Both WordPress and Joomla are content management systems (CMS). They allow you to create a website or blog from scratch, or to improve an existing site. Both platforms offer robust administrative abilities, as well as the ability to create custom templates and alter appearance through overrides. Additionally, both have built-in RSS feeds so that your readers can receive updates when new content is posted. However, there are some notable differences between the two platforms: WordPress is more focused on building blogs, while Joomla is better suited for larger publishing projects; WordPress relies more heavily on volunteers for development work, whereas Joomla has a strong community of developers behind it; and finally, WordPress emphasizes simplicity over features, while Joomla offers a greater degree of flexibility and customizability.
