What their homepage claims
“Supabase | The Postgres Development Platform”
What that means
They provide a backend services stack for applications built on PostgreSQL, including authentication, serverless functions, storage, real-time data, and REST APIs.
Verdict
The homepage uses a platform-centered headline and lists multiple concrete features, but it does not present a single concrete product category in the headline; overall, the writing leans on abstractions and could be clearer about what is being sold.
Evidence
