Gauge — Claude Usage Meter

See your Claude plan limits at a glance. Session and weekly usage on your toolbar, with history and burn-rate projection.

Gauge puts your Claude plan limits directly on your Chrome toolbar. A quick glance at the badge tells you how much of your session you've used. No clicks, no navigation, no interruption to your work. ZERO SETUP If you're signed in to claude.ai, it just works. No API key, no session token to copy, no configuration. Install it and your usage appears. WHAT YOU GET • Toolbar badge showing live usage percentage, colour-coded green to red • Current session, weekly all-models, and weekly per-model limits • Countdown to each reset ("Resets in 2h 28m") • Burn-rate projection: "~2h 10m to cap" at your current pace • A trend line of your session usage over the last six hours • Optional notifications when you cross thresholds you choose PRIVACY FIRST Your data never leaves your browser. There is no server, no analytics, and no tracking of any kind. The extension cannot read your cookies, because it has no cookies permission, and it never sees your conversations, prompts, or files. It reads usage percentages and nothing else, storing them locally on your machine. BUILT TO STAY OUT OF THE WAY Checking your usage should take zero seconds and zero clicks. The badge does the work; the popup is there when you want detail. --- Gauge — Claude Usage Meter is an independent extension, not affiliated with or endorsed by Anthropic.
