ClaudeMeter

ClaudeMeter is a lightweight macOS menu bar app that shows how much of a Claude.ai subscription plan's usage has been consumed. It tracks the five hour session limit, the seven day weekly limit and the separate Sonnet specific limit in real time, so heavy users can see where they stand before a cap interrupts their work. It is built for Claude power users on paid plans, including developers who lean on Claude Code. A color coded icon in the menu bar turns green, yellow or red as usage climbs, with six icon styles to choose from, and a flame indicator warns when the current pace is faster than the allowance can sustain. Native notifications fire at configurable warning and critical thresholds, which default to 75 and 90 percent, and usage refreshes automatically every one, five or ten minutes. Usage data can be exported as JSON for scripts, dashboards or a Claude Code status line. Setup uses a wizard that imports the existing Claude session from a signed in browser or accepts a pasted session key, and the key is encrypted in the macOS Keychain rather than leaving the machine. ClaudeMeter is free and open source under the MIT license. It installs through Homebrew or as a signed and notarized download from GitHub Releases, and it requires macOS 14 Sonoma or later. The app is an independent project by developer Edd Mann rather than an Anthropic product, and it reads usage through the user's claude.ai web session, so it depends on that session remaining valid.
