TLDR
AdSpy is a large Facebook and Instagram ad database with the most detailed filters in the category, at $149 a month. No TikTok. Klayson covers Meta too, at a fraction of the price.
Klayson searches the Meta Ad Library by meaning, ranks the top performers first, and answers questions over the ads. Free to search; $29 or $99 a month.
AdSpy wins on filter depth and years of history. Klayson wins on asking, on what the model reads from each creative, and on price.
Neither publishes performance numbers, because Meta does not. Klayson finds the top performers by run time and versions instead.
What each tool is
AdSpy has been the reference Facebook ad database for years: a very large archive of Facebook and Instagram ads with detailed filters (ad text, landing page text, engagement counts as scraped, country, language, gender, age, technology). It is a database with a search form. It costs $149 a month and does not cover TikTok.
Klayson indexes the current Meta Ad Library, reads every creative with a model, and ranks the top performers first by run time and versions. It is built to be asked: "which hooks perform best for meal kits" comes back as a chart with a sample size. It also finds UGC creators and makes ads.

Where AdSpy is better
History and filters. If you need ads from 2021, or every ad whose landing page mentions a specific phrase, or a filter by the technology the landing page runs, AdSpy has spent years building that. Its scraped like and comment counts, while not performance, are a signal Klayson does not collect.
Where Klayson is better
You do not have to know the filter. You say what you mean and get the top performers first, judged by the public signal that tracks results: how long the advertiser kept paying. Then you ask the next question. The model's read of every creative (and the transcript of every watched video) means the search understands "before and after" and "founder on camera". And $29 against $149 is the difference between a tool a solo marketer keeps and one they cancel after a month.
Who should pick which
- Media buyers running many accounts who need deep filters and years of archive: AdSpy.
- Anyone who wants to ask questions and get briefs, or find creators, at a price a small team keeps: Klayson.
