Build AI agents for the messaging platforms your users already use.

---

LangBot is an open-source platform for building and running AI agents across Discord, Telegram, Slack, LINE, WeChat, QQ, Lark, DingTalk and more. Connect your preferred models, knowledge bases, and tools to create support assistants, automate team workflows, or help manage your community — all from one web dashboard.

Highlights

• Agents that do more than chat — Multi-turn conversations, tool calling, multimodal input, and a code sandbox for working with files and running tasks.
• Your models and workflows — Use OpenAI, Anthropic, Gemini, DeepSeek, or local models with Ollama. Connect existing applications built with Dify, Coze, n8n, and Langflow.
• Knowledge-backed answers — Bring your documents into conversations with built-in RAG and external knowledge-base integrations.
• An extensible toolkit — Add plugins, MCP servers, and skills from the extension marketplace, or build your own.
• One place to manage your bots — Configure bots and pipelines, collaborate with teammates, manage access, and monitor conversations and model usage through the web dashboard.

Get Started

LangBot Cloud (Recommended)

Build and manage your bots online without deploying or maintaining a server.

Self-host with Docker Compose

With Git, Docker, and Docker Compose installed, run:

git clone https://github.com/langbot-app/LangBot
