Full Windows support: Native portable release with a dedicated system tray
Windows users can now enjoy a fully native, first-class experience for tracking AI quotas without jumping through complicated setup hoops. The usage tool now runs natively on Windows, fully supporting the TUI (text user interface, a screen operated purely by keyboard in the black-and-white command line without mouse buttons), the Claude Code status-line hook (a small widget that hooks itself next to your command prompt to spit out remaining quotas), and Codex history parsing. You'll find a dynamic system tray icon resting in your lower-right taskbar, displaying your Claude quota percentage; hovering over it summarizes your active windows. A left-click uses WebView2 (Microsoft's built-in engine for rendering web pages inside regular software) to launch the same 11 gorgeous HTML theme panels available on Mac, while a right-click gives you a menu to switch panels, refresh, set it to launch at login, check for updates, or quit. For those who hate setting up environments, GitHub Releases now offers a portable usage-windows.zip — just extract and double-click usage.exe. Under the hood, the CI (Continuous Integration, a robot pipeline in the cloud that automatically tests and packages the software whenever developers submit code) now uses PyInstaller (a packaging software that squashes environment-dependent Python code and its toolkits into a single executable) to build the release, smartly walling off Mac-specific dependencies. Additionally, the file-locking mechanics and command-quoting for the status-line hook have been made platform-aware so they run flawlessly on both operating systems. It's like a premium designer calendar that used to be a Mac-exclusive product — it hasn't just been remolded for Windows, it's been delivered as a fully assembled, plug-and-play digital edition that comes with a handy little clock permanently pinned to your desk.
