Usage4Claude 3.0.0: Open Source macOS Menu Bar Tracker for Claude and Codex
Usage4Claude is a native macOS menu bar app that tracks Claude subscription usage. Version 3.0.0 adds optional Codex support, built-in browser login for Claude, multi-account switching, and localized notifications.
Key Features
- Displays current usage limits in the menu bar: Claude shows 5-hour, 7-day, Extra, 7-day Opus, and 7-day Sonnet limits when available.
- Codex (optional) shows 5-hour, 7-day, and Extra Usage credits side by side with Claude.
- Built-in browser login for Claude — no manual cookie/session digging required.
- Multiple Claude accounts and organizations supported, plus separate Codex account switching.
- Notifications at 90% usage and on usage reset.
- Stores auth in macOS Keychain — no analytics, only usage-related requests.
- Localizations: English, Japanese, Chinese, Korean, French.
Technical Details
Built primarily with Claude Code as the coding partner, handling SwiftUI work, refactors, localization passes, and edge cases around refresh state. The app is open source and independent — not affiliated with Anthropic or OpenAI.
Who It's For
Developers using both Claude and Codex who need a quick, local usage overview without leaving the menu bar.
