Clockwork
The calendar where your AI agents show up for work
A macOS calendar for coding agents. Book Claude Code, Codex CLI, OpenCode or Hermes like a meeting, with a dollar cap, a turn cap and a wall-clock timeout. The run executes in a fresh git worktree under a macOS Seatbelt sandbox (or ephemeral Docker), never touching your checkout or main branch. Risky actions pause for approval; about two minutes of silence is a no. Every run files a searchable report with diffstat, cost and transcript.
What is Clockwork?
Clockwork is a macOS calendar for coding agents. You book Claude Code, Codex CLI, OpenCode or Hermes like a meeting, with a dollar cap, and the job runs unattended in a sandboxed git worktree, then files a readable report. It is for people who already have a CLI coding agent and want scheduled, isolated, reviewable runs instead of retyping repo chores.
Key features
- Engines: Claude Code, Codex CLI, OpenCode and Hermes Agent on the logins you already have, switchable per task
- Optional own keys for OpenAI-compatible providers (Anthropic, OpenAI, Google, OpenRouter, xAI, Mistral, DeepSeek, Ollama, custom gateways), stored in the macOS Keychain
- Each run gets a fresh git worktree and branch; writes outside that worktree are denied; SSH keys, cloud credentials, GnuPG and shell history are unreadable
- Supervisor-enforced dollar cap, turn cap and wall-clock timeout, outside the model
- Risky actions pause for approval; about two minutes of silence is treated as no
- Thirteen shipped specialist profiles (Dep Surgeon, Test Doctor, Bug Hunter, Code Reviewer, Security Auditor, Docs Scribe, and others) plus custom profiles and agent chains
- Calendar recurrence via RRULE or cron in the schedule's IANA time zone, plus HMAC-verified webhooks and GitHub event triggers (two event triggers on the free tier)
- Every run files a searchable report: summary, branch and diffstat, cost vs caps, approvals, full transcript with credentials masked best-effort; data lives in SQLite in your home directory on loopback only
Who it's for
- Scheduling recurring dependency bumps, flaky-test triage, docs drift, or repo-health digests so the agent works a night shift you can review in the morning
- Running an unattended coding-agent job without giving it your ~/.ssh, cloud credentials or main branch
- Chaining scan → fix → test → PR so each stage receives the previous report
- Keeping a personal calendar (ICS) next to scheduled agent work
When not to use it
Mac-only, Apple silicon, macOS 14+, Node 22, and at least one engine CLI on PATH. The build is unsigned and not notarised, so Gatekeeper quarantine must be cleared after verifying the checksum. Jobs run only while the Mac is awake. The app is source-available and proprietary except for the Apache-2.0 sandbox profile; do not treat the whole product as open source. Commercial use needs a written licence. Pro and Teams tiers are built but not priced.
FAQ
How much does Clockwork cost?
Nothing for personal, non-commercial use: no account, no card, no telemetry. Provider usage is billed by the provider, never marked up. Commercial use of any tier needs a written licence from the author. Pro and Teams exist in the product (longer history, policy engine, more event triggers) but are not for sale yet.
Can an agent touch my main branch or my keys?
No. Each run works in its own worktree on its own branch. A global deny-list that no profile can override blocks force-pushes to protected branches and package publishing. Files under .ssh, .aws, .gnupg and shell history are unreadable to the agent.
Does it run while my Mac is asleep?
No. Runs execute only while the Mac is awake. A closed lid on battery defeats the power assertion. Missed runs follow the policy you chose: run late, skip, or ask. Overnight work needs an always-on Mac.
Is it open source?
The sandbox profile, credential deny-list and run-environment allowlist are published under Apache-2.0 with tests, in packages/runner. The rest of the app is proprietary, source-available software. Reproducible builds are not yet supported; releases come from CI with published checksums.
