Open-source, multi-provider AI chat platform unifying OpenAI, Anthropic, Google, Azure, and local models behind one UI, with agents, RAG, code interpreter, and MCP tool support.
Choose LibreChat when you want one chat UI in front of many providers — OpenAI, Anthropic, Google, Azure, and local models — with agents, RAG, a code interpreter, and MCP tools built in. It's the most feature-complete option here and cleanly MIT-licensed, at the cost of being the fiddliest to stand up: it wants MongoDB and a stack of `.env` keys. If you only need a clean front end for one local backend, Open WebUI is far less to wire.
LibreChat's breadth is the draw and the catch — every provider it unifies is one more thing to configure and keep honest:
non-negotiableIt's a real stack, not a single container. LibreChat needs MongoDB alongside it (and a vector store if you want RAG) — budget the 2 GB minimum for the app plus a database to back up, not a one-file deploy.
non-negotiableConfiguration is the work. Multi-provider means a .env full of API keys and a librechat.yaml to shape which models and tools appear — powerful, but plan an evening to wire it correctly the first time.
non-negotiableHosted providers aren't free or private. Point it at OpenAI or Anthropic and you're back to per-token bills and prompts leaving your box — the privacy and cost win only lands when you route it to a local backend.
