Choose an existing Green-IT tool—like Scaphandre or PowerHog —and make it better! Whether it’s improved usability, more accurate measurements, new integrations, or enhanced visualization—your contribution can push the green software movement forward.

Select a tool from the Green-IT ecosystem (we’ll provide a list of candidates). Explore the codebase and identify areas for improvement. Think about:

• Accuracy: Are measurements reliable across platforms or hardware?
• Usability: Could the UX be more intuitive for developers or sysadmins?
• Performance: Is the tool lightweight and fast?
• Integrations: Could it work better with CI/CD, cloud platforms, or monitoring tools?
• Visualization: Can you present the data in a more accessible or actionable way? Implement, test, and document your enhancements.

If you don't know where to start, chose one ore more of these challenge variants:

• Blue Slope:
  • Take a green software tool
  • Learn to use it
  • improve the documentation. Submit Pull/Merge-Requests
• Red Slope:
  • Chose an existing tool and improve the working of the tool an a new or not well supported platform (e.g. port or improve windows support for PowerHog or Scaphandre)
• Black Slope:
  • Compare energy metrics of different AI metrics tools:
