Pi, the lean coding agent — live in seconds.

“I turn fuzzy ideas into working code” — Pi’s own words, from the real session on this page. One click boots a fresh microVM where Pi installs and launches itself at first boot: no install on your machine, no API key on pay-per-use, and the whole box is disposable.

you're a fresh cloud sandbox. write and run a one-liner that shows the 5 biggest things installed on this machine, then tell me what you're best at in one line
The user wants me to: 1. Write and run a one-liner ... 2. Tell them what I'm best at in one line
Let me start by running the one-liner to find the 5 biggest things installed. I'll use dpkg to list installed packages sorted by size, or use du on common directories.

The 5 biggest packages installed are:

2. vim-runtime — 36 MB
3. libperl5.36 — 29 MB
4. coreutils — 18 MB
5. perl-modules-5.36 — 18 MB
And what I'm best at in one line:
I turn fuzzy ideas into working code — writing, debugging, and shaping software faster than you can type it.

How you set up Pi 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 Pi

A fresh Firecracker microVM boots and Pi 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 API key to run Pi?
No. Pick pay-per-use and a metered key is injected when the sandbox boots — tokens are billed to your prepaid balance at cost plus 3%, and the agent works immediately. Or bring your own key at boot and pay your provider direct.
What does running Pi in the cloud cost?
$0.0137 per hour while the sandbox runs — about $10 a month left on 24/7 — and $0 while it’s paused. You start with free credit — no card. Pi’s default machine is 1 vCPU · 2 GB RAM · 20 GB disk, and other sizes start at $10/mo.
What happens when I pause or delete a Pi 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 Pi 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.
