Unlike many other HTML checkers, CSE HTML Validator features an unusually powerful custom syntax checking engine that is specifically designed to check HTML, XHTML, and CSS. More information...
CSE HTML Validator Professional is a big step up from the standard edition due to some significant extras. It includes the Batch Wizard, the Configuration Editor, 180 days of free major upgrades, and more. The differences among the enterprise, professional and standard edition are listed in the following table.

1The Batch Wizard lets you easily check multiple files and/or URLs. It will generate a neatly formatted HTML report with the results. It can also check URLs and follow the links in the URLs to check an entire small to medium sized web site or part of a large one. The Batch Wizard is not included in the standard edition.
2The Configuration Editor lets you customize the validator messages, letting you change the text of many messages. You can also change the message type (for example, you can change a warning message to an error message). The Configuration Editor also lets you add your own validation messages, as well as new tags and attributes. The Configuration Editor is not included in the standard edition.
3The professional and enterprise editions can output validation messages in XML format. The standard edition cannot.
4A major upgrade is a change in version number of .1 or more, like from v11.0x to v12.0x. A minor update is a change in version number of less than .1, like from v12.02 to v12.03. All minor updates are free for both editions. Major upgrades (after the free upgrade period) are $29 for the standard edition and $49 for the professional edition. Upgrade pricing may be more if two or more major versions behind. Upgrade pricing is subject to change at any time.
5The Batch Wizard in the enterprise edition includes limit extensions and XML output. The limit extensions increase the number of targets that can be checked at one time. This is useful for large sites with thousands or even tens of thousands of pages. Note that there is no set limit to the number of pages that the Batch Wizard can check at one time as it depends on factors like computer resources (memory), the validation options settings, and the site itself. However, using the limit extension feature in the enterprise edition should significantly increase (vs the professional edition) the maximum number of targets that can be checked at one time. The XML output option allows XML formatted reports in addition to HTML.
