Translation CDNs Frameworks
CDNs (Develop branch) Frameworks (Develop branch)

LocalCDN is a web browser extension that emulates Content Delivery Networks to improve your online privacy. It intercepts traffic, finds supported resources locally, and injects them into the environment. All of this happens automatically, so no prior configuration is required. Feel free to use the following testing utility to find out if you are properly protected. For more information, please look at the graphic below or read the tutorial or our Wiki pages. You can also download the extension directly from Mozilla and just try it.

LocalCDN supports over 100 Libraries and 27 CDNs!
