Developed by the University of Stanford’s Online Accessibility Program (SOAP), Web Accessibility Checker is a tool that can analyze individual web pages for their accessibility. Any detected problems are listed by the tool in a report that it outputs at the end of the evaluation. The user can choose to evaluate against multiple guidelines which include WCAG 1.0 and 2.0, Section 508, BITV and the Stanca Act.
Enough Time: Users have sufficient time to read and use the website’s content. If part of the website has a time limit, users are able to turn off the time limit, or they can adjust or extend it to at least ten times the default limit (unless the time limit is essential to the website’s functionality, such as auction websites like eBay). Content that moves, blinks, or automatically updates can be paused or stopped unless it’s essential to the website’s functionality.

It works by dragging and dropping the link you wish to evaluate into your bookmarks bar to use in any browser. The program assists by displaying information within the web pages themselves, and it automatically checks specific, single web pages. Browser plugins include Google Chrome, Firefox, Internet Explorer 8 and 9, Opera 12 and 15, and Safari. Supported formats are CSS, HTML and Images, and the license is completely free for users.
The program can be run from your desktop computer, command line, or via Google Chrome or Firefox add-ons. It assists by generating reports of these five evaluation results, and reports are supported in HTML format. Browser plugins supported include both Google Chrome and Firefox. Total Validator automatically checks single web pages, groups of web pages or websites, and password protected or restricted pages. Supported formats include HTML and XHTML. The most recent version 8.5 was released on August 3, 2014, and licensing is free as well as in commercial format.
The need to make websites, mobile apps, and other online properties accessible to all is only going to increase as time moves on. Smart business owners will do well to get in front of this issue and make sure that their websites are ADA compliant now so that all their customers have the equal access to the resources they offer. Not just because they want to avoid a lawsuit or government action, but because it’s the right thing to do.

Hey Casey, this is one of the areas where things get a little weird because the W3 doesn’t actually have any say over the ADA guidelines, it is more than the ADA guidelines adopted the WCAG 2.0 guidelines as just that, a guideline to help. As far as I know, the tool you’ve linked to hasn’t been used in any judgements I’m aware of. Usually when it comes down to making a decision on if something is/isn’t compliant they have people use the actual PAWS tools and show what elements do/don’t work as intended or are otherwise inaccessible. Hope this helps!

Poorly designed websites can create unnecessary barriers for people with disabilities, just as poorly designed buildings prevent some people with disabilities from entering. Access problems often occur because website designers mistakenly assume that everyone sees and accesses a webpage in the same way. This mistaken assumption can frustrate assistive technologies and their users. Accessible website design recognizes these differences and does not require people to see, hear, or use a standard mouse in order to access the information and services provided.
