Overview

Claude Usage Tracker is a lightweight, native macOS menu bar application that provides real-time monitoring of your Claude AI usage limits. Built entirely with Swift and SwiftUI, it offers a clean, intuitive interface to track your 5-hour session window, weekly usage limits, and Opus-specific consumption.

• Multi-Profile Display: Monitor all profiles simultaneously in the menu bar
• Claude Code Integration: Sync CLI accounts and auto-switch credentials when changing profiles
• Real-Time Monitoring: Track session, weekly, and per-model usage (Fable, Opus, Sonnet, Design), API console usage, and API costs per profile
• Usage History: Interactive charts tracking session, weekly, and billing data over time
• Global Shortcuts: System-wide keyboard shortcuts (no Accessibility permission)
• Headless Mode: Works on headless Macs via Remote Desktop
• Customizable Interface: 5 icon styles + 3 color modes (Multi-Color/Greyscale/Single Color) + per-element statusline colors + remaining/used percentage toggle
• Smart Automation: Auto-start sessions, auto-switch profiles, threshold notifications
• Developer Tools: Terminal statusline integration with model, context, profile display, weekly/extra usage segments, pace markers, per-element colors, and color modes
• Privacy-First: Credentials in the macOS Keychain, local storage, minimal anonymous analytics (version-only heartbeat), no cloud sync

Claude Code Integration

Bring real-time Claude usage monitoring directly into your terminal with Claude Code statusline integration! Display your current usage percentage, model name, context window, profile name, git branch, and working directory without leaving your development workflow.

What is Claude Code?

Claude Code is Anthropic's official CLI tool for interacting with Claude AI directly from your terminal. The statusline feature allows you to display custom information at the bottom of your terminal window.

Setup Instructions

Prerequisites

1. Claude Code installed: Download from claude.com/claude-code
2. Session key configured: Must be manually configured in the Personal Usage tab (Claude Code OAuth doesn't work for statusline - it requires direct session key)

Installation Steps

1. Open Claude Usage Tracker Settings

   • Click the menu bar icon
   • Click "Settings"
   • Navigate to the "Claude Code" tab

2. Choose Your Components

   • Toggle on/off the components you want to see:
     • Directory name: Shows current working directory
     • Git branch: Displays current branch with ⎇ icon
     • Model name: Shows current model (Opus, Sonnet)
     • Profile name: Shows active profile name
     • Context window: Shows context usage as percentage or token count
     • Usage statistics: Shows session percentage with color coding
     • Progress bar: Visual 10-segment indicator (optional when usage is enabled)
     • Pace marker: Colored ┃ on progress bar at elapsed time position (6-tier pace colors)
     • Reset time: When your session resets (12h or 24h format)
   • Color mode: Choose Multi-Color, Greyscale, or Single Color
   • Label toggles: Show/hide "Ctx:", "Usage:", "Reset:" prefixes

3. Preview Your Statusline

   • The live preview shows exactly how it will appear with terminal-matching ANSI colors
   • Example: claude-usage │ ⎇ main │ Opus │ Work │ Ctx: 48% │ Usage: 25% ▓▓┃░░░░░░░ → Reset: 3:45 PM

4. Apply Configuration

   • Click "Apply" button
   • Scripts will be installed to ~/.claude/
   • Claude Code's settings.json will be updated automatically

5. Restart Claude Code

   • Close and reopen your Claude Code terminal
   • The statusline will appear at the bottom of your terminal window

What Gets Installed

The setup automatically creates:

• ~/.claude/fetch-claude-usage.swift: Swift script that fetches usage data from Claude API
• ~/.claude/statusline-command.sh: Bash script that builds the statusline display
• ~/.claude/statusline-config.txt: Configuration file with your component preferences
• ~/.claude/settings.json: Updated with statusline command (or created if doesn't exist)

All scripts are set with secure permissions (755) and only read your existing session key file.

Customization

Available Components

Color Coding

Usage bar is color-coded with a 10-level gradient:

• 0-10%: Dark green
• 11-30%: Green shades
• 31-50%: Yellow-green transitioning to olive
• 51-70%: Yellow to orange
• 71-90%: Dark orange to red
• 91-100%: Deep red

Pace marker uses a 6-tier system based on projected end-of-period usage:

• Comfortable (projected <50%): Green
• On Track (50-75%): Teal
• Warming (75-90%): Yellow
• Pressing (90-100%): Orange
• Critical (100-120%): Red
• Runaway (>120%): Purple

Color modes (applies to both menu bar and statusline):

• Multi-Color: Full color palette (default)
• Greyscale: No colors, adapts to system theme
• Single Color: All elements use your custom hex color

Disabling Statusline

To remove the statusline:

1. Open Claude Usage Tracker Settings → Claude Code tab
2. Click "Reset" button
3. Restart Claude Code

This removes the statusline configuration but keeps the scripts installed for easy re-enabling.

Troubleshooting

Statusline Not Appearing

1. Verify Claude Code is installed and working
2. Check that you restarted Claude Code after applying
3. Ensure session key is valid in General settings tab
4. Check that ~/.claude/settings.json exists and has the statusline configuration

Shows "Usage: ~"

This indicates the Swift script couldn't fetch usage data:

• Verify your session key is valid
• Check that ~/.claude-session-key exists
• Ensure you're connected to the internet
• Try refreshing your session key from claude.ai

Permission Issues

If scripts can't be executed:

chmod 755 ~/.claude/fetch-claude-usage.swift
chmod 755 ~/.claude/statusline-command.sh

Example Statuslines

With all components enabled (Multi-Color mode):

my-project │ ⎇ feature/new-ui │ Opus │ Work │ Ctx: 48% │ Usage: 47% ▓▓▓▓┃░░░░░ → Reset: 4:15 PM

Compact (labels hidden, 24h time):

my-project │ ⎇ develop │ 12% ▓┃░░░░░░░░ → 16:15

Model and context only:

Sonnet │ Ctx: 96K │ Usage: 25%

1. Open Settings → Personal Usage
2. Use the 3-step wizard to reconfigure:
   • Test your session key
   • Select the correct organization
   • Save configuration
3. The wizard will preserve your organization selection when updating keys

Menu Bar Icons Showing Zero

If icons briefly flash to zero during refresh:

• This has been fixed in v2.1.0+
• Update to the latest version for smooth refresh experience
• Old data now stays visible until new data arrives

Menu Bar Icon Not Appearing

1. Check System Settings → Desktop & Dock → Menu Bar
2. Restart the application
3. Check Console.app for error messages

Session Key Expired

Session keys may expire after a period of time. You'll receive a notification 24 hours before expiry (v3.0.2+). To refresh:

1. Go to Settings → Personal Usage (or API Console)
2. Click "Sign in to Claude.ai" (or "Sign in to Anthropic Console") to re-authenticate via the built-in browser
3. Or expand "Advanced: Manual Session Key" to paste a new key manually

Updates Not Working

If automatic updates aren't working:

1. Check Settings → Updates to ensure automatic checking is enabled
2. Verify you're running v2.0.0 or later (earlier versions don't have auto-update)
