What Is LibreChat?

LibreChat is an open-source, customizable artificial intelligence chat interface that brings the familiar design of ChatGPT to a self-hosted, multi-model environment. With support for OpenAI, Anthropic Claude, Google Gemini, Groq, and local Ollama models, LibreChat serves as a universal AI workstation.

How to Install LibreChat

Deploying LibreChat is straightforward using Docker Compose (`docker compose up -d`). It includes built-in MongoDB storage for preserving conversation histories, search indexing via Meilisearch, and secure user authentication.

LibreChat Features

Key features include conversational branching (forking chats from any previous message), multi-agent support with the Model Context Protocol (MCP), generative UI artifacts, multi-user role management, and file upload document Q&A.

LibreChat vs Open WebUI vs AnythingLLM
