Supabase is an open source Firebase alternative. Start your project with a Postgres database, Authentication, instant APIs, Edge Functions, and Realtime subscriptions.
Overview
Supabase is an open-source Firebase alternative built around PostgreSQL. Every project is a full Postgres database with instant auto-generated APIs, authentication, file storage, edge functions and realtime subscriptions — all from one dashboard. Because it is plain Postgres, you keep SQL, extensions and full ownership of your data.
The free tier includes a 500MB database, 1GB file storage, 2GB bandwidth, up to 50,000 monthly active users for auth, and unlimited API requests. Inactive free projects may be paused after a period without activity, then restored on demand.
It is ideal as the back end for web and mobile apps that need auth, a relational database and realtime features without running servers — with a clean upgrade path, since it is standard PostgreSQL underneath. Always confirm the current free-tier limits on the provider’s site.
