Detailed Review
Supabase is not a visual frontend builder, but it belongs in this list because many low-code stacks need a real backend. It gives teams Postgres, authentication, storage, edge functions, and APIs without having to assemble those pieces from scratch.
The key difference from many backend-as-a-service tools is that Supabase keeps the database close to standard Postgres. Teams can write SQL, use extensions, manage row-level security, and grow into more advanced patterns over time.
It pairs well with visual frontend tools such as WeWeb and FlutterFlow. The frontend can move quickly, while Supabase provides a more durable data layer behind it.
Frequently Asked Questions
Is Supabase free?
Supabase offers a very generous free tier, and because it is open-source, you can self-host it entirely for free.
How is it different from Firebase?
Firebase uses a NoSQL document database, which can be hard to query. Supabase uses a relational SQL database (Postgres), which is an industry standard.
Does it have a visual interface?
Yes. Supabase includes a dashboard for managing tables, rows, users, policies, storage, and functions.
