Sitefinity and WordPress solve common web content management problems but come from different worlds. While Sitefinity has CMS features, it is more of an enterprise cloud-based digital experience platform, while WordPress is a general-purpose web content management system.
Sitefinity’s CMS is part of a more extensive software suite. It has tighter integration with the tools you need to manage a mid to large-sized online platform for a business. You can still do what Sitefinity does with WordPress using plugins, but it will take time and money to set everything up, not to mention the multiple plugin vendors you have to deal with.
