Butterbase is an open-source, AI-native backend-as-a-service platform built on Postgres, providing auth, storage, serverless functions, an LLM gateway, realtime subscriptions, and a built-in MCP server. It is a self-hostable Supabase alternative designed so AI agents can operate the backend via MCP tools.

Use cases

• self-host a supabase alternative
• add auth and row-level security to a postgres backend
• let AI agents manage my backend via MCP
• build an AI app with an LLM gateway and RAG
• get automatic REST APIs from a postgres schema
• store files and key-value data for my app
• run serverless functions without vendor lock-in

When to choose

• you want an open-source, self-hostable Supabase alternative
• you're building AI-driven apps that need an LLM gateway, RAG, or MCP tool access
• you want Postgres with managed auth, RLS, storage, and auto-generated REST APIs in one stack

When to avoid

• you need a battle-tested BaaS with a large ecosystem and managed hosting at scale
• you only need a plain database or a single-purpose service rather than a full platform
• your stack is not TypeScript/Postgres oriented
