An open source Firebase alternative built on PostgreSQL featuring managed databases authentication row level security and edge functions.
About Supabase
Supabase is an open source backend as a service platform designed as a developer friendly alternative to Firebase. Built on top of a fully managed PostgreSQL database, it provides engineering teams with the foundational building blocks required to launch modern web and mobile applications rapidly. By combining relational database primitives with instant REST and GraphQL APIs, Supabase eliminates the need to build custom server infrastructure from scratch.
The platform provides a cohesive suite of developer tools including robust user authentication, globally distributed serverless edge functions, real-time data synchronization via WebSockets, and scalable object storage. Furthermore, Supabase integrates native vector database capabilities through the pgvector extension, empowering developers to build retrieval augmented generation applications and AI powered features directly on their relational data layer.
Organizations can choose between fully managed cloud hosting tiers with automated backups and scaling or self-hosting the entire stack using Docker for strict data residency and compliance requirements. This architectural flexibility makes Supabase suitable for indie developers prototyping MVPs as well as enterprise engineering teams building scalable production workloads.
