A cross-platform ad library with a free Facebook tier.

Our verdict
BigSpy is the pick if you want the cheapest, widest ad library for creative inspiration across many platforms, as long as you start on the free plan, treat its metrics as directional, and set a reminder before any renewal.
BigSpy turns up in every "best ad spy tool" list, usually with an affiliate link attached, so the first fair question is whether it is a real product or a marketing push. It is real. BigSpy launched in 2018. Its library holds more than a billion cataloged creatives across 11 ad channels, and it has a large paying user base. People regret it when they expected hard competitive data, or when a renewal date slipped past them.
BigSpy is a cross-platform ad library. It pulls ads from Facebook, Instagram, TikTok, YouTube, Google, X, Pinterest, Yahoo, Unity, Pangle and AppLovin into one searchable database, then layers on filters, creative downloads, landing-page capture and page tracking. Breadth is its real edge over the other tools we rank. AdSpy goes far deeper on Facebook and Instagram but covers nothing else. Anstrex owns native and push networks. Foreplay is a creative workflow tool for saving and briefing ads, and Minea ties ecommerce product data to its ad feed. BigSpy is the one that spans the most surfaces for the least money.
Day to day, that is what buyers like. It is cheap, it has a free plan with no paid subscription required, and it is faster than clicking through the Facebook Ad Library and TikTok Creative Center by hand. Media buyers use it to build swipe files: hooks, first frames, offers, UGC formats and competitor creative volume across platforms a single-network tool would miss. As one buyer put it, "sometimes you find gold."
Buyers who regret the purchase point to two things. The first is data accuracy. Users report impression figures that repeat suspiciously. The same round numbers show up on many different ads, so the metrics are directional at best. The interface feels dated and search is hit or miss, so you spend real time sorting through low-quality results. Use what BigSpy surfaces as a starting point, then check it in the live ad library. No ad-spy tool can show you whether an ad is profitable.
The second, and the loudest complaint by far, is billing. BigSpy renews each subscription until you cancel. A full refund is available within 24 hours of the first payment, and also when a system bug is at fault. After that window, you keep access until the paid period ends. Renewals are non-refundable.
The third thing to know is what the price actually buys. BigSpy advertises 11 platforms, and Ultimate is the plan that carries all of them. Starter covers Facebook and Instagram, with AppLovin only for ecommerce ads, and only for a limited time. TikTok, YouTube and Google are included on Growth. Free access is Facebook only. Search caps, yearly bills and the seat count are on our BigSpy pricing page.
Who should buy it: a media buyer or ecommerce seller who wants the widest, cheapest net for creative inspiration and will validate anything they find. Look elsewhere when you need spend or impression numbers you can trust. AdSpy is the sharper Meta tool for that, and a native or push buyer needs Anstrex. BigSpy ranks fifth in our ad-spy category for that reason. It is the broadest and cheapest tool here, and its numbers are the roughest. If BigSpy is the wrong fit, the alternatives page lists the other ad libraries.
Mostly praised by buyers
Media buyers describe BigSpy as a low-cost, wide net for finding hooks, angles and creative formats across many platforms. The value is breadth at a low entry price, not depth.
“BigSpy - Cheap. Interface looks like it's from 2015 but whatever, it works. Search can be hit or miss - sometimes you find gold, sometimes you wade through garbage for 20 minutes.”

“Bigspy also has some issues… all the ad impressions are either 4.2k or 8.4k… This makes me think that the data is not accurate, or at least it's not being presented correctly.”
Experienced buyers warn that no ad-spy tool proves an ad is profitable. Longevity and repeated variations are clues to validate, not ROAS you can bank on.

A common complaint
Buyers write about charges that arrived after a trial. The vendor says it does not issue refunds once the order is completed and delivered.
“dont try BIGSPY they said try 3 days for 1$ but they get my money for 99$ BIGSPY IS SCAM”
“As a SaaS provider, all products and services offered by BigSpy and its business units are non-tangible and irrevocable, so we do not issue refunds once the order is completed and delivered.”
The pricing page offers a free start with no paid subscription required. Yearly charges printed there are $588, $1,428, $3,588 and $4,788. Scale is listed as 5 seats, 1 owner and 4 members.
“Explore Facebook ad creatives, try AI tools and track your first creatives. No paid subscription required.”
“$588 billed annually”
“$1,428 billed annually”
“$3,588 billed annually”
“$4,788 billed annually”
“5 seats · 1 owner + 4 members”
