Ask Grok how your machine is doing.

“This thing’s bored. Throw work at it.” — Grok, after checking the 4 vCPUs and 8 GB of RAM it woke up with in the session on this page. Boot a sandbox and Grok launches itself at first boot, always-approve on, on a machine that’s disposable by design.

How you set up Grok in the cloud

01

Sign in

Email if you want it simple, a crypto key if you want anonymity. No passwords — every session is cryptographically signed.

02

Boot Grok

A fresh Firecracker microVM boots and Grok installs and launches itself at first boot. On pay-per-use a metered key is injected; or paste your own key at boot.

03

It’s live in your browser

A full-root terminal opens in the browser and the box answers at its own zbox.sh subdomain. Pause parks it for free, delete wipes it for good, SSH is optional.

Questions, answered straight

Do I need an xAI API key to run Grok?
No. On pay-per-use, a metered key is injected when the sandbox boots and tokens are billed to your prepaid balance at cost plus 3% — Grok works immediately. Prefer your own billing? Paste your xAI key at boot and pay them direct.
What does running Grok in the cloud cost?
$0.0342 per hour while the sandbox runs — about $25 a month left on 24/7 — and $0 while it’s paused. You start with free credit — no card. Grok’s default machine is 2 vCPU · 4 GB RAM · 80 GB disk, and other sizes start at $10/mo.
What happens when I pause or delete a Grok sandbox?
Two buttons, honestly: Pause shuts the machine down and parks its disk for free — restore it later and pick up where the agent left off. Delete wipes the whole VM — disk, memory, network — permanently. You only ever pay while it runs.
Is it safe to let Grok run unattended with full permissions?
In a sandbox, yes — that’s the point. The box is a hardware-isolated Firecracker microVM with its own kernel and none of your files, keys, or cookies. Close the tab and it keeps working; the blast radius is one disposable machine.
Can I SSH into the sandbox?
Optionally. The browser terminal is the default and needs no setup. Add an SSH public key when you boot and you can also connect from your own terminal — same machine, same session.
