Our high-end product is CSS HTML Validator Enterprise. This edition includes everything CSS HTML Validator has to offer, including priority support and maintenance (PS&M) and a Batch Wizard that has more features and is capable of handling larger jobs.
Visit the Priority Support & Maintenance page for more information about the included PS&M. NOTE: PS&M is only included with the enterprise edition but is available as an added option with the home/standard and pro editions.
Our basic paid product is CSS HTML Validator Home. This product provides the same syntax checking thoroughness as higher editions, but doesn't include some features, like the Batch Wizard. This edition was previously named CSS HTML Validator Standard.
