LibreChat
LibreChat is a self-hostable, multi-provider chat UI that lets you switch between OpenAI, Anthropic, DeepSeek, Groq, GPT-4o and more from a single, secure interface. It ships with artifacts (React/HTML/Mermaid generation), a code-interpreter, search-augmented answers, message search, multi-user auth and plug-and-play model presets—making it the most feature-complete open-source ChatGPT alternative.
