Claude Usage Bar

A SwiftBar plugin that shows your Claude.ai usage in the macOS menu bar — session (5-hour window) and weekly limits, live.

No API keys. No tokens. Reads directly from your already-logged-in browser.

---

What it shows

• Menu bar: current session usage % (color-coded: blue → yellow at 70% → red at 90%)
• Dropdown: session progress bar + time until reset
• Dropdown: weekly progress bar + time until reset

---

Install

1. Install SwiftBar if you haven't:

brew install --cask swiftbar

2. Download the plugin:

curl -o ~/your-swiftbar-plugins-folder/claude-usage.1m.py \

chmod +x ~/your-swiftbar-plugins-folder/claude-usage.1m.py

Or just clone this repo and copy the .py file to your SwiftBar plugins folder.

3. Make it executable:

chmod +x claude-usage.1m.py

That's it. No configuration needed.

How it works

SwiftBar runs the script every minute. The script uses AppleScript to execute a XMLHttpRequest inside your open claude.ai browser tab — calling Anthropic's internal /api/organizations/{id}/usage endpoint with your existing session. The response is parsed and displayed.

Your credentials never leave your machine. The script does not store session tokens.

---

Privacy

• Runs entirely on your Mac
• No external backend
• No telemetry or analytics
• No API keys, cookies, or session tokens are sent to the author or any third party
• All requests are made locally from your machine using your own logged-in Claude session

Troubleshooting

✦ with no number — claude.ai tab not found. Make sure it's open and you're logged in.

✦ ! — unexpected error. Click the icon to see details.

Wrong Python path — the shebang line uses /usr/bin/env python3. If python3 is not on your PATH:

which python3
# then edit the first line of claude-usage.1m.py

Permission denied — run chmod +x claude-usage.1m.py
