jsDelivr CDN features

MAXIMUM PERFORMANCE AND UPTIME

Our public CDN is built with performance and reliability in mind. Everything is optimized and being constantly improved to offer all users maximum speed and uptime. Performance is monitored at all times, and we are always looking into new technologies and providers that may further improve our CDN.

Downtime, timeouts and slow responses are simply unacceptable. The idea is not to simply offer a public CDN, but to offer the best possible experience and a rock-solid product ready to be used in production by any website.

VERSION ALIASING

Every single project hosted by jsDelivr supports advanced features such as version aliasing. It allows people to use a dynamic URL and keep their websites up-to-date without changing anything. Full documentation.

AUTOMATED UPDATES

jsDelivr can automatically keep a project up-to-date as new versions are released, thanks to a bot called libgrabber that runs independently and scans for new versions of hosted projects every 30 minutes. Full documentation.

A REAL API

You can request exactly what you need using our API without downloading a huge JSON package. And it also supports cdnjs, Google Hosted Libraries, and BootstrapCDN. This way developers have everything they need to build their applications. Full documentation.

LOAD MULTIPLE FILES

jsDelivr is the first CDN to support this kind of functionality. You can load multiple files using a single HTTP request. It's similar to combining and minifying JavaScript files in your own server, but cached by the huge and smart network of jsDelivr.

All you have to do is to build your own URL with the projects and files you want to combine and their versions if needed. Full documentation.

HTTPS AND SPDY

Security is very important to all of us. Thats why all files are accessible via HTTPS with full SPDY support for better performance.

OPEN SOURCE

jsDelivr is a non-profit project with all of our software open sourced and available at GitHub for anyone to use and contribute.

UNLIMITED TRAFFIC

Thanks to our sponsors, we have absolutely no traffic limits. Even if your website generates huge amounts of traffic every day.
