VULK
Native PostgreSQL backend generation — schema, API, auth.
Comparison
AI builders that ship a real PostgreSQL backend (2026)
A frontend-only generator gets you 30% of the way. The other 70% is the database, auth, REST APIs and migrations. These are the AI builders that don't punt that work to a third-party service.

FAQ
Why does this matter?
Supabase is a great service, but locking your backend to it ties you to their pricing tiers, region availability, and product direction. Owning your PostgreSQL schema lets you migrate it to RDS, Neon, Railway, or self-host on day one.
