Adspy

AdSpy is a searchable database of Facebook and Instagram ad creatives, with filters for text, advertiser, engagement and time.

Its value over the free official library is the search and filtering: finding ads by keyword in the ad copy, or sorting by engagement, surfaces what is working rather than only what a specific advertiser is running.

As with all ad intelligence, engagement is not profitability — a widely shared ad may be losing money, and the tool cannot tell you which.
