What is Supabase?

Supabase is an open-source backend-as-a-service built on Postgres, often described as the open alternative to Firebase. Every project gets a full Postgres database plus the services most apps need around it: authentication with row-level security, instantly generated REST and GraphQL APIs, realtime subscriptions, file storage, edge functions, and vector embeddings for AI features. The dashboard's table editor and SQL console make the database approachable, while everything remains standard Postgres underneath — no proprietary data model to outgrow. Client SDKs for JavaScript, Flutter, Swift, and more make it the default backend for many indie and startup web apps. The platform's core is open source and self-hostable, and the hosted free tier comfortably runs small production projects before usage-based paid plans kick in.
