For Mac · Free
Air traffic control for your coding agents.
Kairos watches every coding session on your Mac, whichever tool runs it. It knows what each account has left, when it resets, and which session is waiting for you.
Apple silicon and Intel
Or with Homebrew: brew install --cask matih-labs/tap/kairos
What it does
One list
Claude Code, Codex and other tools together, each session with its account, plan and state.
The week ahead
Each account's five-hour and weekly limits, forecast, so you know before work stops.
Pause and resume
Before an account runs out, its sessions stop where they can pick up, and carry on when limits return.
Baton
Hands a task from one tool to another, with what was done so far.
Night Shift
While you are away, the chores you wrote run on capacity that would expire. Branches only, and a brief in the morning.
On your iPhone and iPad
Kairos Code shows every session and the one waiting for you, at home or away, end-to-end encrypted. Coming to the App Store.
What's new in 2.0.69
- Rotation: a Team seat's open 5-hour window is spent before an Ultra's week. A window not used before it resets is lost, so Kairos now uses the seats while their windows are open and keeps the Ultra's week as the reserve.
- Week plan: each account says when the plan will spend it ("planned Fri 09:00", or "planned now"). The plan also says when the weeks it passes over will be spent. It no longer counts accounts that have no weekly limit.
- Pages: when a session calls a claude.ai page that belongs to another account, Kairos first moves Claude Code back to that account and asks the session to make the same call again. If it can't yet (the account is at its limit, held or needs a sign-in), the session is told why and until when, and that the page was not deleted.
- Sign-in: a sign-in for a rotation account opens in that account's own Chrome, and a check running at the same time no longer interrupts it.
- Unusual use: when Kairos asks a session about unusual use, it now reads the answer even when the session has many helpers. It then checks whether the use went down. If not, it asks once more. If the use is still up after that, it leaves it to you on Today, with both answers.
- Disk says when it is still measuring, and the next run measures only the folders that were left.
Three steps, no Terminal.
Kairos needs Claude Code on your Mac; the login it already has becomes your first account.
- 1
Download Kairos, open it, and drag Kairos onto Applications.
- 2
Open Kairos from Applications. The first time, macOS asks whether to open an app from the internet: click Open.
- 3
Click Set Up Kairos. It adds two background items and, if your Mac has none, downloads Python, so it needs the internet; then it walks you through your accounts.
That is the last download: Kairos keeps itself up to date.
Your data stays on your devices.
Kairos has no account of its own and keeps nothing of yours on a server. It reads what your tools already keep on your Mac, and talks only to the services you use, with your own sign-in. Away from home, your iPhone reaches your Mac through Kairos's relay, which passes only encrypted messages it cannot read. No analytics and no tracking, on this page too. Privacy policy
