CodexBar Windows

Windows system tray application for monitoring Claude AI usage limits. Built with Tauri + React + TypeScript.

Features

• System tray icon with popup window
• Real-time Claude subscription usage monitoring:
  • Session limits (5-hour window)
  • Weekly limits (all models)
  • Weekly Sonnet limits
  • Extra usage spending
• Auto-refresh usage data

Requirements

• Windows 10/11
• Claude CLI authenticated (npm install -g @anthropic-ai/claude-code && claude)

Development

cd codexbar-windows
npm install
npm run tauri dev

Build

npm run tauri build

How it works

The app reads OAuth credentials from ~/.claude/.credentials.json (created by Claude CLI) and fetches usage data from Anthropic's OAuth API endpoint.
