A Windows utility · Not for download
Neon Gauge
How much of your Claude limit is left, in rings on the desktop.
Neon Gauge is a small, transparent block of rings that sits on the Windows desktop. There is one ring for every limit of a Claude subscription: the 5-hour Session, the Week, and the weekly limit of a model that has one of its own, named as Claude names it. Each ring fills as the limit is spent, with the percentage in the middle and the time until it resets underneath.
Around every ring runs a thinner one that fills with the time of the window. If the thick ring is ahead of the thin one, you are spending faster than the clock runs; if it lags behind, you have room to spare. A ring turns gold and then red as it crosses the thresholds you set for it, and Windows tells you once when it does.
It is a tool we made for our own desk, and it stays there: it is not for download. This page shows what it does.

Reading it
One look: how much, and how soon.
- The SessionThe rolling 5-hour window that opens with your first message. The ring is how much of it is spent; underneath, how long until it resets.
- The WeekThe 7-day limit across all models. Its reset is a weekday and a time, because it does not move.
- A model’s own limitWhere Claude gives a model a weekly limit of its own, it gets a ring, named after the model. One appears the first time it is reported.
- Gold, then redA ring takes the colour of the highest threshold it has crossed. Here the Week has passed its first one.
Inside the app
Small, quiet, and always right there.
A ring for every limit
The Session (5 h), the Week and a model’s own weekly limit, which appears by name the first time Claude reports one. Switch each ring on or off on its own.
Usage against time
A thick ring for what is spent and a thin one around it for how much of the window has passed. Usage running ahead of time is the whole message.
The countdown to the reset
Under each ring: “in 2 h 20 min” for the Session, a weekday and time for the weekly limits. It counts down on the PC, every second, between readings.
Colours from thresholds
Every limit has its own thresholds, up to three. From the lowest the ring turns gold, from the highest red, and a Windows notification says so — once per threshold, per window.
Above all, or on the desktop
Keep it over every window, or under them, on the desktop itself. A shortcut — Win+Alt+G unless you change it — peeks at it: hold to look, tap to keep it up.
Honest when it does not know
When the sign-in it reads has expired, the rings go grey and say when they were last read, and stay quiet. They never show a number as if it were fresh.
Small, and out of the way
No window to look after: a tray icon, a settings window with five tabs, a block you drag into place. It asks for a fraction of a percent of one processor core.
English and Polish
It speaks the language of the PC, and the settings can change that.
Settings
Every change acts at once.
An ordinary window with five tabs — the gauges, their thresholds, the look, the general settings and an About page. There is no OK button to forget: move a slider and the rings change behind it.


Where the numbers come from
It borrows a sign-in. It never changes it.
Neon Gauge asks Anthropic for the usage of a Claude subscription, and to do that it reads the sign-in that Claude Code already keeps on the same PC. It only reads: it never refreshes the sign-in, never writes to it and never signs in on its own. The sign-in goes to Anthropic’s API and nowhere else.
When that sign-in expires, because Claude Code has not been used for a while, the rings go grey and show when they were last read, until a fresh one appears. Nothing is sent to us, and there is no account and no tracking.

From the studio
Built by Neon Labs.
Neon Gauge is made by Neon Labs, a tiny independent studio making simple, ad-free games — and, now and then, a tool for the desk it was made at. This is one of those: it started on ours, with a wish to see the limit coming before it arrived. It is not for download, so this page is all there is.
