Working
A blue ring fills as Claude works through its steps. Next to it: the step it is on, the count so far and the time elapsed.
For Claude Code on Mac
Know the moment your AI is done.
Kettlebar is a small glass pill at the top of your Mac that shows what Claude Code is working on. When it finishes, you hear a chime and the edges of your screen glow green.
- macOS 14 or later
- One-time purchase
- Nothing leaves your Mac
Why it exists
Claude finished eleven minutes ago. You were still scrolling.
You hand Claude a task and switch to something else. Then you guess. You check back too early, or far too late, or it has been sitting on a permission prompt the whole time.
Kettlebar ends the guessing. One glance tells you where things stand, and you hear it the moment the work is done.
That is all it does. It is an indicator, not a control panel.
How it works
Three states. One glance.
The pill shows the project, the current step, how many steps are done and how long it has been running.
Needs you
When Claude stops and waits for you, the pill turns amber and plays a ping. Nothing sits blocked while you are elsewhere.
Done
A chime plays and a green glow runs around the edges of your screen for two seconds. Then it is gone.
Several agents
Four agents running. Still one pill.
The pill follows one agent. Every other agent is a small coloured bar underneath, so you can see who is working, who is waiting and who has finished without reading a word.

01
Bars
One bar for each agent that is not in the pill. Blue is working, amber needs you, green is done.

02
Chips
Click the bars and they open into chips, each with its state and project name. After four seconds they fold back into bars.

03
Swap
Click a chip and that agent moves into the pill. Try it in the preview at the top of this page.
The details
There when you look. Out of the way when you don't.
On top of everything. In the way of nothing.
Kettlebar stays visible over every app and every full-screen Space, and it never takes focus from what you are typing. Clicks pass straight through the space around it.
Liquid Glass
On macOS 26 the pill is clear Liquid Glass that hangs from the top edge of the screen. Earlier versions get a frosted pill.
Two sounds and a glow
A chime for done, a ping for needs you, so you can tell which it is without looking. Each one, and the glow, can be switched off.
Any Mac, notch or not
Kettlebar runs on any Mac with macOS 14 or later. It does not depend on a notch, so it sits the same way on every screen.
Settings in the menu bar
Connect or disconnect Claude Code in one click. Turn the chime, ping and glow on or off, adjust the Darken slider, and choose whether it opens at login.
Nothing leaves your Mac
No account and no tracking. Kettlebar only receives short status updates from Claude Code. It never sees your code or your prompts.
A native Mac app
Written in Swift for macOS. It works with Claude Code in the terminal and in the Claude desktop app.
