What Are Web Accessibility Testing Tools?

Web accessibility testing tools are software used to evaluate and improve the accessibility of websites and web applications. They test for compliance with accessibility standards like the Web Content Accessibility Guidelines (WCAG), identifying elements that may hinder access for users with disabilities. These tools check various aspects such as color contrast, keyboard navigability, and screen reader compatibility, ensuring that web content is accessible to a diverse range of users.

The benefits and uses of web accessibility testing tools include making websites more inclusive for individuals with disabilities, such as visual, auditory, motor, or cognitive impairments. They help in meeting legal requirements and ethical standards for web accessibility, reducing the risk of non-compliance penalties. By improving website accessibility, these tools enhance the user experience for all visitors, expand the potential audience reach, and positively impact the brand's reputation.

I've been using and reviewing accessibility tools for websites for years so you can trust me to do the heavy lifting and compile all the facts you need to make your final decision.

Selection Criteria

After careful consideration, I've determined that these are the most important criteria when selecting the best web accessibility testing tools. Here's a brief list outlining the whats and whys of my selection.

User interface is an important factor to consider when choosing web accessibility testing tools because it directly affects the usability and effectiveness of the tool for the tester.

Usability is a crucial factor to consider when selecting web accessibility testing tools because it impacts the effectiveness of the tool in identifying accessibility issues.

Software integrations are essential when selecting web accessibility testing tools because they enable the tool to work seamlessly with other software applications in the development process. The integration of accessibility testing tools with other software tools, such as code editors, content management systems, and development frameworks, can help developers identify and fix accessibility issues early in the development process. This saves time and effort in testing and fixing accessibility issues, resulting in a more accessible and inclusive website.


Pricing is an essential factor to consider when selecting web accessibility testing tools because it can significantly impact the overall cost of the development process. While it is crucial to ensure that a website is accessible to all users, it is also important to do so within budget constraints. Pricing considerations for accessibility testing tools include the upfront cost of the tool, ongoing maintenance and support fees, and the cost of any necessary integrations. Additionally, some tools may offer different pricing plans depending on the size of the organization or the number of websites being tested.
