Both Joomla and WordPress established web design applications used by millions of websites around the world. The biggest difference between Joomla and WordPress, as stated by many who have reviewed these two content management systems, is that WordPress was originally designed as a blogging platform that later acquired CMS capabilities for more than just blogs. Joomla, however, has always been a true content management system.
