LibreChat is an open-source, self-hosted AI chat platform with 46,000+ stars on GitHub that brings every major model provider into one enhanced ChatGPT-style interface.
If you use more than one AI provider, your work is probably scattered across subscriptions and browser tabs. LibreChat unifies them: OpenAI, Anthropic, Google, Azure OpenAI, AWS Bedrock, Groq, Mistral, OpenRouter and local models all sit behind one login, with secure multi-user authentication for teams and families. On top of familiar chat it layers the features people expect from the best commercial apps — agents with MCP support, a code interpreter, artifacts, image generation, file handling, message search, conversation branching and shareable presets — while your data stays on your own server. The interface supports speech, custom endpoints and fine-grained configuration per model, and deployment is a standard Docker setup. LibreChat is MIT-licensed, developed openly by its community, and updated at a rapid pace through 2026.
LibreChat is free and open source under the MIT license. You host it yourself and only pay the model providers whose APIs you connect — or nothing at all when using local models.
Teams, families and power users who want one private front end for many AI models — with agent features and multi-user support — instead of juggling separate subscriptions and interfaces.
