Supabase is an open-source Firebase alternative that provides a PostgreSQL database, authentication, instant APIs, real-time subscriptions, and storage. Build your backend in minutes, not months.
Supabase is an open-source backend-as-a-service (BaaS) platform that provides a full-featured PostgreSQL database with real-time capabilities, authentication, storage, and edge functions. It's designed to be a drop-in replacement for Firebase but with the power and reliability of PostgreSQL.
Supabase was founded in 2020 by Paul Copplestone and Ant Wilson. It quickly gained popularity as developers sought an open-source alternative to Firebase with PostgreSQL at its core.
Supabase has over 100,000 active projects and 4 million GitHub stars. It's the fastest-growing open-source backend platform.
Built on PostgreSQL, Supabase adds RESTful APIs via PostgREST, real-time via Realtime server, authentication via GoTrue, and storage via S3-compatible API.
