Although LocalCDN has included many frameworks, it is not complete and many less popular frameworks are probably not included.
In addition, manually checking each website to find out whether a framework/CDN combination is missing and then reporting it to the developer requires much work and time.
To include as many frameworks as possible, I think we can check cdnjs' repo.
That being said, there are nearly 4000 entries in
cdnjs/ajax/libs/, so including all of them may require a lot of storage space.
