The best competitor ad finders, compared.

ViralMojo makes this page, so read it knowing that. ViralMojo is one of the tools on it. We've tried to be straight about where each of the others is the better pick.

Read this if you run a DTC brand and want to see which ads your competitors are running, which of them are working, and what to do with what you find.

See what's winning in your niche

Finding a competitor's ads stopped being hard years ago. Meta's Ad Library shows every Facebook and Instagram ad a brand is running, free, with each start date. Paid tools sit on that kind of public data and sell one of three things: a bigger archive, a way to save and organise what you find, or tracking of chosen brands over time.

So the useful question is what you need after you've seen the ads. A founder checking three rivals weekly, a team keeping a swipe file and a media buyer mining millions of ads need different tools. Seven options follow, free to $175 a month, priced from each vendor's own page today.

Who each tool is for

If you want to remake, not just find

ViralMojo fits DTC merchants who want to turn a competitor's winning ad into their own version; Foreplay and Atria fit teams building a shared library of what they find.

Pick ViralMojo if finding the ad is only step one

You spot a competitor ad that's run for months and want that for your product. Paste your product link: ViralMojo tracks competitors' active Meta ads with days running, adds organic winners from TikTok and Reels, works out why they work, and turns them into your own.

Pick Foreplay, Atria or the free Ad Library if you mainly collect

If the job is a team swipe file, Foreplay (from $59/mo; 4.8/5 from 124 G2 reviews) saves ads from the Ad Library in one click and its Spyder add-on follows named brands. Atria (free plan, paid from $129/mo billed yearly; 5.0/5 from 22 G2 reviews) pairs a followed-brand library with analytics on your own ad account. If you only check a few rivals now and then, Meta's Ad Library is enough.

The tools

Each tool, the same four questions

1. Meta Ad Library

What it does
Meta's own transparency library. Pick a country and All ads, select a brand's Page, and you see every ad it's running across Meta's platforms, with start dates. Ads sharing a creative are grouped, so you can see what a brand has duplicated.
Where it's the better pick
It's the source most paid tools read from, current to the day, and free; start dates show which ads a brand keeps paying for. Outside the EU and UK it only shows running ads, has no spend data for ordinary ads, and sends no alerts — the gap paid tools fill.
Pricing
Free, no account needed to search. (Source: facebook.com/ads/library, October 30, 2026.)
Best for
A first look at any brand, and the place to double-check what a paid tool shows you

2. Foreplay

What it does
Swipe-file software. A Chrome extension saves an ad from the Meta Ad Library in one click; boards and tags organise the saves. Spyder, on the Workflow plan, follows the brands you name and keeps every ad they launch.
Where it's the better pick
When several people need the same saved ad six weeks later, nothing here is as clean, and Spyder keeps a followed brand's killed tests in your archive. G2 reviewers rate Foreplay 4.8/5 across 124 reviews. Ease of use is the strength they mention most.
Pricing
Basic from $59/mo ($49/mo billed yearly), with a 7-day free trial; Spyder brand tracking starts on the Workflow plan at $175/mo ($149/mo billed yearly). (Source: foreplay.co/pricing, October 30, 2026.)
Best for
Teams whose saved ads get lost in screenshots and chat threads

3. Atria

What it does
A searchable ad library and followed competitor brands (50 on Core), combined with creative analytics on your own connected Meta account.
Where it's the better pick
If you spend seriously on Meta, it puts competitor ads and your own results side by side, with a free plan to start. G2 reviewers rate Atria 5.0/5 across 22 reviews.
Pricing
Free plan, no card needed; Core is $129/mo billed yearly (5 seats, 50 followed brands). Higher plans scale with your Meta spend. (Source: tryatria.com/pricing, October 30, 2026.)
Best for
A weekly review that covers your own Meta numbers and what competitors launched

4. BigSpy

What it does
A cross-platform library of 1B+ ads across 11 ad channels, with run dates, engagement and targeting estimates.
Where it's the better pick
When competitors advertise well beyond Meta, with a free tier to try first.
Pricing
Free tier (10 searches a day, Facebook only); Starter $69/mo, or $49/mo billed yearly. All 11 channels come with the top plan. (Source: bigspy.com/pricing, October 30, 2026.)
Best for
Competitors who buy ads beyond Meta, researched on a free tier first

5. Trendtrack

What it does
Ad and Shopify-store intelligence: two to three million new ads indexed every 24 hours, linked to the stores running them. Brandtracker follows named brands (two on Starter).
Where it's the better pick
Freshness, and stores: if you want to see which Shopify stores and products are taking off along with their ads, it covers ground ad-only libraries don't.
Pricing
Starter $49/mo monthly ($41 quarterly, $34 billed yearly); Pro $89/mo; Business $159/mo. (Source: trendtrack.io/pricing, October 30, 2026.)
Best for
Spotting which Shopify stores and products are rising, with the ads behind them

6. AdSpy

What it does
A database of 211M+ Facebook and Instagram ads across 225 countries, filterable by text, advertiser and engagement, with search inside ad comments.
Where it's the better pick
Finding competitors you didn't know about: a filterable archive this size beats searching Page by Page.
Pricing
$149/mo, one plan with near-unlimited usage. (Source: adspy.com, October 30, 2026.)
Best for
Finding advertisers you didn't know about, by searching ad text and comments

7. ViralMojo(our product)

What it does
Paste your product link. ViralMojo tracks competitors' active Meta ads with days running (3, 10 or 20 competitors by plan), adds organic winners from TikTok and Instagram Reels, and works out why the winners win. Then it turns them into your own: a one-click static, an AI video built with an agent (AI UGC style included), their video ad with your product in every frame keeping its hook, pacing and structure, or a real creator who shoots it for you.
Where it's the better pick
When you look at competitor ads to make your next one: a long-runner can become your version the same afternoon.
Pricing
$99, $199 or $399 a month, with the same features on every plan; higher plans add credits, tracked competitors and saved queries. (Source: viralmojo.ai/pricing, October 30, 2026.)
Best for
Merchants who look at competitor ads to decide their next one, and want it made the same day

When to pick something else

When to pick the Ad Library, Foreplay or AdSpy instead

You check three or four rivals once a week: the free Ad Library

If you have a short list of competitors and a few minutes, Meta's Ad Library already shows every ad they're running and when each started. Sort by run time and the long-runners are your shortlist. Pay for a tool when the checking becomes a chore, not before.

Your team shares a swipe file: Foreplay

If three or more people save ads, tag them and brief designers from them, Foreplay's boards and one-click Chrome extension keep everyone's finds in one place, and Spyder saves every ad a followed brand launches, so you don't miss the ones it tests and switches off between visits.

You want to discover advertisers, not just follow them: AdSpy or BigSpy

When you don't yet know who your competitors are, a filterable archive finds every advertiser running ads in your category. AdSpy goes deepest on Facebook and Instagram; BigSpy covers 11 channels with a free tier.

How to choose

Start free. Use Meta's Ad Library for a week on your top three competitors and note what you keep wanting that it doesn't give you. If it's history and alerts, look at Foreplay's Spyder, Atria or Trendtrack. If it's finding advertisers you don't know, look at AdSpy or BigSpy. If it's knowing what to make from what you saw, look at ViralMojo.

Whatever you pick, judge a competitor ad by how long it has run and how often the brand has duplicated it.

FAQ

Common questions.

Search Meta's free Ad Library at facebook.com/ads/library: set the country and All ads, type the brand name and pick its Page from the dropdown. You'll see every Facebook and Instagram ad the brand is running, with the date each started. For Google and YouTube ads, use Google's Ads Transparency Center; for TikTok, TikTok's Creative Center. Treat ads that have run for months, or that the brand has duplicated many times, as the likely winners.

Yes. Meta's Ad Library is free and covers every active Facebook and Instagram ad. BigSpy has a free tier across 11 ad channels, and Atria has a free plan. The free options cover seeing ads; paid plans add history after ads stop, alerts on new launches, team swipe files, or larger archives.

Foreplay's Spyder (from the $175/mo Workflow plan), Atria (followed brands, free plan and paid from $129/mo billed yearly) and Trendtrack follow the brands you choose and save what they launch. ViralMojo tracks 3, 10 or 20 competitors' active Meta ads by plan, with how long each has run.

Make your own version of it. Keep what's likely doing the work — the hook, the structure, the product moment — and change the product, the offer and the proof to yours. ViralMojo does this from your product link: it turns a winning ad into a static ad, an AI video, a version with your product in every frame, or a real creator who shoots it for you.
