So many choices for CMSs these days. So then what do you choose if speed, security and customization are key? Headless for one. Consuming your own APIs for content is absolute key. It makes designing pages in the front-end a breeze. Leaving Ghost and Cockpit. If I then looked at the footprint and impact on server load, Cockpit definitely wins that battle.
10 Years ago I have started to check more about the online sphere and I have decided to make a website. There were a few CMS available at that time like WordPress or Joomla that you can use to have your website. At that point, I have decided to use WordPress as it was the easiest and I am glad I have made a good decision. Now WordPress is the most used CMS. Later I have created also a site about WordPress: https://www.wpdoze.com
