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.

Inside the app

Small, quiet, and always right there.

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.

The Thresholds tab: for each limit a list of percentages, 80 and 95 for the Session, 70 and 90 for the Week, with a field to add one, and a switch for the notification when a limit is renewed
The Look tab: the layer, On desktop or Above all, row or column, a switch for the captions under the gauges, and sliders for size and opacity

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.

Neon Labs is not affiliated with Anthropic, and Neon Gauge is not an official Anthropic product. Claude is a product of Anthropic.

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.
