10 Must-Have Web Accessibility Tools in 2024

Millions of people around the world are living with some form of disability and with countless businesses relying on the web to attract and retain customers, digital accessibility has become more important than ever.

If you’re new to the world of online accessibility, it can feel quite overwhelming at first. 

Fortunately, there are a number of web accessibility tools available today that make it simple to adhere to the latest guidelines and standards. 

Before we get into the tools you should consider in 2024, let’s cover some basics. 

What are Web Accessibility Tools?

Tools for accessibility testing are built according to the Web Content Accessibility Guidelines, also known as WCAG. 

WCAG is also what acts such as the Americans with Disabilities Act (ADA) and the Accessibility for Ontarians with Disabilities Act (AODA) are based on. 

These programs and online services can easily tell you whether your website is currently catering to users with disabilities and how you can go about correcting any accessibility issues. You will also have the option to choose between automated accessibility testing tools and manual testing services, which are performed by a 3rd-party team.

Automated accessibility testing tools are ideal if you want to save time and start making changes right away. Manual testing solutions might take more time, but they’re usually more thorough and in-depth because they don’t rely on technology alone. However, whichever option you choose, you’re going to need the help of a developer to implement any changes, unless you pay for a full service that includes implementation. 

The reason why you should be picky about the tools you use is that the best accessibility solutions are always up to date with the latest WCAG guidelines, which are modified every other year.

Why You Need These Tools

There are several reasons why it makes sense to use web accessibility tools, including:

When your website isn’t accessible, you are putting a barrier between your business and potential customers. Making your site accessible to as many people as possible automatically gives you access to more customers and more revenue.

While every country’s disability act is slightly different, many leading countries are clamping down on businesses that don’t comply with the necessary digital accessibility guidelines. Failing to comply can result in costly fines and expensive lawsuits.

Another reason to prioritize web accessibility is that it enhances your brand’s image. People want to do business with brands that are inclusive and dedicated to doing good in the world. 

What You Should Test For

Once you know which web accessibility tools you want to use, you can begin testing. Here are some of the essential categories to test in:

Does your website include videos and audio? If so, it’s critical to consider how a hearing-impaired user might use your site. To ensure they can access all media, you will need to add captions to your videos and transcripts to any audio files. 

Next, you need to cater to users with mobility challenges. Not every user will navigate your site using a mouse, which means your website needs to be keyboard compatible. Make sure you check your command orders and that you know which controls are currently active. 

Then there are visually impaired users – many of them will be using your site with the help of assistive technology such as screen readers. To make this a pleasant and engaging experience, your website should have a simple navigation and content structure and any media should have captions and alternative text. Even the fonts you use and the color contrast on your site matters as some users may only have partial visual impairments. 

Lastly, there are users with cognitive disabilities. Assisting these users entails making sure everything on your site is easy to identify and understand. Forms and menus are good examples of this. 

10 Best Accessibility Testing Tools in 2024

There will always be hundreds of web accessibility tools to choose from, but we’ve put together a list of some of the best tools for testing in 2024.

1. Color Contrast Checker by AccessibilityChecker.org

When it’s difficult to distinguish between your content and the background of your site, visitors with visual disabilities are unable to use your site. This is why color contrast ratios are part of WCAG guidelines and it’s what this tool assists with.

This color contrast checker tests the colors on your site against the latest version of WCAG. Should your site not meet the necessary requirements, recommendations will be provided that will ensure you can offer users the best experience possible. 


Wave web accessibility tool

Developed by WebAIM, WAVE is an automated accessibility testing tool that helps you quickly and easily identify structural elements that might cause confusion, text sizing issues, and contrast errors.

3. TPGi

When we look at the sheer number of web accessibility tools that are available today as well as the increase in lawsuits being filed on a global scale, it becomes clear that digital accessibility is no longer a nice-to-have feature.

Luckily, you now have a solid place to start on this journey, ensuring your business and your customers reap the benefits of a more accessible website. 


While every tool is different, the top web accessibility tools take a deep look at the code of your site as well as the elements you’ve added to it, ensuring everything meets the necessary accessibility standards. Some of the elements a typical tool would evaluate include color contrast, fonts, site navigation, video captions, alternative text, and site structure.
