XenForo Technology Intelligence

What is XenForo?

XenForo is a commercial forum software platform known for its modern architecture, responsive design, and focus on community engagement features. It powers thousands of online communities ranging from small hobby groups to large enterprise support forums with millions of members.

Created in 2010 by former vBulletin developers Kier Darby and Mike Sullivan, XenForo was built from the ground up to address the shortcomings of legacy forum software. It introduced concepts like trophy systems, user following, and news feed-style activity streams that blend traditional forum functionality with social media conventions. XenForo 2.x brought a complete rewrite with improved performance and a powerful add-on framework.
