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.

Let’s Encrypt

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.
