Our top 3 Supabase (hosted) alternatives
Supabase is a combination of enterprise-grade open source tools assembled into a single backend platform. The project describes its goal as building the features of Firebase using open source products: where an MIT, Apache 2, or equivalent licence exists in the ecosystem, Supabase adopts and supports that tool, and where one does not exist, the project builds and open sources it. The stack is written primarily in TypeScript and lives in the Postgres and JavaScript ecosystem, with modular client libraries implemented per language.

PocketBase is an open-source backend framework written in Go that bundles a SQLite database, authentication, file storage, admin dashboard, and REST API into a single executable file. It lives in the Go ecosystem and targets developers who want a lightweight, self-contained backend without managing separate services like PostgreSQL, Redis, or a separate auth server.

It runs as a self-hosted service or via a managed cloud offering (Appwrite Cloud), targeting developers who want to avoid assembling and maintaining disparate backend tools.
