LibreChat
LibreChat
An open-source, self-hostable AI chat platform that unifies every major model provider, agents, MCP tools, and code execution in one interface.
Key features
- Universal Model Switching: Select between Anthropic, OpenAI, Azure OpenAI, Google, Vertex AI, AWS Bedrock, Mistral, DeepSeek, Groq, Cohere, OpenRouter, Perplexity and any OpenAI-compatible custom endpoint from one chat, including local providers like Ollama and Apple MLX, without a proxy.
- No-Code Agents and Marketplace: Build specialized assistants with file handling, tools, and API actions, share them with specific users or groups, and discover community-built agents in an in-app marketplace.
- Skills and Subagents: Package reusable SKILL.md instruction bundles for manual, automatic, or always-on workflows, and delegate focused work to isolated child agent runs with their own context windows.
- Sandboxed Code Interpreter: Execute Python, Node.js, Go, C/C++, Java, PHP, Rust, and Fortran in a fully isolated environment with direct file upload, processing, and download and no data leaving the sandbox.
- Model Context Protocol Support: Connect agents to any MCP server for external tools and services, with OAuth-backed MCP sessions for controlled access.
- Generative UI Artifacts: Render React components, HTML, and Mermaid diagrams inline in chat, open them fullscreen, and export diagrams as SVG or PNG.
