Lobe Chat

Lobe Chat is an open-source AI chat and agent platform that provides a unified interface for interacting with multiple large language models. It supports connections to local models via Ollama and major cloud providers including OpenAI, Claude, Gemini, DeepSeek, and Qwen, with the ability to switch models within a single workspace. The platform extends beyond simple chat with plugin integrations, voice input and output, image generation, and internet search.

Key features include an agent marketplace with thousands of community-contributed assistants, branching conversations that support multiple discussion threads, real-time generation of SVG, HTML, and documents, and a personal memory system that adapts to user context over time. Desktop and mobile applications are available alongside the web interface, and one-click deployment via Vercel makes self-hosting accessible.

Lobe Chat is designed for developers, researchers, and knowledge workers who want a powerful, customisable AI assistant that can run locally for privacy, integrate with a wide range of models and tools, and support complex multi-step workflows beyond single-turn chat. With 80k+ stars on GitHub, it is one of the most prominent open-source ChatGPT alternatives available today.
