What Is LobeHub?

LobeHub, commonly known as Lobe Chat, is an open-source AI chat framework that provides a polished, feature-rich interface for interacting with large language models. Unlike proprietary chat services that lock you into a single provider, LobeHub is model-agnostic — it connects to OpenAI, Anthropic Claude, Google Gemini, Ollama (for local models), and dozens of other providers through a unified interface. This means you can switch between models mid-conversation, compare outputs, and avoid vendor lock-in while keeping full control of your data.

The framework stands out for its exceptional user interface design. Every interaction feels smooth and intentional, from the conversation threading and markdown rendering to the file upload handling and code syntax highlighting. But LobeHub is more than a pretty chat window — it includes a robust plugin ecosystem that extends its capabilities with web search, image generation, code execution, knowledge base retrieval, and custom tool integrations. The plugin marketplace offers community-built extensions, and developers can create their own using the well-documented plugin SDK.

LobeHub is designed for both individual users and teams. You can run it locally for personal use, self-host it on your own server for a team, or deploy it to cloud platforms like Vercel for public-facing applications. It supports knowledge base features with RAG (Retrieval-Augmented Generation), text-to-speech and speech-to-text for voice interactions, multi-modal inputs including images and documents, and conversation management with folders, tags, and search. Whether you're building a personal AI assistant, a team knowledge hub, or a customer-facing chatbot, LobeHub provides the foundation.
