Zipbox

Zipbox gives AI coding agents their own disposable cloud computer — a real Linux microVM with full root, live in seconds. Each sandbox comes with a durable identity: a real inbox at [email protected], a public HTTPS domain at name.zbox.sh, and EVM + Solana wallets. Pick an agent (Claude Code, Codex, Cursor CLI, Grok, Pi, and more) and a pre-warmed machine is handed to you already running — no install, no Docker, no cold start. Built for safe unattended agent work: hardware-isolated Firecracker microVMs (own kernel, not shared containers), public-key session auth (no passwords), pay-per-use billing only while the box runs, free pause with disk preserved. Free credit to start, no card required. Ideal for running agents in YOLO/auto-approve mode, parallel experiments, untrusted repos, overnight refactors, and anything you'd never hand your laptop root for.
