“Accessibility” refers to a software system’s usability by individuals without physical disabilities or impairments and those who do. Businesses may make digital material accessible to impaired persons via web accessibility testing. Business owners must ensure that their digital material complies with the ADA and Web Content Accessibility Principles because more nations are enacting laws to open web sources to everyone (WCAG). There are an astounding 136 resources available if you check the Web Accessibility Resources List! How do you choose the right web accessibility testing tools when starting in the accessibility world?

Web accessibility testing tools are software solutions designed to evaluate websites and digital applications to ensure they can be accessed and used by people with disabilities. These tools identify issues related to standards like WCAG, ADA, and Section 508 by checking elements such as keyboard navigation, screen reader compatibility, color contrast, and semantic structure. Their goal is to help teams find and fix barriers that prevent equal access for all users.
Accessibility testing tools generally fall into these main types:
Automated Tools: Scan web pages or apps quickly to find common, programmatic accessibility issues. Examples include Axe, WAVE, and Testsigma.
Manual Testing Tools: Assist human testers with keyboard navigation checks, screen reader testing, and exploratory reviews. These might include browser developer tools and assistive technology software.
Hybrid Solutions: Combine automated scans with guided manual testing and reporting capabilities for a fuller evaluation, as seen in tools like Siteimprove and AudioEye.
Overlay Tools: Provide real-time accessibility fixes and user interface enhancements through widgets, such as Equally AI and accessiBe.
