Supabase provides a PostgreSQL database with auto-generated APIs, real-time subscriptions, authentication, and storage out of the box.
Supabase gives developers a complete backend in minutes by wrapping PostgreSQL with auto-generated REST and GraphQL APIs, real-time websocket subscriptions, built-in authentication, and file storage. It is often described as the open-source alternative to Firebase, but with the full power of PostgreSQL underneath. This means you get relational data modeling, joins, and SQL while also getting the developer experience of a backend-as-a-service. Supabase is particularly popular for MVPs and side projects where speed of development matters, but its PostgreSQL foundation means applications can scale to production workloads without migrating to a different database.
