Developer Richard Hickson has released an open-source macOS menu bar application designed to monitor Anthropic's Claude AI API usage in real-time. Created after frequently hitting usage limits unexpectedly, the tool provides developers with immediate visibility into their consumption patterns. The app is signed and notarized by Apple for security, addressing concerns about third-party tools accessing API data.

This utility solves a critical pain point for AI developers who need to manage costs and avoid workflow disruptions. The GitHub repository includes full source code, allowing developers to inspect and modify the application. As AI API usage grows, tools like this become essential for budget management and productivity.

The application demonstrates the growing ecosystem of developer utilities emerging around major AI platforms, highlighting how developers are building solutions to operational challenges not yet addressed by official providers.
