Supabase

An open-source Postgres database with auth, storage, and instant APIs. The fastest way to add a real backend to a project.

What it is

Postgres plus a generated API, auth, file storage, and row-level security, all behind one dashboard. You get a real SQL database (not a black box) with the glue already built.

When to use it

Almost any app that needs to store data and log users in. It’s the default backend for a small team that wants to move fast without running its own servers.

When NOT to

If you need a specialized data model (heavy graph, time-series at scale) or you’re all-in on a different cloud’s managed stack. For collecting just a handful of rows it can be more than you need, though it’s still the easiest option.

Used in

Powers the database in Build a Waitlist Page and the sessions in Add Authentication.
