There are a number of Web Accessibility tools that can be used here is a checklist of these tools
Accessibility validation tools: These tools automatically check web pages against various accessibility guidelines and standards, such as the Web Content Accessibility Guidelines (WCAG) and the Section 508 guidelines. Some examples include the WAVE tool, the aXe browser extension, and the HTML_CodeSniffer.
Screen readers: These software programs can read the text on a web page out loud, making it accessible to users who are blind or have low vision. Some popular screen readers include JAWS, NVDA, and VoiceOver.
Color contrast checkers: These tools can help ensure that the contrast between text and background colors is sufficient for people with visual impairments. Some examples include the WebAIM Contrast Checker and the Color Contrast Analyzer.
Keyboard navigation testers: These tools can help ensure that a website can be used with just a keyboard, which is important for users who can’t use a mouse or other pointing device.
Browser extensions: There are various browser extensions that can help you to check web accessibility such as Accessibility Insights for Web, NoCoffee, and Accessibility Developer Tools.
Manual testing tools: Some accessibility features can only be tested by manual testing such as testing the website with a screen reader, keyboard-only navigation, and testing with a keyboard, mouse, and trackpad.
It’s important to note that while these tools can be very helpful in identifying potential accessibility issues, they are not a substitute for manual testing and evaluation by a person with knowledge of accessibility principles.
In summary, there are several tools available to help ensure web accessibility, including accessibility validation tools, screen readers, color contrast checkers, keyboard navigation testers, browser extensions, and automated and manual testing tools. These tools can be useful in identifying potential accessibility issues but should be used in conjunction with manual testing and evaluation by someone with knowledge of accessibility principles.
