claudechecker/windows

ClaudeChecker for Windows

A native Windows port of ClaudeChecker — a system tray app for monitoring your Claude AI usage limits in real time.

Requirements

• Windows 10 / 11 (x64)
• .NET 8 Runtime
• WebView2 Runtime (usually pre-installed on Windows 11)

Building

cd windows
dotnet build -c Release

The output is a single ClaudeChecker.exe in bin\Release\net8.0-windows\.

Assets: You need to supply Assets/icon.ico and Assets/icon.png (128×128) before building. Copy them from the macOS project's ClaudeChecker/Assets.xcassets/AppIcon.appiconset/.

Features

• System tray icon — left-click to show/hide the popup
• 5-hour and 7-day usage gauges with burn rate sparklines
• Cookie-based auth via embedded WebView2 browser (sign in once, session persists)
• Auto-refresh on a configurable interval (1–10 min)
• Update checking against the same version.json / version-beta.json as the macOS app
• Beta channel toggle
• Settings panel (auth, refresh interval, update channel)

Architecture

File	Purpose
App.xaml.cs	Tray icon, popup lifecycle, refresh timer
PopupWindow.xaml/cs	Main UI — limit cards, settings, update sheet
LoginWindow.xaml/cs	WebView2 browser for claude.ai auth
UsageViewModel.cs	Data fetching, cookie handling, state
UpdateManager.cs	Version checking, download and install
Models.cs	Data models
Controls/GaugeControl.cs	Custom circular gauge
Controls/SparklineControl.cs	Burn history sparkline

Notes

• Cookies are stored in user settings (via Properties.Settings), not the WebView2 profile, so they survive WebView2 cache clears.
• Updates download a .zip, extract, and run a .bat script that replaces the exe after the app exits.
• The popup positions itself in the bottom-right corner near the system tray.
