In mature markets like Web Content Management, there is almost always a single proprietary leader and a single Open Source leader. There is Oracle and MongoDB. Splunk and Elastic. VMWare and Docker. Gitlab and Github. That is why I believe that next year it will be Acquia and Adobe at the very top of the WCM Magic Quadrant. Sitecore and Episerver will continue to fight for third place among companies who prefer a Microsoft-centric approach. I was not surprised to see Sitecore move down this year as they work to overcome technical product debt and cloud transition, leading to strange decisions like acquiring a services company.
WHY IT MATTERS: this analysis is spot on. There are 2 main platforms for large enterprises, Adobe and Acquia. I find the rise of episerver in the Microsoft area, from an ecommerce company into a full web platform very much worth taking notice.
