Supabase
Open-source Firebase alternative built on Postgres.
About Supabase
Supabase is an open-source Firebase alternative built on PostgreSQL, available as a managed cloud service or self-hosted via Docker. It provides a fully managed Postgres database, authentication with multiple OAuth providers, auto-generated REST and GraphQL APIs, edge functions (Deno), real-time subscriptions, and file storage — all accessible from a clean dashboard or via client libraries for JavaScript, Python, and other languages. The free tier includes two projects with 500 MB database storage. Supabase is widely used by indie developers and startups who want a complete backend-as-a-service without vendor lock-in to a proprietary database, and who need auth and storage without building those layers from scratch.
