Clockwork - The calendar where your AI agents show up for work
by•
Book AI coding agents on a real calendar. Clockwork runs them unattended in sandboxed git worktrees on your Mac, pauses for approval when something looks risky, and files a report with the actual dollar cost. Bring your own key or ride your existing subscription. Schedule recurring agent jobs on a real calendar, run them unattended in isolated sandboxes, and review honest reports.

Clockwork
Hello PH Folks👋 My Self Vimox Shah,
I built Clockwork because I was paying for Claude capacity that sat idle about 18 hours a day, while I re-typed the same repo chores every week by hand.
The idea is simple: if an agent can do the work, give it a workday. A slot on the calendar, a budget, permission rules, and a report when it's done.
Trusting something to run while I'm asleep meant the boring parts had to be
real:
• Runs execute inside a macOS Seatbelt sandbox, in a per-run git worktree. Writes are confined to that worktree.
• The run environment is an allowlist, so SSH_AUTH_SOCK and your provider tokens never reach the agent process.
• Risky steps pause and ask instead of failing silently or ploughing on.
• Hard budget caps in dollars, turn limits and wall-clock timeouts, enforced by the supervisor rather than the model's good intentions.
• You can check all of that rather than believe it - the sandbox, the credential
deny list and the env allowlist are Apache-2.0 in the repo, and the tests write a fake secret into `~/.ssh` and `~/.aws`, then run `cat` inside a real sandbox and assert it fails. The rest of the app is source-available under a proprietary licence, so please don't call it open source; I'd rather be precise than flattering.
Honest limits, up front:
• Runs need your Mac awake. It holds off idle sleep during booked windows when
plugged in, and tells you loudly when a miss happened instead of hiding it.
• It isn't notarised yet — an Apple certificate is $99/year and this is an
early build - so you clear the quarantine flag by hand. The install docs say exactly why.
• Apple silicon only, for now. It's free. There's no paid tier you can buy today. I'd genuinely like to hear what you'd want before trusting an agent with more of your week.
