There are several "awesome lists" on GitHub that curate and collect the best resources for a specific programming language, framework, platform, etc.
Those lists are excellent, but when it comes time to find a package or library, they are pretty difficult to use. You'll end up having to go to every repo page to find ones that aren't abandoned, see how many stars they have, check their license, etc.
This site builds on top of those lists, but only shows repos and lets you filter by category, license, time last committed.
You can also see the number of stars and view the readme without ever leaving the page!
