Claude Usage Tracker
Extension Actions
Tracks your Claude.ai usage limits, extra spend, and estimates API-equivalent costs over time.
Stop guessing whether your Claude subscription is worth it.
Claude Usage Tracker automatically monitors your claude.ai usage from the Settings page and builds a history over time. See your session limits, weekly quotas (all models + Sonnet), extra usage spend, and estimated API-equivalent costs — all in one popup.
Features:
- Auto-scrapes every hour (silent background tab)
- Tracks session, weekly, and extra usage percentages
- Estimates what your usage would cost at API pay-as-you-go rates
- Exports history as JSON
- Badge shows weekly usage % with color coding (green/amber/red)
- 100% local — no data leaves your browser
Works with Claude Pro ($20), Max 5x ($100), and Max 20x ($200) plans.
