LobeChat
LobeChat is the most extensible open-source chat UI available. Where Open WebUI focuses on team deployment and simplicity, LobeChat goes deep on customization - a plugin system, multi-provider routing, and built-in tools for images, voice, and code.
What it is
LobeChat is a web-based chat application built with Next.js by the LobeHub team. It supports every major LLM provider (OpenAI, Anthropic, Google, Ollama, Groq, together.ai, and more) and lets you route different tasks to different models within the same conversation.
The plugin marketplace contains 100+ plugins for web search, image generation, PDF analysis, code execution, weather, and more. Each plugin is a simple API spec that the LLM can call.
Why this matters
LobeChat's extensibility makes it a power-user tool for those who want more than a basic chat interface:
- Plugin architecture: 100+ community plugins extend functionality without modifying core code
- Multi-provider routing: use Ollama for local tasks, Claude for complex reasoning, GPT-4 for coding
- Knowledge base: upload documents for RAG without leaving the app
- Voice in/out: built-in TTS and STT support through multiple providers
Performance you'll see
LobeChat itself is a lightweight web app - it needs ~1GB RAM and minimal CPU. The performance depends entirely on your LLM backend.
