The honest call
Which one should you pick?
There is no winner for everyone. Here is where PrimDB fits and where Supabase is the better choice.
When PrimDB fits
- You want to deploy your whole app, not just a Postgres backend and edge functions.
- You want managed Redis and a dedicated full-text search engine alongside your database.
- You want approval-gated previews with a stakeholder feedback overlay and a native MCP endpoint for agents.
- You want deploy, data, and auth behind one API rather than assembling a backend around Postgres.
When Supabase fits
- You want a mature, open-source Postgres backend with realtime and row-level security, backed by a large community.
- You want the option to self-host or move off the platform because it is open source.
- Your app is Postgres-centric and you do not need a general deploy host for arbitrary services.
FAQ
PrimDB vs Supabase, answered

- Partly. Like Supabase, PrimDB gives you managed Postgres, auth, and storage. Unlike Supabase, PrimDB also deploys your whole app, adds managed Redis and a dedicated search engine, and exposes a native MCP endpoint for agents. Supabase centers on Postgres; PrimDB centers on deploy plus the full data and auth layer.
- Is PrimDB open source and self-hostable like Supabase?
- No. Supabase is open source and can be self-hosted. PrimDB is a hosted platform run on Hetzner in the EU. If open source or self-hosting is a hard requirement, Supabase fits better.
