Basic Information

Lobe Chat is an open-source chat UI and extensible framework for building, deploying, and running private conversational applications powered by large language models. It provides a modern, design-focused interface and runtime that supports multimodal interactions (text, images, audio), function-calling plugins (MCP), and an agent marketplace. The project targets both end users who want a private ChatGPT-like app and developers who need a platform to connect multiple model providers, integrate external tools and data, and publish custom agents and plugins. Lobe Chat supports one-click deployment options, self-hosting via Docker or cloud platforms, local model execution (Ollama), multi-user management, and both local and server-side databases, enabling private, production-ready chat services with customizable themes, PWA/desktop clients, and internationalization workflows.
