Agent Computers

A sandbox is disposable on purpose. The second your agent does something worth keeping, the box that did it is gone. An Agent Computer is the opposite: a real, stateful machine you can mount into, snapshot, and fork — running on your hardware, never ours.

THE PROBLEM

Agents don’t need a scratchpad

An ephemeral sandbox has no memory and no address. Perfect for a throwaway script. Useless the moment you want to keep the environment, hand it to a teammate, or reproduce yesterday’s bug. So the work that matters keeps getting thrown away with the box that made it.

Give the agent somewhere to live instead: a filesystem that persists, dependencies that stay installed, an identity on the network. Close the lid, come back tomorrow, pick up exactly where it left off.

HOW IT WORKS

Four moves, one machine

01

Mount

Bind a local directory in and sync as you type. Your editor stays on your laptop; execution moves into isolation.

02

Install

Node, Python, Rust, system packages, your private CLIs. Shape it once. It’s still there next session.

03

Connect

Attach Claude Code, Cursor, OpenCode, any ACP agent — or open the machine straight in Zed or VS Code over SSH.

04

Snapshot & Fork

Freeze a known-good state. Fork it into a hundred copies for experiments, reviews, or a fleet of agents. 

# Create a computer and mount your code into it
heyvm create my-project --mount ./src:/workspace

# Connect your agent of choice
heyvm connect my-project --agent claude-code

# Open it directly in your editor over SSH
heyvm ide my-project

# Fork a known-good machine into a fresh copy
heyvm fork my-project --name experiment-a
THE DIFFERENCE

Rented box vs. your computer

E2B, Daytona, CodeSandbox sell isolation to SaaS teams: an ephemeral box, tied to one app, wired through an SDK. Excellent at what it’s for. Wrong shape for the durable, personalized machine your internal software actually needs.

A rented sandbox

  • Forgets everything when the run ends
  • Lives in the vendor’s multi-tenant cloud
  • Tied to one app, configured through an SDK
  • Isolation is the whole product

A heyo Agent Computer

  • Snapshot it, resume it, hand it off
  • Runs on your Mac, your metal, your VPC
  • A portable artifact you fork like a branch
  • Isolation, plus a network and a data plane

Give your agent somewhere to live

Stateful, isolated, portable — on hardware you own.
