The BitMinter checker extension monitors your workers and provider information for them directly in your browser. It displays total and per worker hash rate, accepted and rejected work, total BitCoins and NameCoins mined, and much more information for each of your workers.
To work correctly, a valid API key must be set from your personal account with the ‘API’ perk enabled.
This extension is completely open source! You can contribute or submit bugs and feature requests here: https://github.com/colin-dumitru/BMChecker
