Claude Usage: Session, Weekly & Design de msadofschi

Track your Claude.ai usage in real time. See session and weekly limits, reset times, and color-coded progress — in your toolbar.

The only Claude usage tracker that shows Claude Design and per-model weekly limits (Opus, Sonnet) alongside your 5-hour session and 7-day weekly limits — all in your browser toolbar.

Stop opening claude.ai/settings/usage. A color-coded badge tells you at a glance whether you can keep working or need to pace yourself, with countdowns to every reset.

No account, no API key, no data leaves your browser. Reads your existing Claude session the same way the official settings page does.

WHAT YOU SEE
- Session usage (5-hour rolling window) with reset countdown
- Weekly usage (all models combined) with reset day/time
- Opus weekly usage (per-model weekly sub-limit, on paid plans)
- Sonnet weekly usage (per-model weekly sub-limit, on paid plans)
- Claude Design usage (most trackers ignore this)
- Show or hide each per-model card from the Models menu (with Select all / Deselect all)
- Your Claude plan shown as a badge in the header (Max, Pro, Team, etc.)
- Paid extra credits used vs. monthly cap (when enabled on your plan)
- Inline banner when your claude.ai session expires — last-known data stays visible
- Toolbar badge: green under 50%, yellow 50 to 80%, red above 80%
- Configurable auto-refresh: 1, 2, 5, 10, or 60 minutes

WHO IS THIS FOR
Claude Pro, Max, and Team users who hit limits and want to plan their work. Especially useful for Claude Code users on Max plans and teams using Claude Design.
