LangBot is an open-source, production-grade, LLM-native instant messaging bot platform. It connects large language models — OpenAI, Anthropic, Gemini, DeepSeek and more — and Agent platforms like Dify, Coze and n8n to mainstream messaging platforms including Discord, Telegram, Slack, QQ, WeChat, WeCom, Lark and DingTalk. With built-in Agent, RAG knowledge base, MCP, Skills and a code sandbox, plus an out-of-the-box web management panel, you can get your AI bot online in minutes — no hand-written config files required.

  • Community operations: provide AI-powered Q&A, content moderation and interaction in Discord, Telegram and QQ groups.
  • Workflow integration: plug your existing Dify / n8n / Coze workflows straight into chat platforms — no need to rewrite business logic.
