Every coding agent rents a box in someone’s cloud, then forgets it. heyvm gives yours a stateful computer on your own hardware — branch-paired, forkable, one command to a URL.
> One sandbox per branch.
> Runs on your metal, not ours.
> A public URL when you want one.
Drive agents on your machine from anywhere
> Join your machines into one virtual network
> Expose any sandbox over peer-to-peer iroh
> Dial a service from anywhere — no port forwarding
> The box never leaves your hardware
One API, every backend
> KVM, libvirt, apple_virt, bubblewrap, hyper-v
> Snapshot and fork any box in seconds
> Proxy, share, and ssh into it from anywhere
> Same lifecycle on every backend
