   Supabase

   111.4KstarsLike

   Supabase is an open source backend platform built on Postgres. Each project gets a full Postgres database with auto-generated REST and GraphQL APIs, authentication, file storage, realtime subscriptions, edge functions and vector support for AI applications. It can be used as a hosted service with a free tier or self-hosted with Docker, and appeals to developers who want SQL rather than a NoSQL backend.

   Pros

   • Full Postgres database with SQL, extensions and row-level security
   • Auto-generated APIs, auth, storage and realtime in one platform
   • Open source and self-hostable with Docker

   Cons

   • Free-tier projects are paused after a period of inactivity
   • Self-hosting is more involved to set up than the managed service
   • Row-level security policies take time to get right

   PocketBase

   61.4KstarsLike

   PocketBase is an open source backend that ships as a single Go executable with an embedded SQLite database. It provides realtime subscriptions, user authentication including OAuth2, file storage and an admin dashboard, and can be extended in Go or JavaScript. It suits small projects and prototypes that need a backend running in minutes. It has not reached version 1.0, so breaking changes can still happen.

   • Embedded SQLite with realtime, auth and an admin dashboard
   • Can be extended in Go or JavaScript

   Cons

   • Not yet at version 1.0, so breaking changes can still happen
   • Single-server SQLite design limits horizontal scaling
   • No official managed hosting, so you run and back up the server yourself
