Free macOS Menu Bar App Monitors Claude Usage in Real-Time
What It Is
A developer has created a free macOS menu bar application that monitors Claude AI usage in real-time. The entire project was built in a single Claude Code session using the Opus model, demonstrating the capabilities of AI-assisted development for creating functional desktop applications.
Key Features
- Usage Monitoring: Displays 5-hour and 7-day session usage bars directly in the macOS menu bar
- Context Window Tracking: Shows context window fill percentage with auto-compact threshold
- Notifications: Alerts users when approaching usage limits
- Global Hotkey: Keyboard shortcut to toggle the panel
- Monochrome Mode: Option for simplified display
- Native Implementation: Built with SwiftUI using Liquid Glass on macOS Tahoe
- Localization: Supports both French and English languages
- No Account Required: Only needs your existing Claude login

- SwiftUI application framework
- OAuth integration for authentication
- Context window monitoring system
- Notification implementation
- Localization setup
- Landing page creation
