Features & Capabilities

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 monitors Claude Design 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
Claude Design usage (most trackers ignore this)
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.

Is Claude Usage: Session, Weekly & Design Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Claude Usage: Session, Weekly & Design requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
