ZeroClaw dropped Feb 13, 2026: 3.4MB Rust binary, <5MB RAM, 22+ LLM providers, modular hot-swappable subsystems. Built by Harvard/MIT students. 'Zero overhead, Zero compromise.' 27+ contributors.

Product Idea from this Signal

A minimal Rust runtime that shrinks the OpenClaw agent footprint to run on edge devices and IoT hardware

1.6k ▲

Standard OpenClaw requires Node.js, hundreds of megabytes of dependencies, and gigabytes of RAM, making it impossible to run on edge devices, Raspberry Pis, or constrained cloud instances. ZeroClaw proved the concept with a 3.4MB Rust binary booting in 10ms using under 5MB RAM, earning 2500+ engagements and 500 GitHub stars. But ZeroClaw is a standalone rewrite, not a compatible tool. This product builds a lightweight OpenClaw-compatible agent runtime that strips unnecessary features, compiles to a small binary, and runs the same skills and MCP tools on hardware with as little as 256MB RAM.
