GP: to save you a click, we're an "open source firebase alternative" but it might be simpler to think of us as an easy way to use Postgres.

We give you a full PG database for every project and auto-generated APIs using PostgREST [0]. We configure everything in your project so that it's easy to use Postgres Row Level Security.

We provide a few additional services that you typically need when building a product - connection pooling (pgbouncer), object storage, authentication + user management, dashboards, reports, etc. You don't need to use all of these - you can just use us as a "DBaaS" too.
