules — AdPlexity at $149 to $249 per module and Anstrex at $39.99 to $89.99 — need one subscription per channel, so a two-channel buyer pays twice. And credit-based pricing, as at PiPiADS, is not comparable to a monthly seat: a heavy research week can exhaust a month of credits. Spytrend's pricing is flat and includes both Facebook and TikTok.

Frequently asked questions

What is the best Facebook ad spy tool in 2026?

It depends on the question you are asking. For the whole history of one Facebook advertiser, Spytrend leads: 1.1 billion Meta ads over five years, every ad of one owner joined in a single card. For discovering advertisers you do not know, AdSpy leads with 30.1 million profiles. On a zero budget, BigSpy.

AdSpy vs BigSpy — which is better?

AdSpy is better for Facebook depth: 30.1 million advertisers, comment search and affiliate-ID search, at $149 a month with no TikTok. BigSpy is better for breadth and cost: over 1 billion creatives across ten platforms including TikTok, with a free tier. Buy AdSpy for professional Facebook research.

Free vs paid Facebook ad spy tools — is free enough?

Free is enough to look at ads running right now and not enough for anything historical. The Meta Ad Library drops commercial ads when they stop, BigSpy's free tier limits filters and exports, and Spytrend's free Starter tier only shows ads at least three months old.

What are the best AdSpy alternatives?

On advertiser breadth there is no direct replacement for AdSpy's 30.1 million profiles. By use case the nearest are Spytrend at $79 a month for archive depth and TikTok coverage, BigSpy for a free tier across ten platforms, and PiPiADS at $49 if your traffic is mainly TikTok.

Is the Meta Ad Library the same as a Facebook ad spy tool?

No. The Meta Ad Library is Meta's own free archive of ads running right now, with no spend, run length, performance or targeting, and no history of stopped commercial ads. Paid Facebook ad spy tools are bought for exactly those things.
