Show HN: Mac menu bar app for Claude Code rate limits (github.com)

A new macOS menu bar app, ClaudeWatch, has been unveiled to help users monitor their Claude Code usage and the operational status of the Anthropic service. This native application provides real-time updates on usage metrics through a statusline hook, which logs data such as five-hour and seven-day token usage percentages and service health directly from terminal sessions. By automatically updating a JSON usage file, the app ensures users can efficiently track their consumption without directly querying the Anthropic API. This tool is significant for the AI/ML community as it streamlines the management of Claude Code resources, allowing developers to optimize their usage within defined rate limits. Built using Swift 5 and SwiftUI, ClaudeWatch is compatible with macOS 14 Sonoma and newer, comes with zero external dependencies, and offers customizable alerts regarding service fluctuations. Its integration with the terminal enhances usability by displaying critical performance metrics, ensuring that users can maintain efficient workflows while employing Claude Code.
