Your Claude Code runway, pinned to the Windows taskbar
A lightweight Rust taskbar widget that shows how much of your Claude Code, Codex, or Cursor allowance is left — and when it resets — with no backend and no telemetry.

What it does It lives in the Windows taskbar and shows, per provider, how much of your usage allowance you’ve burned and how long until the limit resets. Claude Code, Codex, Cursor, Google Antigravity, and OpenCode Go are all on the menu, with multiple accounts supported for Claude Code and Codex. Quick controls hang off the system tray; everything else — refresh interval, providers, language, startup — lives in a settings dashboard.
The interesting bit There’s no account linking and no middleman service: the widget reads the sign-in credentials already on your machine (Claude CLI, desktop app, or WSL) and polls each provider’s official service directly. Strip away the polish and it’s glue — credential discovery, API polling, a taskbar renderer — but unusually well-dressed glue, right down to a visual Theme Studio for building custom widget layouts. The usage-direction toggle (count up from zero, or watch a full allowance drain) is a small tell: it’s built for people who think in what’s left, not what’s spent.
Key highlights
- Usage and reset countdowns for Claude Code, Codex, Cursor, Google Antigravity, and OpenCode Go
- Multiple accounts for Claude Code and Codex
- Display usage counting up from zero, or as remaining allowance that starts at 100% and drains
- Built-in themes plus a visual Theme Studio for custom layouts
- No backend, no telemetry, no analytics; credentials are read without modifying the files that hold them
Caveats
- Windows 10/11 only — macOS and Linux users need not apply
- OpenCode Go credentials sit in a plain-text JSON config, which the README itself says to guard like a browser session cookie
Verdict If you run Claude Code or Codex on Windows and have ever been ambushed by a limit reset, this earns its tray space. If you’re not on Windows, or parking an OpenCode Go session cookie in a config file bothers you, pass.
