Evaluation tools (also known as "accessibility checkers")

According to the W3C Web Accessibility Initiative, evaluation tools "perform a static analysis of [web] pages or sites regarding their accessibility, and return a report or a rating." Note that evaluation tools may be client-based (authors voluntarily use them for checking their work) or server-based (the server generates advisory reports of compliance errors to a system administrator as well as the page owner). Tools vary on their ease of use, methods of detecting and reporting errors, and price. Most products have a free demonstration available to help you decide before buying. Of the many tools available, a summary of popular ones follows.
