Claude Usage Monitor for Windows

Monitor your Claude Code rate limits in real time right from your Windows system tray.

A native Windows tray app that shows your Claude usage at a glance.

Lightweight (~6 MB single EXE) and fast native .NET app with Fluent Design UI. Works with both Claude Code native for Windows and Claude Code in WSL.

Rate limits are shared across claude.ai, Claude Code, and its IDE extensions, so you always know how much of your session and weekly limits you have left.

Features

- Native & lightweight — single EXE (~6 MB), no installation, no Electron, no Python. Download and run
- Zero configuration — authenticates through your existing Claude Code login. No API key, no manual token entry
- Speedometer gauges — beautiful gauges with gradient arcs (green/orange/red), animated needle, tick marks, and percentage display
- Time marker — white line on each gauge showing elapsed time in the current period, so you can instantly see whether your usage is ahead of or behind the limit
- Live tray icon with dynamic SVG icons showing usage percentage (0-100%), color-coded status dot, and theme-aware colors for light and dark taskbars
- Detail popup (left-click) — Session gauge (5h window), Weekly gauge (7d window), plus collapsible Sonnet Only and Overage cards with gradient progress bars
- Smart credential discovery — automatically finds credentials from Claude Code native for Windows or WSL distros (Debian, Ubuntu, etc.), picking the most recently used installation when both exist
- WSL availability guard — WSL paths are skipped with a 3-second timeout if WSL isn't running, so native-only users experience zero startup delay
- Fluent Design UI — Windows 11 Mica backdrop, rounded corners, smooth slide-up animation, collapsible sections, auto-sizing…
