Supabase
Open-source Postgres backend with auth, storage, realtime, and edge functions.
About
Supabase is the open-source Firebase alternative built on real PostgreSQL. It gives developers a hosted Postgres database plus authentication, S3-compatible storage, realtime subscriptions, edge functions, and pgvector, all behind auto-generated REST and GraphQL APIs. Because it is genuine Postgres, data stays portable and standard SQL applies, and the core can be self-hosted.
Supabase became the default backend of the vibe-coding era: in June 2026 it raised a $500M Series F at a $10.5B valuation led by GIC, reporting that database launches grew 600% year over year and that more than 60% of new databases were created by AI tools like Claude Code and Codex. Tools including Bolt, Lovable, Cursor, and Replit provision Supabase automatically. The free tier (500MB database, 50K monthly active users) mirrors the project's own infrastructure constraints, and HIPAA compliance requires Team tier or above.
