butterbase-ai/butterbase-oss

Butterbase bundles the table-stakes BaaS primitives — Postgres, auth, file storage, edge functions — and adds two things that set it apart from the obvious comparison: a built-in AI gateway and MCP support. The AI gateway means you are not manually wiring your backend to OpenAI or Anthropic endpoints per-project; it is a first-class layer. MCP support means the context protocol is baked in rather than a weekend hack on top. For a solo founder building an AI-native SaaS who is tired of assembling these pieces separately, that is a real time save. Reservation: the repo is freshly open-sourced, which means the documentation and self-hosting story will have rough edges. The Supabase comparison is inevitable and Supabase has years of production hardening; bet on butterbase for greenfield AI-native projects rather than anything requiring a battle-tested auth layer on day one. -> Best for: solo founder or indie hacker building an AI-native SaaS who wants BaaS primitives and AI gateway in one repo
