Show HN: Ration – see your Claude usage across terminals and brag usage (github.com)

A new macOS menu-bar application called Ration has been launched, allowing users to monitor their usage of Claude Code directly from their desktop without the need for terminal commands. Ration features a visual ring that tracks usage against a personalized budget that can be auto-calibrated from historical data or disabled altogether. It also provides detailed usage breakdowns by project and branch, along with a 7-day trend and a shareable recap card that includes metrics like streaks and estimated API equivalent costs. The significance of Ration lies in its ability to enhance productivity for AI/ML developers by simplifying usage tracking in a user-friendly manner. It operates entirely offline, reading Claude Code's session logs directly from the disk, ensuring privacy and security as no data is transmitted over the network. Ration is built using Swift and requires macOS 13+ with Xcode 16, encouraging extensibility with its provider-agnostic architecture, allowing for potential integration with additional tools in the future. This makes Ration a valuable tool for developers looking to optimize their workflow while leveraging AI tools effectively.
