Quick Analysis
Supabase is an open-source backend-as-a-service platform, competing with Firebase, AWS Amplify, and PlanetScale in the application backend space. Built on PostgreSQL, it provides a managed database, authentication, real-time subscriptions, object storage, edge functions, and auto-generated REST/GraphQL APIs — offering Firebase-like developer productivity with the power of a relational database.
Supabase's strength is its PostgreSQL foundation — developers get a real relational database with SQL, joins, transactions, and extensions (pgvector for AI, PostGIS for geospatial) while benefiting from Firebase-like convenience. It is ideal for startups and modern app teams who want rapid development without sacrificing data flexibility. Compared to Firebase (mature mobile SDKs, proprietary NoSQL), Supabase offers SQL and open-source freedom. Versus PlanetScale (MySQL-based, horizontal scaling), Supabase provides a broader feature set beyond the database.
Buyers should choose Supabase for new applications wanting PostgreSQL with a modern developer experience. The free tier is generous for prototyping. Consider Firebase for established mobile SDK needs, or AWS Amplify for teams deeply invested in AWS services.

Checked and not offered
One capability that other operational database tools are built around, which Supabase does not appear to cover. Each was checked against Supabase's own documentation in three separate AI passes, and only a majority verdict is recorded — the count is on each row.
A gap is not a fault — a product that does one job well is a reasonable thing to buy. It is only expensive when you find out after signing.
