Claude Usage Tracker

Track your Claude.ai usage — messages, tokens, and conversations. Not affiliated with Anthropic.

Claude Usage Tracker Why You Should Install This Extension Anthropic's Claude is incredibly powerful, but its dynamic rate limits can abruptly interrupt your workflow. Peak hours drain your Claude session 3 to 5x faster. If you use Claude for heavy coding, research, or writing, hitting a sudden rate limit means losing momentum and context. Claude Usage Tracker is built to solve this. It gives you precise, real-time visibility into your remaining compute so you can plan your work intelligently. By tracking exactly when peak hours begin and end, you can shift heavy workloads to off-peak windows to maximize your message cap. Furthermore, the extension operates entirely locally, meaning you gain full visibility without sacrificing your privacy. What It Does This extension seamlessly integrates a monitoring dashboard directly into your browser and the Claude.ai interface. • Smart Peak Hours Monitor: Shows a live peak/off-peak banner with a countdown to the next change, so you can shift your heavy work to off-peak windows. The schedule is fetched from a public configuration file and updates automatically when Anthropic adjusts it. No extension update required. For Pro and Max plans, the banner correctly reflects Anthropic's May 2026 change: peak hours no longer impact Claude Code on those plans, only chat sessions. • Dual-Ring Toolbar Icon: The toolbar icon shows two concentric rings. The outer ring represents the 5-hour session limit, and the inner ring represents the 7-day weekly limit for all models. • Live Session Gauge: A circular gauge provides the percentage of your 5-hour Claude limit used, color-coded green to red as you approach the cap. • Per-Model Breakdown: Track All models, Opus, Sonnet, Haiku and Claude Design as stacked bars on your weekly cap. • Claude Hours Heatmap: A GitHub-style hourly grid shows when you actually use Claude across the week or the month. This allows you to spot your patterns, plan around peak hours, and work smarter. • Plan Badge: See your tier at a glance (Pro, Max 5x, Max 20x, Team, Enterprise). • Daily Routines Tracker: Monitor your scheduled Claude Code routines (Max plans, X / 15 per day). • Seamless Light & Dark Mode: The popup, tips page and update page now fully support light mode. A toggle in the header cycles between auto (follows your OS setting), light and dark. Your preference is saved and applied instantly with no flash on open. Strict Local Privacy Your conversations remain entirely private. The tracker calculates usage by analyzing DOM elements and intercepting network quota headers directly in your browser. It does not read your message content, it uses no telemetry, and it transmits zero data to external servers.
