When a PHP Backend Can Replace Your Supabase Use
A smaller application backend for a narrower set of needs.
What you get
If you need account sign-in, per-user records, billing and admin, the Simple Stack PHP backend may cover your product with a single application and a SQLite database. Access rules live in the PHP handlers and queries, so new endpoints must enforce ownership explicitly.
The tradeoffs
Supabase can also be self-hosted; describing it as managed-only would be wrong. It offers a different collection of Postgres-based services. Simple Stack is not a drop-in replacement for Postgres row-level security, realtime subscriptions or every Supabase API.
What to try first
Inventory the features your app actually calls before migrating. Build one resource against the PHP API, test ownership and estimate operational work. Keep Supabase if its services are central to the product or its managed offering is worth more to you than maintaining the server.
Try before choosing
The live demos use sample data and simulated payments. The download includes the source and setup guides; your own launch still needs provider configuration and end-to-end testing.
