The Top 5 Best Free Ad Spy Tools in 2026

You don't need to pay to see your competitors' ads. Meta, TikTok and Google all publish free ad libraries, and they show more than most people realize.

The catch is what they leave out. They show you ads, not which ads are working. They forget most ads once they stop. And none of them tell you when a competitor launches something new.

So which free ad spy tool should you use, and when is a free trial of a paid tool worth it? In this guide we compare the 5 best free ad spy tools of 2026: three free platform libraries and two paid tools you can try for free, with every limit checked on each tool's own site in October 2026.

What makes a free ad spy tool worth using?

An ad spy tool collects the ads other brands are running and makes them searchable. The free ones come straight from the ad platforms, which publish them for transparency. The paid ones build on top of that data.

For most teams the question isn't free versus paid. It's which free source covers your channel, and what you lose by staying free. If you want the full paid lineup, our guide to the best ad spy tools compares 7 of them.

Where free ad spy tools fall short

They don't show what's winning

Free libraries list ads. For most ads they show the creative, the advertiser and when it started running. A brand's biggest winner and its smallest test can look the same.

TikTok's Creative Center is the exception, with reach and CTR sorting, but only for ads advertisers have authorized.

Ads disappear when they stop

The Meta Ad Library holds every active ad, but most ads drop out once they stop running. Only political and issue ads (7 years) and ads that ran in the EU or UK (one year) stay.

That means you can't look back at what a competitor ran last quarter, or how long a winning ad lasted.

No tracking or alerts

None of the free libraries let you follow a brand and get alerted when it launches a new ad. You have to search again, every time, and spot what's new yourself.

That's fine for a one-off look. It breaks down when you're tracking ten competitors every week.

The best free ad spy tools at a glance

Here's how the 5 options compare on what's free, channels and what you give up.

The 5 best free ad spy tools in 2026

Each tool covers a different job. Adspo ranks what competitors are scaling. The Meta, TikTok and Google libraries are the free sources for their own platforms, and PiPiAds is a TikTok-first tool with a free trial.

1. Adspo: the best free trial for seeing what competitors are scaling

Adspo isn't free forever, but its free trial gives you the thing the free libraries can't: which ads a brand is actually putting money behind. It covers 10,000+ verified brands and shows each unique creative once, with its full lifespan, so you're not scrolling through duplicates.

Every creative is ranked by impressions within the brand's own account. Here's a brand page in the Adspo app, with active creatives, ad count and creative velocity in one view.

Sort any brand's ads by longest running to see what it keeps paying for.

Key features:

• Impression ranking. See which creatives a brand is pushing hardest within its own account, not just what it's testing.
• Creative-level tracking. Each unique creative appears once, from launch to turnoff, so nothing is counted twice.
• Full history. Ads stay in Adspo after they stop running, with their runtime, so you can see how long a winner lasted.
• Full context. Hooks, transcripts, ad copy, landing pages and target countries for every ad.
• Unlimited brand tracking. Follow any brand and get alerted when a new ad goes live.
• Boards. Save ads to shared boards your team can brief from.

Pricing and value:

Every plan starts with a 7-day free trial, or 14 days on yearly billing. After that, Adspo costs $29/month, or $19/month billed yearly, with every feature included.

That's the cheapest way to get ranking, history and tracking on top of what the free libraries show. On yearly billing, $19/month is less than PiPiAds' discounted yearly Basic plan at $24.50/month.

Who should use it?

• Creative strategists who brief from proven ads every week.
• Media buyers who want to know what competitors are scaling right now.
• Anyone who has outgrown searching the Meta Ad Library by hand.

Use the trial to answer one question: which of your competitors' ads are winning? Here's how Adspo compares on our ad library alternative page.

2. Meta Ad Library: the best free tool for Facebook and Instagram ads

The Meta Ad Library is Meta's own transparency tool, and it's the source most ad spy tools build on. It contains all active ads shown across Meta technologies, and Meta says anyone can view and search it.

It also keeps ads about social issues, elections or politics for 7 years, and ads that ran in the EU in the past year. New ads appear within 24 hours of their first impression.

Meta Ad Library search page

Key features:

• Search every active ad across Meta's apps, including Facebook and Instagram, by keyword or advertiser.
• Filter by country and ad category.
• Branded content search for paid partnership posts on Facebook and Instagram.
• Spending reports for ads about social issues, elections or politics.

Pricing and value:

• Free. You need to be logged in to Facebook to download searches.

Who should use it?

• Anyone researching Meta ads for the first time.
• Teams that need a quick check on what one competitor is running today.

It's the best free starting point for Meta ads. Our guides on how to use the Facebook Ad Library and how to download ads from it cover it in depth, and our free Facebook Ad Library Downloader extension saves any ad in HD with one click.

3. TikTok Creative Center: the best free TikTok ad spy tool

If you're looking for a free TikTok ad spy tool, start with TikTok's own. The Creative Center's Top Ads page shows "high-performing auction ads on TikTok" and, unlike the other free libraries, lets you sort them by performance.

TikTok Creative Center Top Ads dashboard

Key features:

• Filter by region, industry, objective, time period, ad language, ad format and likes.
• Sort by reach or CTR, not just recency.
• Search by brand or product keyword.
• A Trends section in the same Creative Center.

Pricing and value:

• Free. You need to log in to see all Top Ads.

Who should use it?

• Brands testing TikTok who want to see what top ads in their industry look like.
• Creative teams looking for TikTok-native hooks and formats.

The catch: TikTok says the ads shown are limited to those advertisers have authorized, so it won't show you everything a specific competitor runs.

4. Google Ads Transparency Center: the free way to see Google and YouTube ads

Google's Ads Transparency Center is the free option for everything Meta and TikTok don't cover. Search any advertiser by name or website and you'll see their ads from Search, Play, Maps, Shopping and YouTube.

Ads from verified advertisers stay in the library for one year from the date they were last shown, which is more history than Meta keeps for most ads.

Google Ads Transparency Center search page

Key features:

• Search by advertiser name or website, filtered by country.
• Ads across Search, YouTube, Shopping, Maps and Play in one place.
• Up to 5 common variations of each ad.
• Impression ranges by platform, where available.

Pricing and value:

• Free. Some age-restricted ads need you to sign in.

Who should use it?

• Brands that compete on Google Search and YouTube.
• Anyone checking whether a competitor runs search ads on their brand name.

Two limits to know: impression ranges are only published after a 90-day delay, and Google has permanently removed click-throughs to landing pages.

5. PiPiAds: a free trial for TikTok and Facebook ad search

PiPiAds is a paid ad spy tool built around TikTok, with Facebook and Instagram ads too. It's built for ecommerce, dropshipping, apps and more, and it has a free trial you can start without picking a plan.

PiPiAds homepage

Key features:

• Search TikTok, Facebook and Instagram ads by keyword, product, store or URL.
• Rankings of top products, new products, stores and apps.
• TikTok Shop research.
• Ad trackers on paid plans (2 on Basic, 10 on Advanced).

Pricing and value:

• Free trial: 500 credits for ad search, 1 user, no ad details.
• Basic: $49/month on a flash sale (list $69), or $24.50/month billed yearly ($294/year) on a 50% off Q4 offer that runs until December 31, 2026. 30,000 credits a month.
• Advanced: $99/month on a flash sale (list $159), or $49.50/month billed yearly. 100,000 credits a month.

PiPiAds runs on credits: each ad returned in a search costs 1 credit and opening an ad's details costs 20.

Who should use it?

• TikTok-first sellers who want more than the Creative Center shows.
• Dropshippers researching products through ads.

The free trial is enough to test the search, but without ad details you won't see much beyond the creative. More on how it stacks up in our BigSpy alternatives guide.

Key criteria when choosing a free ad spy tool

You're not just picking a free tool. You're picking how much time you'll spend digging for signal.

Channel coverage

Start with where your competitors advertise. Meta's library for Facebook and Instagram, TikTok's Creative Center for TikTok, Google's Transparency Center for Search and YouTube. No single free tool covers all three.

Ranking

A list of 500 ads isn't useful if you can't tell which ones matter. Look for a way to see what a brand is pushing. Adspo ranks every creative by impressions within the brand's own account.

History

Winning ads are the ones that run for months. A tool that drops ads when they stop can't show you that. Adspo keeps every creative with its full runtime.

Tracking

Competitor research is weekly work, not a one-off. If you're searching the same brands every Monday, brand tracking and alerts will save you hours. Adspo includes unlimited brand tracking on every plan.

Final verdict: which free ad spy tool is right for you?

• Most brands and creative teams: Start with the Meta Ad Library, then try Adspo free for 7 days to see which competitor ads are winning.
• TikTok advertisers: The TikTok Creative Center first. PiPiAds' trial if you need more search.
• Search and YouTube advertisers: The Google Ads Transparency Center.
• Ecommerce and dropshipping sellers: PiPiAds, for product and store research alongside ads.
• Agencies tracking many brands: Adspo, because brand tracking and shared boards matter more than any single search.

For most teams, the answer is simple. Use the free libraries for a quick look, and use Adspo when you need to know what's actually working.

Wrapping it up

The free ad libraries from Meta, TikTok and Google show you what competitors are running. They don't show what's winning, they forget most ads, and they won't tell you when something new launches.

With Adspo you get:

• Every active creative for 10,000+ verified brands, shown once.
• Impression ranking within each brand's account, plus runtime for every ad.
• Hooks, transcripts, landing pages and target countries.
• Unlimited brand tracking and shareable boards.

Try Adspo free for 7 days and see what your competitors are scaling this week.
