AstrBot is an open-source all-in-one agent chatbot platform built for deploying conversational AI inside popular messaging and collaboration applications. It supports LLM conversations, multimodal interactions, agents, MCP tools, reusable skills, knowledge bases, personas, context compression, and integrations with external agent platforms such as Dify, Coze, and Alibaba Cloud Bailian.

A major focus of AstrBot is connectivity. It can connect bots to platforms including Telegram, Slack, Feishu, DingTalk, WeCom, QQ, WeChat-related channels, and others, while a large community plugin ecosystem adds additional capabilities. The platform also provides an agent sandbox for isolated code and shell execution, a web ChatUI, web search, internationalization, and several deployment methods ranging from local installations to Docker and server-control panels.

AstrBot is suitable for personal assistants, role-playing bots, customer-service systems, automation agents, and enterprise knowledge assistants that need to live inside existing communication workflows. Its combination of messaging adapters, plugins, agent tooling, and self-hosting options makes it a flexible foundation for building production-oriented conversational applications.
