LibreChat-AI/LibreChat
LibreChat is an open-source, self-hostable chat platform styled after ChatGPT that lets teams and individuals run a private, provider-agnostic front end for large language models. It connects to Anthropic, OpenAI, Azure OpenAI, AWS Bedrock, Google/Vertex AI, and any OpenAI-compatible custom endpoint, including local or remote providers such as Ollama, Mistral AI, Groq and OpenRouter. Its Agents feature lets users build no-code custom assistants, share them through an agent marketplace, and equip them with MCP servers, file search, code execution and reusable Skill bundles (SKILL.md); LibreChat is listed as a client implementation on the official Model Context Protocol client directory. A sandboxed code interpreter runs Python, Node.js, Go, C/C++, Java, PHP, Rust and Fortran without exposing the host system, and file uploads can be analyzed by vision-capable models. Other features include web search with pluggable providers and rerankers, generative UI code artifacts (React, HTML and Mermaid diagrams) rendered inline in chat, image generation and editing through GPT-Image-1, DALL-E, Stable Diffusion or MCP-based tools, saved and shareable presets, conversation branching and forking for context control, and a multilingual UI covering more than a dozen languages. It is built with TypeScript/React on the front end and Node.js on the back end, and deploys via Docker or one-click templates on Railway, Zeabur and Sealos. LibreChat suits organizations and developers who want a privacy-respecting, extensible alternative to hosted chat products while still being able to plug in MCP servers as agent tools.
