Supabase

Developer platforms

Build your backend around Postgres.

Supabase starts each project with a full Postgres database and layers integrated application services around it. Generated data APIs, authentication, file storage, realtime channels, Edge Functions, a dashboard, and client libraries share one backend model that teams can use as a managed service, run locally for development, or self-host.

  • A dedicated Postgres database with extensions, backups, generated APIs, and direct database access.
  • Authentication with password, passwordless, OAuth, SSO, JWTs, and Postgres Row Level Security.
  • Integrated storage, Realtime channels, and globally distributed TypeScript Edge Functions.
