Your agents. Your machine. Always on.

Quartz gives you a private cloud computer that never sleeps. Hand your coding agents a task from your Mac or iPhone, and the work comes back as a pull request.

Private alpha · invite only

How it works

• One machine, yours alone. A dedicated server in the EU, created when you join and deleted when you leave.
• Bring your own AI. Sign in to Claude Code, Codex and the other agent CLIs with your own subscription or API key. Quartz never resells model access.
• Pull requests, not surprises. Agents work in sandboxes on your machine and push branches. Anything risky, like a force-push, waits for your OK.
• Mac and iPhone. Start tasks, follow them live, answer approvals from a notification, and open a terminal on the Mac.

Get it

Quartz is in a closed alpha. The Mac app and the iPhone TestFlight are shared with invited testers. Sign-in is with GitHub. If you'd like an invite, write to support@quartz.computer.
