About Supabase
Supabase is an open source Firebase alternative that provides a complete backend platform built on PostgreSQL. In minutes, you get a hosted Postgres database, authentication, file storage, real-time subscriptions, and edge functions — all with a generous free tier.
Unlike Firebase (a NoSQL document database), Supabase uses PostgreSQL — a relational database with full SQL support, row-level security, stored procedures, and foreign keys. This makes it suitable for applications where data relationships and integrity matter.
Supabase Auth supports email/password, magic links, and 20+ OAuth providers. Storage handles file uploads with access control. Realtime lets you subscribe to database changes with WebSockets. Edge Functions are Deno-based serverless functions deployed globally.
The Supabase Studio dashboard provides a table editor, SQL editor, API docs, logs, and more. It can be self-hosted, making deployment to your own infrastructure possible.
