Open-source Firebase alternative with PostgreSQL at its core.
Supabase is an open-source backend-as-a-service built on top of PostgreSQL. It provides a complete backend with authentication, a real-time database, file storage, edge functions, and auto-generated APIs — all from a single platform. Supabase is the fastest-growing open-source Firebase alternative.
Unlike Firebase, Supabase uses PostgreSQL (the most advanced open-source database) instead of a proprietary NoSQL database. This means you get SQL queries, joins, foreign keys, and the entire PostgreSQL ecosystem while still having real-time subscriptions and simple client libraries.
Supabase's Row Level Security (RLS) policies provide fine-grained access control at the database level, while its auto-generated REST and GraphQL APIs eliminate the need to build a custom API layer for most use cases.
Supabase is our recommended backend platform for most new projects. It provides authentication, database, storage, and real-time capabilities out of the box, allowing us to focus on building features instead of backend infrastructure.
Supabase's PostgreSQL foundation means no vendor lock-in — you can export your data and move to any PostgreSQL host at any time. Its excellent Next.js integration with server-side auth helpers makes it a natural fit for our stack.
