Verdict
Moltworker doesn't run on your hardware: it runs OpenClaw in a Cloudflare Sandbox container behind a Worker. It sits next to the Pi Zero 2 W because both are ways to have an agent without a full server at home, not because one replaces the other. Until October 2026 this page called it free at low volume and bound by Workers runtime limits; its README describes a paid container.
Setup notes
Workers Paid plan, then npm install, npx wrangler secret put ANTHROPIC_API_KEY (or the AI Gateway secrets), a MOLTBOT_GATEWAY_TOKEN, and npm run deploy. Enable Cloudflare Access for the admin UI at /_admin/, pair your device there, and add R2 storage if your data should survive container restarts.
Performance
The first request can take 1-2 minutes while the container starts. The README's cost estimate assumes a standard-1 container (1/2 vCPU, 4 GiB of memory, 8 GB of disk): about $34.50 a month running around the clock.
What breaks
- Free hosting: the Workers Paid plan is required
- State across restarts without R2 storage
- Anything that needs official support: it is an experimental proof of concept
