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 2.0.70
- Hardware: a new page for your Mac's CPU, GPU, memory, disk and network. Each part shows its use over the last hour, day or week, and who used it: sessions, apps, and macOS and other users. Disk shows the disk's space first, then its activity. Hardware replaces Disk in the sidebar and "This Mac" on Sessions. Memory and disk alerts open Hardware at the part they are about.
- Usage: when Anthropic refuses an account's usage reading while the account still works, the account says "Usage refused" instead of "Usage unavailable". Kairos then renews that account's login itself with a one-word request, at most once every six hours, so the reading can work again. It sends none while 5-hour windows are off in Settings.
- Sign-in: a sign-in made as a different account than the one asked for no longer passes quietly. Kairos tells you which account you signed in as, and switches back to the account you had chosen. The log also says where each sign-in page opened.
- Billing: Google and Apple don't allow their sign-in inside an app's window. Where the Billing window said only "There was an error logging you in", it now says to choose Continue with email: Claude sends a code to the same address.
- Renewals: an account's renewal day now comes from its billing page ("will auto renew on Dec 6") once you open Billing for it in Kairos, instead of a month on from when Claude Code first saw the subscription. Rotation plans each account's week to that day. The Billing window now reads pages in any currency, not only dollars.
- Accounts: the Resets column, at its narrowest, puts a time on two lines instead of cutting it.
- Dashboard: the web dashboard has a Hardware section too, with the same parts, ranges and who used them, and a table for each chart.
- Docs: Kairos's documentation is now on the website, under Docs.
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. The docs explain every screen, setting and chart.
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
