Postgres · Auth · Storage · Functions · AI Gateway · MCP server Website · Discord · LinkedIn · Self-host · Docs · Roadmap · Examples · Contributing --- Butterbase gives you the building blocks for AI-driven applications without lock-in: a Postgres-backed backend with row-level security, serverless functions, an LLM gateway, realtime subscriptions, key-value store, file storage, RAG, durable per-key actors, and a built-in Model Context Protocol (MCP) server so agents can operate your backend with tools instead of glue code. Features Data - Postgres data plane — per-app databases with declarative schema ( /schema ), automatic REST endpoints ( /auto-api ), and migrations. - Row-Level Security — first-class RLS policy management with user-isolation helpers ( /rls ). - Key-Value store — regional, quota-protected KV with TTL, audit trail, and dashboard expose rules ( /v1/:app/kv/ ). New in v0.2.0. - File storage — S3/R2-backed object storage with presigned URLs, ACLs, and async indexing ( /storage ). Compute - Serverless functions — TypeScript functions executed on the Deno runtime ( /functions ). - Durable Objects — stateful per-key actors for chat rooms, multiplayer, rate limiters, long-running agents ( /durable-objects ). - Realtime — WebSocket subscriptions to table changes for live UIs and presence ( /realtime ). - Edge SSR — deploy Next.js / Remix / Astro edge handlers from source ( /edge-ssr , /edge-ssr-from-source ). - Frontend h","default_branch":null,"files":null,"tree":[],"storefront":"/r/butterbase-ai","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/butterbase-ai/butterbase/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
