This is a collection of information about evaluation, repair, and transformation tools useful for Web content developers and Web users who wish to make the Web more accessible.

Please send information for tools not on this list to the public Evaluation and Repair Tools Working Group (ERT WG) mailing list, including the standard information provided with each tool. For more information about ERT WG activities, please consult the home page.

Disclaimer

Inclusion of products on this reference list does not indicate endorsement by W3C. Products are listed in alphabetical order, with no quality rating. W3C provides the information on this page as a service to the Web community and in good faith. However W3C cannot verify the accuracy of all claims made by developers or users.

How this document is organized

Tools are classified into 3 different sets:

Evaluation tools - Perform a static analysis of pages or sites regarding their accessibility, and return a report or a rating.
Repair tools - Once the accessibility issues with a Web page or site have been identified, these tools can assist the author in making the pages more accessible.
Filter and transform tools - These tools assist Web users rather than authors to either modify a page or supplement an assistive technology or browser.

There is also a list of other resources at the end of the document.

Evaluation Tools

Perform a static analysis of pages or sites regarding their accessibility, and return a report or a rating. Validation tools that check HTML and CSS without an accessibility focus are included, since validating to a published grammar is one step towards accessibility.

This list has been divided into three sub-categories:

General- Tools that perform tests for a variety of accessibility issues.
Focused - Tools that test for one or a limited aspect of accessibility.
Services - Tools that run on an ongoing basis such as proxies, Web services, and monitors.

Non-compliance with the W3C's Web Content Accessibility Guidelines (WCAG) or government standards (such as the US government's Section 508 and the UK's Disability Discrimination Act), discriminates against individuals with disabilities who should be able to access your online business, and can negatively impact your corporate brand.

Focused

aDesigner

The aDesigner is a disability simulator that helps Web designers ensure that their pages are accessible and usable by the visually impaired. Voice browsers and screen readers read aloud the text on Web pages and are used by visually impaired people. However, these devices are less effective with certain kinds of content, such as highly graphical material. Web developers can use aDesigner to test the accessibility and usability of Web pages for low-vision and blind people.

WebSAT - The Web Static Analyzer Tool uses a subset of usability guidelines to analyze a page for accessibility, form use, performance, maintainability, navigation, and readability. As with Bobby, they have automated as many of the checks as possible with many checks requiring subjective decisions by the author. It may also be run through their Web interface or downloaded and run locally on Unix or Windows 95/NT machines. As such, it may be run on a local intranet.
WebCAT - The Web Category Analysis Tool is a variation upon traditional card sorting techniques. It allows a web designer/usability engineer to test a proposed or existing categorization scheme of a web site to determine how well the categories and items are understood by users. It must be run on a local Web server (on a Unix, Solaris, or Win 95/NT system).
WebVIP - The Web Visual Instrumenter Program is a tool that can be used to conduct traditional user testing on a given set of tasks but in a rapid, remote and automated fashion. WebVIP allows the usability engineer to quickly instrument a web site for user testing. Instrumentation is accomplished through the use of visual programming and automated techniques. It must run on a local Windows 95/NT or Unix Solaris 2 server.

Testing Tools for Developing Accessible Web Sites

For those developers out there who would like to try and build an accessible site, or would like to just have some neat and useful testing tools, we have collected a few which are provided here as a service.

The Wave

A tool that helps people perform those tasks that require human judgment (e.g. "Does this ALT text a functional equivalent for this image?" "Does this reading order make sense?"). The Wave displays the ALT text of images and AREAS on the page for comparison with the images, provides numbered arrows to show the linearized reading order, and shows the HTML equivalent (if any) provided for applets. The Wave performs automatic checks (detects missing or suspicious ALT text). However, at this time it is far from covering all accessibility checkpoints.(25 Feb 2000).

Webbot - the libwww Robot

From the W3C. It is a programmable robot that can report missing "alt" attributes or other specific anomalies. Its primary design goal was to test HTTP/1.1 pipelining features. It runs locally on Unix or Windows. Users may subscribe to the discussion forum to find examples or discuss issues. (1999)

WebKing

Parasoft WebKing is a comprehensive Web verification tool that automates the most critical Web verification practices: static analysis, functional testing, and load testing. WebKing's wizards and automated technologies help you verify application functionality and reliability without writing a single script, plus its flexibility allows you to automatically verify even the most specialized requirements. You can start testing instantly, then easily extend and customize tests if needed.

Weblint

By Neil Bowers (1997). It is a syntax and minimal style checker for HTML: a Perl script which picks fluff off html pages, much in the same way traditional lint picks fluff off C programs. It is available for download on Unix, Windows NT, Mac or OS/2. Over 20 sites support a Web-based interface in a variety of languages. E-mail and a feedback form are available.

W3C CSS validator.

Validates the CSS used in documents. You may run it through the interface on the W3C server or download it and run it at a Java command line. Since it is Java it runs wherever there is a Java Virtual Machine. There is a mailing list for questions. (1998)

WDG HTML Validator

From the Web Design Group (WDG). It uses the same engine as the W3C HTML Validator (David Clark's nsgmls) but produces easier to understand error messages. It also supports a wider variety of character encodings than the W3C validator. It is available online or can run locally (supposedly, although information for running it locally was not available on 18 February 2000). You can also run a batch of pages through it. (1999)

W3C HTML validation service

It is "an easy-to-use HTML validation service based on an SGML parser. It checks HTML documents for compliance with W3C HTML Recommendations and other HTML standards." The service is available through the W3C Web site, although the source code is available for mirroring on other sites. It is known to run on Unix platforms but may work on others (it has not been tested). A discussion list is available. (2000)

TOC Maker: An add-on for Mozilla composer by Daniel Glazman. This allows you to generate a table of contents for a page, and then add it to a page or site index.

Filter and Transformation Tools

These tools modify a page or supplement an assistive technology or browser. Some of these tools integrate into the browser although most of them work by proxy: using a piece of software that sits between the user and the target server to transform a page to make it more accessible. In some cases the tools are designed for users to enhance their personal setup, in other cases they are for content providers to provide content that is particuarly optimised. The second process is similar to what is done by systems that provide web services or information services adapted to several delivery contexts - such as mobile devices, or telephone interaction. (In a sense all of these tools are also evaluation tools, since pages that can not transform in a decent way are probably broken beyond repair).

Accessibility Bookmarklets: Some javascript bookmarklets designed to perform various functions to repair accessibility problems, from Jim Ley. These are designed for Internet Explorer 5.5 but may work in other Javascript-enabled browsers. (added 3 September 2002)
