About
Supabase is an open-source backend-as-a-service platform that provides developers with a fully managed PostgreSQL database alongside a suite of backend services—authentication, file storage, edge functions, and real-time subscriptions—through a Firebase-compatible API. Founded in 2020 by Paul Copplestone and Ant Wilson, Supabase chose PostgreSQL as its foundation, betting that developers would prefer a fully relational, SQL-native database over the document-oriented approach of Firebase.
