supabase

Postgres backend with auth, storage, realtime and edge functions

111.3k stars, Apache-2.0, last commit Oct 2026

Supabase bundles a Postgres database with generated REST and GraphQL APIs, JWT-based auth, S3-backed file storage, realtime change feeds over websockets, and edge functions. It also includes a vector and embeddings toolkit for AI workloads. It runs as a hosted platform, can be self-hosted, or run locally, and has official clients for JavaScript, Flutter, Swift and Python.

Strengths

  • Built on Postgres, PostgREST, GoTrue and Realtime, so the data layer is plain SQL
  • Official clients for JavaScript/TypeScript, Flutter, Swift and Python
  • Hosted, self-hosted and local development options
  • Apache-2.0 license; vector and embeddings toolkit included

Weaknesses

  • Many separate services to run when self-hosting; README gives no resource requirements
  • Go, Java, Rust, Ruby and C# clients are community-maintained, some partial
  • Repo has no Docker or compose files; self-hosting is documented elsewhere
  • no GPU
  • Compose
  • Needs PostgreSQL, S3-compatible storage, Envoy

graphql-engine

GraphQL API layer over Postgres, MongoDB, ClickHouse and SQL Server

32.1k stars, Apache-2.0, last commit Oct 2026

Hasura GraphQL Engine exposes data from PostgreSQL and its flavors, MongoDB, ClickHouse and MS SQL Server through a single GraphQL endpoint. Custom business logic can be added with TypeScript, Python and Go connector SDKs. The repo is a mono-repo holding the V3 engine (which powers Hasura DDN) and the stable V2 engine, with all data connectors open source.

Strengths

  • Supports PostgreSQL, MongoDB, ClickHouse and MS SQL Server as data sources
  • Connector SDKs in TypeScript, Python and Go for custom logic
  • Core engines and data connectors are Apache-2.0 licensed
  • V2 remains available as the current stable version

Weaknesses

  • Large mono-repo with long history; README recommends shallow or sparse clones
  • V2 and V3 are separate codebases with separate docs
  • V3 is documented around the hosted Hasura DDN workflow
  • README lists no RAM, port or AI model details
  • no GPU
  • Compose
  • Needs PostgreSQL, MongoDB, ClickHouse, MS SQL Server
