Meterous par Adam Mackey

Meterous is a usage meter for Claude subscribers. It lives in your browser's toolbar and shows three meters at a glance:

• Current session — how much of your 5-hour window you've used, and when it resets
• Fable — your weekly Fable allowance, if your plan has one
• Weekly — your usage across all models for the week

The toolbar badge shows your session percentage and the ring around the icon fills with your weekly usage, so you can see where you stand from any tab without opening anything. Click it for all three meters, each with a progress bar, the percentage used and the exact reset time. Colors follow claude.ai's own warning levels, so amber and red mean the same thing they do on the Usage page.

WHY METEROUS
• One click instead of digging through Settings → Usage
• Visible from every tab, not only while you're on claude.ai
• Refreshes every five minutes, and right after a limit resets
• Light and dark mode, keyboard and screen-reader accessible

PRIVATE BY DESIGN
Meterous reads the same usage numbers shown on claude.ai's Usage page, using the login already in your browser. It never asks for your password, never touches your login cookies, and never reads your conversations. It doesn't change the claude.ai page, it can't access any other website, and it has no servers and no analytics: nothing leaves your computer.

FREE
Meterous is free and made by one person, with nothing locked. If it helps you out, there's a "buy me a coffee" link in the popup.

REQUIREMENTS
A Claude subscription, signed in to claude.ai in this browser. Limits vary by plan; meters your plan doesn't report are greyed out.
