CSE HTML Validator Std/Pro is a professional web developer's tool and is much more powerful than CSE HTML Validator Lite. Therefore, it is not free like the lite edition and you will need to buy a license to use it after the trial period. For evaluation purposes, CSE HTML Validator Pro is free for 30 days or for the first 100 validations, whichever comes first. After the trial period, you must register the software by buying a license to use it. The price for a license to use CSE HTML Validator Pro is $129. The price for a license to use CSE HTML Validator Standard is $69.

To buy a license when using the trial version, simply go to Help->Buy Now. You can also order online. Please visit the CSE HTML Validator Ordering Information Page (new window) to order online. You can also find out about any discounts that may apply to you. If you are a student, non-profit organization, or educational institution then you may qualify for a discount. Note that the price may change for future versions and that you will only be able to purchase the latest version at the current prices.
