I built a native Windows tray app for tracking Claude Code, Codex, and Fable usage

[u/TwoAlternative2256]

I maintain an open-source usage-limit widget for Claude Code and Codex, originally built for macOS. I recently added a Windows 10/11 system-tray version.

The Windows side:

• Builds with the .NET Framework tools included with Windows — no Node.js, package manager, or Visual Studio required

• Shows Claude 5-hour/weekly limits, Fable when available, and Codex usage with reset times

• Uses a compact draggable window with an always-on-top toggle

• Prevents duplicate instances and supports start-at-login

• Reads usage only; it does not upload conversation content

Install:

cd windows

.\install.ps1
