Supabase
An open-source Firebase alternative on Postgres.
About
A backend platform built on plain Postgres - database, authentication, storage, realtime and edge functions behind one API. Open source, with a usable free tier and predictable paid plans as you grow.
Pros
- Real Postgres you can query and own, not a proprietary store
- Auth, storage, realtime and edge functions included
- Open source with a generous free tier
Cons
- You still manage schema, RLS and migrations yourself
- Some features are newer than long-established incumbents
What it solves
Standing up auth, a database, file storage and APIs separately eats weeks. Supabase gives you all of it on real Postgres from day one.
When not to use it
Less suited if you need a non-relational data model, or want a fully managed enterprise database with hands-off ops.
