ClaudeUsageBar

ClaudeUsageBar is a lightweight, open-source macOS menu bar application that tracks your Claude AI usage in real-time. It provides a simple way to monitor both session and weekly usage limits, helping users plan their work around available capacity and avoid unexpected interruptions when hitting usage thresholds.

• Menu Bar Native - Lives quietly in your macOS menu bar with one-click access to view current usage. Supports Cmd+U keyboard shortcut to open from anywhere on your system.

• Smart Notifications - Receive alerts when approaching usage limits at 25%, 50%, 75%, and 90% thresholds, ensuring you're never caught off guard.

• Reset Countdown - Displays exactly when your usage resets, allowing you to plan your Claude interactions around your available capacity.

• Privacy First - No data collection, analytics, or telemetry. Your session cookie and usage data stay entirely on your local machine.

• Open Source - Fully open source and free forever. Users can inspect the code, contribute improvements, or fork the project for their own needs.

• Lightweight Performance - Under 5MB in size with minimal CPU and memory footprint. Built native for both Apple Silicon and Intel Macs.

To get started, download the installer from GitHub, grant necessary permissions, and set up your session cookie from claude.ai. The app fetches usage data directly from Anthropic's API using your session cookie stored locally. Works with both Claude Free and Pro plans, with Pro users seeing additional weekly Sonnet usage information. Requires macOS 12 or later.
