Authentication & Identity
733 of the 1,000,000 top sites in our Tranco top-1M census run Supabase (0.1%). An open-source backend-as-a-service platform providing a Postgres database, authentication, and storage APIs. Detection is homepage-level HTML/header fingerprinting, so a site can run Supabase on other pages without it showing here.
