CDNJS is a free and open source project to organize and provide popular front-end web development resources to developers via a fast CDN infrastructure without usage limitations and fees. We want to help individual library/framework developers distribute their projects, and web developers supercharge their websites! With our great free CDN service, developers can focus on their projects and website development. Developers no longer have to spend time worrying about how to set-up a CDN for projects or website assets. We hope to make web development easier, as well as your websites and the WWW faster and safer.

We really appreciate your help.
Currently, CDNJS is rated No. 2 (ref) in web front-end CDN services and has great performance. We fully support https, SPDY, http/2.0, and SRI. These will boost and secure your website with zero configuration. (Note: You'll still need to take care of server-side and application layer security issues. We make it better, but we can't help you too much if you implement a bad practice.)
latest version URL support
Note that we don't support the feature to use
latest in the URL because of the reasons below:
- Your website might break if there are any compatibility issues or bugs coming from upstream. It's not a good idea to use it in the production environment. Both jQuery CDN and Google CDN don't provide this feature.
latestURL feature also has cache and performance issues. This conflicts with what we are trying to do - make your website load as fast as possible.
latestURL feature, however, totally conflicts with the SRI technique.
