In short

AstrBot is a self-hosted, model-agnostic AI assistant that bridges messaging platforms like Telegram, Discord, and QQ with various LLM providers. It is best for users seeking a free, open-source solution with a large plugin ecosystem and multi-platform support.

Best for

Pick AstrBot if you want a self-hosted, model-agnostic chatbot that lives inside Telegram, Discord, QQ, Feishu, or all of them at once.

Skip if

Skip it if you want a hosted SaaS assistant or a US-style enterprise vendor with SOC 2 paperwork rather than a community-run open-source project.

AstrBot is an AGPL-3.0 licensed agentic AI assistant framework built for individuals and group chats. It exposes a single bot persona across more than a dozen messaging platforms (QQ, WeChat Work, Feishu/Lark, DingTalk, Telegram, Discord, Slack, LINE, KOOK, Matrix, Mattermost, and others) while routing conversations through whichever LLM provider you wire up. Out of the box it handles multimodal chat, MCP tools, a knowledge base, persona customization, and a sandboxed code-execution agent, all administered through a visual web panel.

Where AstrBot stands out is the breadth of the integration matrix: it natively talks to OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Ollama for self-hosted models, plus Dify, Coze, and Alibaba Bailian for hosted agent backends, and ships speech-to-text and TTS hooks. A marketplace of more than 1,000 community plugins installs with one click, which makes it the de facto choice if you want a self-hosted Chinese-ecosystem-aware chatbot rather than something locked to a single vendor's app. It's free to self-host; there is no SaaS tier or paywall, your only real cost is the LLM API bill.

The project originates from the Chinese open-source community (AstrBotDevs on GitHub), so documentation and plugin metadata sometimes lean Chinese-first, and the heaviest platform support is for QQ/WeChat/Feishu. Western operators running Telegram or Discord bots will be fine but should expect to lean on machine translation for some plugin readmes.

Editor's take

AstrBot is the most ambitious open-source messaging-bot framework we've seen on the Chinese side of the ecosystem, and the integration matrix punches well above competitors like Botpress for plain LLM-as-chatbot use cases. The Chinese-first docs are the real friction; if you can tolerate that, it's the cheapest path to a multi-platform, multi-LLM agent.
