Paste your store. We read it live, open the links on your Meta ads and rank your longest-running ad against your category. Free, no sign-up.
From Meta's public Ad Library (US), ads live on Sep 24, 2026. We show no one's ads here, only facts about them and a link to each one. Marketplaces, apps and pharma are left out, and so are ads run from someone else's page and sellers outside the category. Running long means the brand kept paying for the ad. It does not mean the ad made money. A brand that wants its entry taken down can email hello@trycracked.app.
