Our takeA popular backend for vibe coders: Postgres, auth, storage and realtime in one place, supported by many AI app builders. Free projects pause after a week of inactivity.Serverless Postgres with autoscaling and instant branching, billed purely by usage with no monthly minimum. Ideal when you only need a database, not a full backend.A reactive backend where your database queries and server functions are TypeScript, with realtime updates built in. Very AI-agent friendly; a different model from SQL.
