UsageBar – Claude Code and Codex rate limits in the macOS menu bar (github.com)

A new macOS tool called UsageBar has been introduced to help users monitor their usage limits for Claude Code and Codex directly from their menu bar. This app provides color-coded visual signals indicating usage levels (green, yellow, red) and includes live tracking for both 5-hour and weekly usage limits. With zero setup required for those using the Claude desktop app, it sends native notifications when usage thresholds of 80% and 95% are reached, and it displays a 24-hour sparkline of Claude activity. Users can choose from various display styles, with options for countdown timers and percentage indicators to enhance usability. This development is significant for the AI and machine learning community as it helps optimize resource usage, preventing unexpected disruptions that could affect development workflows. With its streamlined integration and zero configuration requirement, UsageBar empowers developers to efficiently monitor their access to Claude and Codex APIs in real-time. The application is built as a single native Swift executable, ensuring performance and reducing dependencies, making it easier for users to install either via Homebrew or by directly downloading the application. The app also supports additional customization for advanced users, including command line hooks for terminal status updates.
