Windows System Tray Monitor for Claude Code Quota
A developer has built a Windows system tray application to monitor Claude Code usage quotas in real-time. The tool addresses the frustration of manually checking usage limits during coding sessions.
Core Features
The application provides several key monitoring capabilities:
- Tray icon with color coding: Green (0-50% usage) → Orange → Red → Dark red → Grey at 100%
- Right-click context menu: Shows session percentage (5h), weekly percentage (7d), and time to reset
- Automatic refresh: Updates every 5 minutes using the official Anthropic OAuth API
- Fallback mechanism: Uses cached data if rate-limited by the API
- Desktop notifications: Alerts at 85% and 90% usage thresholds
Dashboard Components
The browser-based dashboard includes four tabs with detailed analytics:
- Today: Hourly bar chart, token comparison vs yesterday, active sessions
- This Week: Daily bar chart, peak day identification, daily average
- This Month: Same structure for current month analysis
- All Time: Quota trend chart with 80%/95% thresholds, top sessions, full statistics
Technical Details
The application has specific technical requirements and implementation details:
- Data source: Token data comes from local
~/.claude/projects/*.jsonlfiles - Privacy: Only quota percentage calls go to Anthropic API; all other data stays local
- Requirements: Windows 10/11, PowerShell 5.1 (pre-installed), Claude Code logged in
- No dependencies: No Node.js or additional installations required
Setup Process
Installation is straightforward:
- Download ZIP from GitHub: https://github.com/edi19863/claude-usage-tray
- Double-click
start.vbsto launch - Run
setup-autostart.batfor automatic launch at login
The developer accepts support via Ko-fi: https://ko-fi.com/edi1986
