15 Web Accessibility Testing Tools and Their Testing Capabilities

Today’s internet has grown magnanimously, bringing together information of all types on a singular platform. It allows users to access information quickly, making our life extremely simple. However, despite the great strides that we have made, web accessibility still remains a big question.

Web accessibility means that all websites, tools, applications, and interfaces have to be designed to make them accessible to users of all types, including those with physical disabilities such as hearing issues, visual impairments, cognitive or motor impairments, or others.

However, despite the advanced technology and accessibility testing tools available today, WebAIM’s testing found that:

• Home page complexity has increased by over 34% in the last 4 years, with 4.8% of all home pages detecting some disability error.
• Users with disabilities can encounter disability errors on every 1 in 21 home pages

As per new guidelines initiated by governing bodies across the globe, providing equal access to technology is critical for businesses. In addition, federal laws and guidelines, such as Section 508, ADA, WCAG, and others, make it imperative for any website or company to ensure web accessibility to people with disabilities.

This blog will discuss 15 web accessibility testing tools and some WCAG testing features that can help you identify and fix accessibility issues. These tools cover comprehensive testing capabilities, including web accessibility, keyboard navigation, color contrast, alternative text for images, audio capabilities, and more.

So, let’s dive in.
