AstrBot is an open-source platform for building and deploying AI chatbot assistants that connect to popular messaging apps. It acts as a bridge between multiple AI language models and various instant messaging platforms, so you can deploy a chatbot on Telegram, Discord, WeChat, Feishu, DingTalk, Slack, or other services using the same configuration and plugin system. The platform handles the infrastructure work of managing conversations, routing messages, maintaining context, and interfacing with LLM providers so you can focus on customizing the bot's behavior. It supports connecting to many AI providers including OpenAI models, Google Gemini, and others, as well as integration with agent platforms like Dify and Coze. Features include multi-turn conversation history, knowledge bases for retrieval-augmented generation (which lets the bot answer questions using your own documents), custom personas, MCP tool-calling support, and an agent sandbox for safe code execution. The plugin marketplace contains over 1000 community-built extensions available for one-click installation, covering use cases like image generation, translation, weather lookup, and more. The project includes a web UI for configuration and management, and a chat UI for direct interaction. You would use AstrBot when you want to add an AI assistant to a team chat platform, build a customer-facing chatbot, create a personal AI companion across multiple messaging apps, or run automation workflows triggered by chat messages. The tech stack is Python, requiring version 3.12 or later. Deployment options include a uv package manager installation, Docker and Docker Compose, and a desktop application. The project is free and open source.
