ZeroClaw (zeroclaw-labs/zeroclaw) is a full-featured reimplementation of OpenClaw written in Rust, created by a team from Harvard, MIT, and the Sundai.Club community.
Taglined “Fast, small, and fully autonomous AI personal assistant infrastructure — ANY OS, ANY PLATFORM,” ZeroClaw achieves remarkable performance: a ~3.4 MB binary, under 5 MB RAM usage, and boots in under 10ms — approximately 400x faster than the original OpenClaw. It supports 22+ AI providers.
ZeroClaw supports Linux, macOS, and Windows, as well as ARM, x86, and RISC-V architectures. It features a `zeroclaw migrate openclaw` command to import existing OpenClaw config and memory. Security is a top priority with built-in pairing, sandboxing, and allowlisting.
Mirrors and community forks include: openagen/zeroclaw, theonlyhennygod/zeroclaw, Pendia/ZeroClaw-AI-OpenClaw-in-Rust, and bigdatasciencegroup/openclaw-rust-zeroclaw.
