Note: For the first three days after installation, CSE HTML Validator Lite has a count down feature on the menu that encourages you to upgrade to a commercial version if you so wish. Once the count down has reached zero, the offer expires, and the counter reverts to an upgrade link, but your software will continue to remain fully functional.

The difference between the free lite edition and the commercial editions is mostly in the detail and scope of the reports that are delivered. In addition to more thorough HTML and XHTML checking, the commercial editions also support CSS, link, and accessibility checking.
