KeyCDN Review: The Perfect CDN For WordPress

KeyCDN is a service of Proinity Ltd, Swiss company, with its headquarters located in Winterthur. KeyCDN offers high performance Content Delivery Network packages at a very competitive price. In this KeyCDN review, we will scrutinize every aspect of KeyCDN’s offering in order to validate the claims of the company and examine the performance of the content delivery network.

In order to understand the importance and excellence of this network, certain questions need to be answered first.

What is a Content Delivery Network or CDN?

CDN is a system of servers spread over the world in multiple data centers across the internet. These servers connect you to the nearest point of presence or POP and helps improve the speed of your connection. It serves almost all sections of the internet. It includes all web objects, downloadable objects, applications, live streaming media, social networks and so on.

Why do you need CDN?

CDN is beneficial to you in a number of ways

  • It accelerates your content.
  • It will allow you to scale seamlessly as it reduces operational costs.
  • If you have a close POP, it reduces loading time, lower latency and minimized package loss.
  • It will reduce the load on your server, thereby giving your site visitors a seamless browsing experience.

What You Get With KeyCDN

KeyCDN are not claiming they are the best Content delivery network in the market, their unique value proposition is competitive pricing. KeyCDN offers the lowest price you can find on the market, I would avoid tagging it a cheap CDN as that could be mistaken for poor performance but it certainly wins in the competitive pricing category.

Shared SSL

KeyCDN offers every customer shared SSL for free.

Custom SSL Certificate

If you already have your own SSL certificate, it is integrated for free and if you need a custom SSL from KeyCDN,  it is priced at $29/year.

KeyCDN Review

Tests carried out using

  • Large file download tests the best services for larger file downloads (e.g. video streaming)
  • Small file download tests the fastest services for a web app or website (web pages typically consist of many small files)
  • Network latency tests the overall responsiveness of a service and is generally most affected by geographical proximity

Apart from the performance test carried out through Cloudharmony we also deployed KeyCDN on this website for the purpose of this KeyCDN review and the results were pretty impressive. Compared to the Jetpack free photon CDN, we experienced faster page load and a significant reduction on server load when using KeyCDN.

    Thanks for the article. I’m really happy with KeyCDN. Speed and pricing is great!

    • WpSeer

      Thanks for contributing to the post Tom. KeyCDN is really doing a good job.

  • Moham

    I’m just using free CDN from cloudflare because my web hosting provide it,

    • WpSeer

      KeyCDN can be combined with cloudflare for a more efficient performance.

  • littleguy

    What happens when a user uploads a big file, and it takes a couple of minutes for KeyCDN to catch up, right? And until then everyone visiting the site will get an “image not found error”..??

    • WpSeer

      If you are using a pull zone, as long as the zone is fully provisioned, all your files would be served instantly.

  • George

    Now CloudFlare is on the top with universal free SSL

    • Brian Jackson

      KeyCDN can be combined with cloudflare for a more efficient performance.

      • Solomon Ndvr Kleinsmith

        Why would you want to use two? Your post says KeyCDN has free SSL too…

        Has anyone done any decent speed testing between the two?

        • Brian Jackson

          Some people prefer Cloudflare for DNS side of things. For CDN portion, it would be better just to use one or the other. In my personal experience, I have seen horrible TTFB with Cloudflare. I actually have a draft post of Cloudflare vs KeyCDN. Need to finish it writing it :) I actually haven’t seen any good blog posts comparing the two yet. And yes, KeyCDN has free shared SSL. And then custom SSL integration is free.

          • Solomon Ndvr Kleinsmith

            Yeah, a data-driven comparison between them would be great. I did some similar testing between WP hosts a few weeks back, and was surprised that cheaper hosts did better than more expensive, bigger name managed WP hosts (Lightning Base [$10/mo] did better nationally, while Flywheel [$15/mo] did better in the NY, NJ, VA area), or at least the ones under a hundred plug bucks a month.

            Finish it and share :)

            BTW, I just tried to subscribe to your blog by email and the email subscribe widget wasn’t working. I followed you on Twitter though ( @ Ndvrer ), and added you to one of my WordPress lists.

          • Brian Jackson

            Ya, I have been moving some smaller clients to InMotion Hosting and was blown away by the speed. And they are one of the only independent ones left not owned by EIG. I have yet to try Flywheel, as I am pretty with Kinsta. But ya there are some cheaper hosts out there that are really doing good.

            I will finish the post up :)

            Sorry about that, I got a little over excited with caching and concatenation lol… should be working now, had to rearrange some of the files in the footer. Console was spitting up errors. Thanks for the follow!
