Show HN: Tokemon – monitor token use with out refreshing 27 browser tabs (github.com)

Tokemon is a newly released macOS application designed to simplify the monitoring of token usage across various language model services, including Claude, OpenRouter, Amp, and Codex, by consolidating information into a single, floating overlay window. Users can track usage metrics such as daily and weekly usage stats without the hassle of switching between multiple browser tabs. The app fetches token usage data every 60 seconds using the credentials provided in a user-specific configuration file, making it both efficient and straightforward. For the AI/ML community, Tokemon addresses a common pain point: managing and monitoring multiple service tokens simultaneously. By allowing seamless integration and retrieval of usage data, it empowers developers and researchers to keep tabs on their resource consumption easily, fostering better management of API limits and costs. The application utilizes lightweight polling mechanisms, ensuring that it runs smoothly without requiring a separate server or daemon process. However, users are reminded to handle their sensitive authentication tokens with care, emphasizing security through local credential storage.
