Claude Usage Monitor

Claude Monitor shows how much Claude you have left before you hit a usage limit. A badge in your browser toolbar tracks your 5-hour session and weekly limit live, with a countdown to every reset and desktop alerts at 80% and 95%. One click opens per-model weekly caps, extra-usage credits in real money, Claude Code routine runs and 30 days of history you can export.

It works on the Free plan, where Claude stopped showing usage in August 2026. Turn on the optional bar and the limits sit right above the chat box, in claude.ai and in Claude Code on the web.

Free, open source (MIT), no account, no telemetry. For Chrome, Firefox and Edge, in 8 languages.
