Your Claude plan usage monitor for Windows.
🌐 Language: English | 日本語 | Deutsch | 한국어 | Français
Claude Tank is a lightweight Windows system tray app that monitors your Claude Pro/Max/Team plan usage limits in real-time.
No more surprise rate limits — see your 5-hour and 7-day remaining capacity at a glance.
- Dual gauge tray icon — 5h and 7d remaining shown as color-coded bars
- Cyber-themed dashboard — click the tray icon for a tank-style gauge popup
- Auto-login — log in to claude.ai in the built-in browser, cookies detected automatically
- Background polling — usage updates every 1/3/5 minutes (configurable)
- Threshold alerts — independent 5h and 7d alerts when remaining drops below a set level
- Encrypted credentials — session key stored with Windows DPAPI
- Auto-start — optional launch on Windows startup
- Multilingual — English, Japanese, German, Korean, French (auto-detected from OS)
- Tiny — ~2MB exe, ~20MB RAM, no installer needed
- Windows 10 (1903+) or Windows 11
- Microsoft Edge WebView2 Runtime — usually pre-installed on Windows 11, but not guaranteed. If the app fails to start, install the Evergreen Standalone Installer from the link.

claude-tank.exefrom Releases - Run it — a browser window opens for claude.ai login
- Log in normally (Google, email, SSO)
- Done! The tray icon shows your usage gauges
Claude Tank uses the same internal API as browser extensions like claude-counter and Usage4Claude:
GET https://claude.ai/api/organizations/{orgId}/usage
Session cookies are obtained via an embedded WebView2 window — same approach as Usage4Claude on macOS.
Requirements: Rust (stable)
