Claude Usage Monitor is a native macOS menu bar application designed to provide real-time tracking of your Claude.ai usage without the need for an API key. This streamlined tool integrates seamlessly into the macOS menu bar, offering a hassle-free user experience.

Key Features

• Menu-bar only: Operates without a Dock icon, minimizing distractions while providing essential usage insights.
• Live usage counter: Displays real-time metrics in the format used/limit (e.g., 45/100) right within the menu bar.
• Colour-coded status: The tree icon provides visual feedback on usage — transitioning from green to yellow, and finally red as limits approach.
• Popover Dashboard: Access a detailed overview featuring a circular progress ring, reset countdown, and additional statistics through a simple popover interface.
• Session-aware tracking: Employs a fetch interceptor to capture Claude's internal rate limits, ensuring that usage data reflects real-time session activity rather than just the overall billing period content.
• Auto-refresh: Automatically updates every 5 minutes, with manual refresh options available in the popover.
• Persistent login: Utilizes WebKit to keep your Claude session active automatically, requiring login only once.

Technical Details

• Data Source: The app utilizes a hidden WKWebView to load usage information from claude.ai/settings/usage, leveraging the stored browser session to capture real-time data through an injected JavaScript fetch/XHR interceptor.
• Session Management: Automatically persists cookies, ensuring continuity between app launches. If the session expires, users will be prompted to log in again.

Compatibility

• Requires macOS 13 Ventura or later and an active Claude.ai account (available in Free, Pro, Team, or Max tiers).
• An internet connection is necessary for functionality.
