The Google CDN is an awesome way to speed up page load times, but it only has a few of the most popular JavaScript libraries. That’s what CloudFlare is aiming to rectify with their CDNJS. They have a ludicrously long list of libraries—JavaScript, CSS, SWF, images, etc.—served over HTTP/HTTPS/SPDY.
Need 960gs, Twitter Bootstrap, Backbone.js, TinyMCE or something else entirely? They probably have it. If they don’t, you can open a pull request on GitHub to add it!
And since it’s backed by CloudFlare, it should be reliable. They know what they’re doing.
