OpenClaw (Rust) hits 3.4k stars in 2 days!

Discover ZeroClaw, a Rust powered AI agent runtime that redefines infrastructure with minimal resource usage.

This is simply the “Cambrian Explosion” in the OpenClaw universe!

Just yesterday, I shared the Rust version of OpenClaw: Moltis (focused on secure sandboxing), and now I’ve come across another Rust implementation on GitHub—this one is even more hardcore, called ZeroClaw.

It was open-sourced just 2 days ago and has already amassed 4.9K stars on GitHub! (Note: the original post mentioned 3.4K, but the number has grown rapidly since then.)

While Moltis leans more toward an AI CLI/local development assistant, ZeroClaw is geared toward being the core infrastructure for Agent systems.

It’s not just a simple rewrite in Rust—it redefines AI Agent infrastructure from the architecture level. It turns an Agent into a mere 3.4MB system-level daemon process with startup times under 10ms.

Its positioning is crystal clear: minimal by default, secure by default, replaceable by default—it should feel as lean, secure, and pluggable as an operating system.

At its core, it’s not really an “AI application”—it’s an Agent runtime + plugin-style framework kernel.
