You can run Postgres yourself, but Supabase's value is the integrated auth, realtime, storage, and auto-generated APIs. Self-hosting Supabase is possible but complex.
Key Considerations
- •Raw Postgres is easy to set up on any cloud
- •Realtime subscriptions require additional infrastructure
- •Auto-generated REST/GraphQL APIs save significant time
- •Self-hosting Supabase is officially supported but complex
