Supabase Freemium

Supabase is an open-source backend platform that gives developers a Postgres database, authentication, file storage, and edge functions in one product. Often described as an alternative to Firebase, it adds realtime subscriptions and a rich REST and GraphQL API while keeping the full power of a relational database underneath. AI teams use it as the data and auth foundation for apps that pair LLM features with transactional state.

Because Supabase is built on Postgres, it supports full-text search, PostGIS, and a growing ecosystem of AI extensions such as pgvector for storing embeddings. Combined with Row Level Security and built-in authentication, developers can ship a production backend quickly. The platform offers both hosted cloud and self-hosted open-source options, making it a flexible foundation for everything from MVPs to large-scale applications.
