What is WAVE Web Accessibility Evaluation Tool?

WAVE is a suite of evaluation tools that helps authors make their web content more accessible to individuals with disabilities. WAVE can identify many accessibility and Web Content Accessibility Guideline (WCAG) errors, but also facilitates human evaluation of web content. The vendor, WebAIM who offers WAVE as a free suite of tools, states their philosophy is to focus on issues that they know impact end users, facilitate human evaluation, and to educate about web accessibility.

The online WAVE tool can be used by entering a web page address (URL) in the field above. WAVE Chrome, Firefox, and Edge browser extensions are available for testing accessibility directly within a web browser - handy for checking password protected, locally stored, or highly dynamic pages. They also have a Accessibility IMpact (AIM) service, subscription WAVE API, and a stand-alone WAVE API and testing engine for collecting data on many pages. For enterprise-level reporting and tracking of accessibility, WAVE powers the Pope Tech accessibility tool.

The WAVE Browser Extension
The WAVE Chrome, Firefox, and Edge extensions allows users to evaluate web content for accessibility issues directly within a browser. Because the extension runs entirely within a web browser, no information is sent to the WAVE server. This ensures 100% private and secure accessibility reporting. The extension can check intranet, password-protected, dynamically generated, or sensitive web pages. Also, because the WAVE extension evaluates the rendered version of your page, locally displayed styles and dynamically-generated content from scripts or AJAX can be evaluated.

The WAVE API allows automated and remote accessibility analysis of web pages using the WAVE processing engine. Users send the URL or content of the page to be analyzed, and WAVE sends back useful data about how accessible it is. The API engine evaluates the user's web page after CSS and JavaScript has been applied resulting in a very accurate evaluation of end user accessibility.

The would-be user registers for a new API key and can purchase WAVE API credits. All new accounts get 100 free credits. Additional credits are available for as little as $.025 each. The more purchased, the less expensive credits become. For those with APIs, the user performs a simple GET request that contains an API key and the URL of the page to check, and WAVE sendS back results data in either JSON or XML format. It can be customized to get more or less data.

Pope Tech - Powered by WAVE
Pope Tech is an enterprise-level web accessibility evaluation system based on WAVE. This tool helps organizations large and small significantly improve their web site accessibility for people with disabilities by providing monitoring and reporting of accessibility over time.

We use this for very basic accessibility testing for our websites and applications and is by no means a comprehensive breakdown of the state of accessibility.
  • Identifies contrast errors
  • Identifies skipped headings
  • locates hidden or empty containers
  • It uses pt VS px. Nobody outside of print is using pt
  • It has some tools and they are incomplete at best
  • misidentifies inputs as needing labels (like a submit which does not require a label)
This is pretty middle of the road. It does a good job of picking out some of the low-hanging fruit, but it's not going properly evaluate semantic structure and will pop several false positives. Additionally, the tools are incomplete. For instance, the contrast editor will allow you to test your colors with sliders so you can get the closest color that passes; however, that isn't how color palettes work, you generally don't get to change a companies palette without a lot of pain; furthermore, there is no ability to adjust the font-size and both font-size AND color are used to determine contrast requirements. Oh, and they use points VS pixels...nobody is using points on the web even if the ADA uses them in their fairly dated guidelines. Text from the actual contrast editor "Text is present that has a contrast ratio less than 4.5:1, or large text (larger than 18 point or 14 point bold) has a contrast ratio less than 3:1.". 14pt = 18.66 pixels, so I can see their logic even if I don't agree with it.

It addressed accessibility concerns on our website and let us know what we needed to fix in terms of things like alternative text, color, contrast. It helped us look at our website as a whole and go one by one through sections. It was very easy to run the report and discover.
  • Provides report of errors for you
  • Explains what needs to be fixed so you know why
  • Shows the errors next to each item on your website so you can see which one they mean
  • Help provide you to resources to fix your website
  • Have the website look a little more detailed, it is very plain
  • Have people that work to help you make changes to your website
The tool is suited if you just created a website for your organization and want to be sure it means all accessibility guidelines. It is not appropriate for making those changes for you automatically. You need to do it manually and keep running reports to see if it is fixed.
  • The summary
  • The details where it outlines errors
  • Conrast
  • It has led us to be more inclusive and accessible in our website
  • We have more website visitors
  • We have had positive comments about our website in terms of being accessible
The other tools would be a little better than WAVE Web Accessibility Evaluation Tool. They do require you to pay for their services but offer more support on a daily basis so I would say it would be worth the money. However, I could not go ahead with the websites because they don't work with websites created on GoDaddy Managed Websites and I had to go with WAVE Web Accessibility Evaluation Tool.

I routinely use the WAVE Web Accessibility Evaluation Tool browser extension to check accessibility for web pages and web content. I primarily use it to give vendors a clear and understandable way to see the accessibility errors in their websites as well as in content they want us to embed on our websites. The tool helps us keep our partners meeting at least the bare minimum for accessibility.
  • Easy to use
  • Easy to read and understand
  • Free to use, leaving even stubborn vendors without a reason to refuse.
  • Sometimes the automated functions miss things or are mis-triggered
  • I would like it to link out to more in-depth reading on issues and resolving them
  • I would love it if it generated a PDF report to send people.
I recommend this tool all the time. It's a great, free way to, at-a-glance, gauge the basic accessibility of a web page. It catches most of the glaring issues and provides an easy way to quickly show a client or vendor where some fundamental issues are and how to resolve them. Given the price, you can't go wrong. It does not replace manual review, or even a more powerful site scanner, but it's a great, quick, foot-in-the-door to explain what accessibility is, why it matters and what some basic issues and fixes are.
  • Hosted online so I can send it, or an analyzed page to anyone
  • Free
  • Easy for anyone else to pick up and check things prior to sending on
  • Catches all of the basic issues
  • Gives basic explanations that help teach the fundamentals
  • Boosted accessibility on pages and page content across our websites
  • Allowed us to easily audit content hosted by others
  • Given us a method of requiring partners/vendors to meet basic accessibility standards.
WAVE Web Accessibility Evaluation Tool is basic and doesn't go far in depth like Siteimprove or a larger suite. It gives you a great view into exactly where basic issues are on the page, in the HTML and how to fix them. Unlike, it doesn't try to sell you promoted services and doesn't try to collect your email address, sign you up for anything or get you started on a quote with a company. It is exactly what it says on the tin and does that job with no BS.

I am the lead web accessibility specialist for the state. This tool was the first automated plugin I ever used during accessibility testing. I use this to spot-check specific web pages as well as automated testing for smaller-scale sites. I also strongly encourage any of our testers to use this as the automated testing component of their testing process.
  • Creates a great visual display of where the error is located, both in HTML source and page view.
  • An excellent option in the contrast checker is to select the color slider to locate a color that will pass accessible.
  • Clearly displays the alt text of images to check that it makes sense and is accurate
  • Great at indicating if an error is visually hidden but in the code.
  • Clean, organized, easy-to-understand details report
  • Have it check for ARIA errors
  • Indicate whether errors are A, AA, etc.
  • Have the ability to set the accessibility standard level
  • Quick export of report
I personally think WAVE Web Accessibility Evaluation Tool has the best-simplified interface of any automated checking tool. For this reason, I think this is the best for someone who is just learning how to review and read accessibility errors. It is obviously well suited if you don't need to run through a ton of pages at once. It's best for spot-checking or checking smallish sites. It works well if you don't need to export any type of accessibility report. It is ideal for someone who can go along and make the changes themself as they review the reports.
  • Simple, easy to understand interface so staff pick up on it quickly.
  • Quickly figure out correct color to use for contrast issues via the color slider
  • The carefully planned interface makes it great to do screenshots to share with someone to let them know where the error is
  • It's great at explaining what the error is and what it means.
  • It is an excellent testing tool for our web applications.
  • The fact it is free gives the freedom for anyone to use it at any time without needing to budget a tool.
  • It is a longstanding, trustworthy product.
For this, I'm speaking specifically to the Siteimprove browser plugin. The Siteimprove plugin: Allows to filter on guideline level Catches a few more errors than WAVE Web Accessibility Evaluation Tool, but comes pretty close But, both do a great job in all other aspects WebAIM shines in its simplicity of overlaying of errors and warnings on the page. I think its real benefit is a lower learning curve on understanding how to use the tool
