  1. Contrastchecker.com – This tells you whether your page has the proper contrast ratio
  2. Chrome Extension: Accessibility Developer Tools – This is a collection of great accessibility tools created by Google specifically for developers.
  3. Capybara accessible – Capybara-accessible defines a Selenium-based web driver that acts as a drop-in replacement for Selenium or Webkit in your Capybara integration tests.

  4. Tenon.io – Tenon exists to provide reliable and accurate automated accessibility testing coverage for a wide array of accessibility best practices. Some accessibility best practices are either too subjective or too complex to be accurately tested with automated means. Doing so increases the risk of so-called “false positives”, which can reduce the usefulness of a testing tool.

Our experiences with 508 compliance testing tools

While creating section 508 compliant WordPress software and WordPress websites we have learned a few things. We have used a lot of different section 508 compliance testing tools. Some of them we paid for and some we used for free. On this page, we have included the section 508 compliance testing tools free for everyone to use. We implore all developers to take a look at this list. We know that you cannot change your process completely and we do not expect you to. As developers, if we just change a few things about our processes we usually find that it doesn’t take much more time than it did before. As we continue to build websites this would add up to a much better user experience for people who are visually impaired.

Let our mistakes be lessons to other developers or companies who are trying to become section 508 compliant. We have made mistakes by using large and cumbersome types of software trying to become 508 compliant. We have also made mistakes by purchasing some of the paid section 508 compliant plugins and other types of software.  Some of them worked well but later on, we found essentially the same 508 compliance testing plugins for free. We have also made mistakes by not understanding how easy it is to create a section 508 compliant WordPress website if we follow a few rules from the very beginning. This way as we build the site we are just making sure that everything meets or exceeds section 508 compliance laws.

508 compliance testing tools

Here is a list of guidelines to make sure your website is section 508 compliant. If you understand and implement these guidelines from the beginning of your project. The software or website that you are building will naturally be 508 compliant at the end of your project. So we hope that this can help guide you through the process.

The Guidelines for Section 508 Compliance:


  1. Provide text alternatives for non-text content (Alt Text for Pics)
  2. Provide caption and other alternatives for multimedia (Video Transcripts)
  3. Create content that can be presented in different ways, including by assistive technologies, without losing meaning (HTML tags to identify reading sequence)
  4. Make it easier for users to see and hear content (Use of color, contrast ratios, text links must make sense when read out of context)


  1. Make all functionality available on the keyboard (HTML tags, correct tab order)
  2. Give users enough time to read and use content ( Minimize timing of content, give users control)
  3. Do not use content that causes seizures (No scrolling text, ability to pause or control speed of rotating banner ads)
  4. Help users navigate and find content (Sitemap accessible from every page)


  1. Make text readable and understandable (Minimize jargon and acronyms, adjustable text size)
  2. Make content appear and operate in predictable ways (Consistent navigation)
  3. Help users avoid and correct mistakes (From form field labels, user-friendly error messages, confirmation of form submissions)


  1. Maximize compatibility with current and future user tools (Proper coding, standard HTML)
