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/*.jsonl files
  • 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:
