About CapMeter
CapMeter is a macOS menu-bar application designed to monitor and manage real-time usage of Claude.ai sessions, including interactions through both the browser interface and Claude Code. It operates locally by reading session data directly from the user’s encrypted Keychain, ensuring privacy and security without relying on external servers. The application displays remaining time or credits in a color-coded ring and a floating widget, providing an at-a-glance overview of usage status. It predicts when users will reach their limits based on current burn rates and sends customizable alerts via macOS notifications, Slack, Discord, or webhooks to help avoid unexpected interruptions. CapMeter supports multiple Claude accounts, allowing users to track usage across different profiles seamlessly. It also enables monitoring of weekly windows and per-model limits, offering flexibility for different subscription tiers or usage plans. Historical usage data is visualized through charts spanning 7, 14, 30, and 90-day periods, helping users analyze trends and plan their usage accordingly. Data can be exported in CSV or JSON formats for further analysis or record-keeping, and the app functions entirely offline with no servers or tracking involved.
