Useful Forks is a free Chrome plugin developed by jeremi.grenier.berthiaume that aims to increase the discoverability of useful forks of open-source projects on GitHub. This plugin provides a convenient way to list GitHub forks ordered by stars, with additional information and automatic filtering of irrelevant ones.

When you visit a GitHub repository, Useful Forks inserts a button next to the "Fork" button. Clicking on this button opens a new tab that utilizes an online tool to scan the forks of the repository. The tool applies a simple criteria: if a fork was created but never received any other activity on its main branch, it is filtered out from the results.

One of the key features of Useful Forks is the ability to share the results. You can export the results as a CSV file or simply provide people with the quick-link URL. This makes it easy to share the discovered forks with others, promoting collaboration and the reuse of valuable open-source projects.

Overall, Useful Forks is a valuable tool for developers and open-source enthusiasts who want to explore and discover useful forks on GitHub. With its intuitive interface and effective filtering system, this Chrome plugin provides a seamless experience for discovering and sharing valuable forks of open-source projects.
