Supabase is an open-source alternative to Firebase built on PostgreSQL. It provides a hosted database with a REST and GraphQL API, user authentication, file storage, edge functions, and real-time subscriptions. Unlike Firebase (which uses a NoSQL document database), Supabase uses PostgreSQL — a full-featured relational database with SQL, joins, transactions, and row-level security. The free tier includes 500MB database, 1GB file storage, and 50K monthly active users.
