NanoClaw (qwibitai/nanoclaw) is a security-focused lightweight alternative to OpenClaw with approximately 21,500 GitHub stars. Written in TypeScript, it consists of only ~700 lines of code.
All agents run in isolated Linux containers — Apple Container on macOS or Docker on other platforms — ensuring that bash access runs inside the container and not on the host system. The binary footprint is approximately 800 KB with a minimum of 64 MB RAM for container isolation.
NanoClaw connects to WhatsApp, Telegram, Slack, Discord, and Gmail. It is built on the Anthropic Agents SDK. Supports Linux, macOS (Apple Container), and Windows (Docker).
