RepoLens is a free Chrome add-on designed to enhance the browsing experience by scanning any webpage for GitHub repository links. It provides instant information about the repository's status, categorizing them as alive, stale, or dead through color-coded badges, which indicate the last update time: green for recent updates, yellow for moderate activity, and red for older repositories. This feature eliminates the need for multiple clicks and tabs, streamlining the process of evaluating GitHub links.

In addition to its scanning capabilities, RepoLens offers detailed insights when hovering over the badges, displaying information such as the repository's description, topics, stars, forks, issues, programming language, and license. The tool is versatile, functioning seamlessly across various platforms including blogs, documentation, and forums, while also supporting user customization with features like dark mode and a smart cache. RepoLens is open source, ensuring no tracking or advertisements interrupt the user experience.
