What is Nanobot AI agent?

Nanobot is an ultra-lightweight personal AI agent built in 4,000 lines of Python by HKU researchers, serving as a minimal alternative to OpenClaw.

How does Nanobot compare to OpenClaw?

Nanobot is 98% smaller than OpenClaw (4K vs 430K+ lines), supports 12+ LLM providers and 10+ chat channels, but has fewer plugins and integrations.

What platforms does Nanobot support?

Nanobot supports Telegram, Discord, WhatsApp, Slack, Feishu/Lark, WeChat, QQ, Email, Matrix, and DingTalk.

Nanobot was created by the HKUDS (Hong Kong University Data Science Lab) research group.

How many GitHub stars does Nanobot have?

Nanobot: Ultra-Lightweight 4000-Line Python Agent Hits 30K GitHub Stars

HKU researchers ship OpenClaw alternative in 4,000 lines of Python. Readable, auditable, supports 12+ LLM providers and 10+ chat channels. Hit 8K stars in 4 days at launch, now at 30K+. HN frontpage with 257 points.

Product Idea from this Signal

A CLI tool that translates skills, memory files, and channel configs between OpenClaw, ZeroClaw, and Nanobot so you can run the same agent on any runtime

70.6k ▲

Three agent runtimes now have 30K+ GitHub stars each (OpenClaw 355K, ZeroClaw 31K, Nanobot 30K). Developers invest weeks configuring skills, memory, and channels for one runtime, then get locked in when that runtime ships a breaking update or a CVSS 8.8 CVE. Each runtime uses different config formats (OpenClaw YAML + SOUL.md, ZeroClaw TOML + IDENTITY.md, Nanobot Python configs). This tool reads your agent setup from any of the three, translates it to the other two, and validates the output against the target runtime schema.
