The short answer
The best free ad spy tool for Facebook and Instagram is the Meta Ad Library, and TikTok, Google and LinkedIn each run their own free library too. Paid tools add free plans or 7-day trials, but none of the free options shows estimated spend, filters for winners or tags ads. That matters because on our board the top 10% of ads carry 57% of the estimated spend: without a spend signal you study the wrong ads.

The short answer
A free ad spy tool exists for every major ad platform, and the platforms built them themselves. Meta, TikTok, Google and LinkedIn each publish a searchable library of the ads running on their networks. On top of that, most paid tools now offer a free plan or a 7-day trial, so you can test them before you pay.
What free gets you is the ads. What it doesn't get you is the ranking: which of a competitor's 40 live ads has the money behind it. This article covers both sides, with every price and limit checked on the vendors' own pages on October 12, 2026. If you already know you will pay and want the full comparison, read the best ad spy tools instead.
The four official libraries
These are the free ad spy tools that cost nothing forever, because the platforms run them for transparency.
| Library | Platforms | What you see | What you don't |
|---|---|---|---|
| Meta Ad Library | Facebook, Instagram, Messenger, Audience Network, WhatsApp | Every active ad, start date, versions, platforms | Spend and impressions for commercial ads |
| TikTok Creative Center (Top Ads) | TikTok | A curated set of high-performing auction ads, with likes | Ads from a brand you pick, if TikTok hasn't featured them |
| Google Ads Transparency Center | Search, Display, Gmail, YouTube | Ads an advertiser served, by date and region | Spend, except on election ads |
| LinkedIn Ad Library | Ads since June 2023, advertiser and payer | Impressions and targeting, except for EU-targeted ads |
Meta Ad Library
The one most people mean by a free Facebook ad spy tool. It holds every active ad on Meta's platforms for any advertiser, with the creative, copy, start date and how many versions share it. Per Meta's Ad Library tools page, spend, reach and funding details are shown only for ads about social issues, elections or politics, and EU-delivered ads get extra reach data. Since December 22, 2025 it also flags ads with fewer than 100 impressions as "Low impression count" (PPC Land), and since early 2026 it can sort results by impressions, though it still shows no numbers. Our guide to the Meta Ad Library walks through every filter.
TikTok Creative Center
TikTok's Top Ads page shows "high-performing auction ads on TikTok", with filters for region, objective, ad language, format and likes, and sorting by reach or CTR. It is closer to a spy tool than the others because TikTok pre-selects the winners. The catch is that TikTok picks the ads, not you: it is an inspiration feed, not a way to see every ad a named competitor runs.
Google Ads Transparency Center
Google's repository covers ads served on Search, Display, Gmail and YouTube. You search by advertiser or website and filter by date and targeted location. For ads served in certain regions, Google adds targeting information and the total number of recipients, and election ads carry extra disclosures (Google Ads help). Useful for seeing which search and YouTube ads a brand runs alongside Meta.
LinkedIn Ad Library
LinkedIn's library includes ads that ran after June 1, 2023 and keeps them for one year after their last impression (LinkedIn Help). For ads targeted in the European Union it also shows run dates, the targeting the advertiser chose, and estimated total impressions with a breakdown by country (LinkedIn Help). For B2B it is the best free source there is.
Free plans and trials of paid tools
The second kind of free ad spy tool is a paid tool's entry door. We checked each pricing page on October 12, 2026.
| Tool | Free option | Limits | First paid plan |
|---|---|---|---|
| BigSpy | Free plan | Facebook only, 5 searches and 20 creative downloads a day | Starter, $69/month (pricing) |
| Atria | Free plan since June 2026 | One ad account, one brand, limits not published | Core, $129/month billed annually (pricing) |
| GetHookd | 7-day trial for $0 | Cancel before day 7 and you pay nothing | Starter, $29/month or $19 billed yearly; on its second price list, Pro at $49 or $32 billed yearly |
| Foreplay | 7-day trial | Card required, 14-day money-back after the first charge | Basic, $59/month |
| PiPiAds | Free trial credits | 500 credits, some features limited, no refunds after you subscribe | Basic, $49/month |
| AdSpy | None listed | No free plan or trial on its site | $149/month |
A few honest notes on this table:
- BigSpy's free plan has no time limit and publishes its limits. Five searches a day is enough to check a few competitors weekly. It is not enough to browse a niche.
- Atria's free plan is permanent, not a trial, but Atria says it deliberately doesn't publish the exact limits because they change. It suits a single brand that also wants analytics on its own ad account.
- GetHookd's trial is the cleanest way to try a large live Meta library for a week without paying. We compare it with Ad Radar in Ad Radar vs GetHookd.
- AdSpy has no free door. If you are asking "is AdSpy free", the answer is no; our AdSpy alternatives cover what you get elsewhere for less.
Where free ad spy tools stop
Every option above shows you ads. None of them, free tier or trial, answers the question you actually open a spy tool for: which of these ads is a winner? Three things are missing.
1. No spend
Meta does not publish spend for commercial ads, so no free library can show it. The closest free signals are days live and version count, and both mislead. On our board, for 41 of the 47 brands with ten or more winning ads, the oldest ad is not the one with the most estimated spend. Estimating competitor ad spend covers the free methods and where each breaks.
2. No filter for winners
A free library shows tests and winners side by side. The low impression count label only removes ads under 100 impressions, which is a test that never got a budget, not a loser that spent $20K. The gap between the two is wide:
2,443
ads on our board, each with $50K+ estimated spend
$223K
median estimated spend per ad
$1.07M
90th percentile
57%
of total estimated spend in the top 10% of ads
Those numbers come from our October 9, 2026 snapshot of 749 brands. Even among ads that already cleared $50K, the money is concentrated in a small share. In a free library, where most ads never reach $50K, the ratio of noise to signal is far worse.
3. No tags
Free libraries let you search text. They don't tell you that an ad is a problem-aware first-person story sending traffic to a listicle. Without tags you can't ask "show me every winning founder ad in skincare", and you rebuild the same spreadsheet each week.
Two ads from the board show what the missing signals hide:
New Launch!
- Est. spend
- $7.3M
- Days live
- 59
- Format
- Image
- Variants
- 4
Two words and a product shot, under two months old. Sorted by start date in a free library, it sits below hundreds of older ads from the same niche.
Airport thieves are now stealing your stuff with just a pen.
- Est. spend
- $5.2M
- Days live
- 882
- Format
- Video, 45s
Almost two and a half years on one opening line. Days live would have found this one for free. It would not have told you the 59-day Kitsch ad carries more.
Where Ad Radar fits
Ad Radar is our product, so weigh this section accordingly. It starts where the free tools stop, for Meta only.
- The Chrome extension is free to install from the Chrome Web Store. It adds a Save button to every ad in the Meta Ad Library, from any brand, and copies the media before Facebook's links expire. Saved ads land in your boards with a transcript, tags and a swipe prompt. It works with an Ad Radar membership.
- The membership is $49 every 4 weeks at the launch price (list $99). It gives you the board: only Meta ads with $50K or more in estimated spend, each tagged on ten dimensions (hook pattern, hook mechanism, angle, awareness, proof, format, video type, landing page type, niche and CTA), with search across headlines, copy and video transcripts.
- Follow any brand by pasting its Ad Library link, and get an alert when one of its ads turns into a winner.
What it doesn't do: TikTok, Google or LinkedIn, and it doesn't connect to your ad account. If you need those, the free libraries above and the trials of multi-platform tools are the better start. The full feature list is on the features page.
A free-first routine
You can run real competitor research for $0. Pay only when the free steps become the bottleneck.
- Pick five competitors and search each one in the Meta Ad Library, active ads only, with the country set to the US.
- Skip anything labeled low impression count and note start date and version count for the rest.
- Check the other platforms once a month: Google's center for search and YouTube, TikTok's Top Ads for your category, LinkedIn if you sell B2B.
- Click through every landing page of an ad live 60 days or more. The destination often explains the ad.
- Upgrade when ranking is the problem. When you have 40 candidate ads and no way to tell which one carries the budget, a spend signal pays for itself. Until then, the free tools are enough.
