Every website owner wants to have faster loading web pages and lighting fast content load for better user experience as well as for better positioning in Google search results ever since Google incorporated site speed as criteria for search rankings. As a matter of fact 80-90% of the end-user response time is spent downloading all the static components in web pages such as – images, CSS files, scripts etc. and one can cut this time effectively to cut waiting time of end-users.
For solution of this, CDN come in to the picture as they serve these static content to end-users with high availability and high performance as these CDN is actually a large distributed system of servers deployed in multiple data centers over the Internet
However, when it comes to those website owners, bloggers who can’t afford to have CDN services, well than, not all CDN services come with price tag. There are some CDN’s which requires only 5 minutes of your configuration setup and you are done with optimizing your website by reducing considerable amount of webpage loading time. Here are few CDN services which are free to be used without any cost of even a single penny.
One of the simplest and totally free service from Google to optimize and automatically speed up web pages. Once you sign up for PageSpeed service and provide with your serving and reference domains, you than send traffic to PageSpeed Service by pointing your DNS CNAME entry to
Thereafter, PageSpeed Service fetches content from your servers, rewrites your pages by applying web performance best practices and serves them to end users via Google’s servers across the globe.
This one is my favourite, as it has no unconditional or deceptive offers who after 15 or 30 days wanted to charge for their services. You just have to give them your website URL and rest will be done by CloudFlare except that you have to change your DNS nameserver entries and you are done.
One of the best thing about free CloudFlare service is that it offer you added optimization services such minified CSS, JS and HTML, gzipping the components, E-tags headersand other performance settings without any extra cost and absolutely free.
The WordPress also offers CloudFlare WordPress Plugin that ensures your WordPress blog is running optimally on the CloudFlare platform and better protection as spammers from your WordPress blog get reported to CloudFlare.
CoralCDN is a free and open content distribution network based around peer-to-peer technologies, composed of a world-wide network of web proxies and nameservers.
Usage of CoralCDN is simple, similar to previous services, you just append
.nyud.net to the hostname of any URL, and your request for that URL is handled by CoralCD. For example – append
.nyud.net to example.com like –
example.com.nyud.net, afterwards a peer-to-peer DNS layer transparently redirects browsers to participating caching proxies, which in turn coöperate to reduce load on the source web serve.
Being a commercial CDN service provider Incapsula also provide free CDN services of 50 GB/month to their users, although its 30 days trial service, after 30 days they will ask you to upgrade account, what you have to do is to ignore this notice, then you can use it for free forever with some limited features however.
