What is a website accessibility checker?
A website accessibility checker tests a page’s code and content automatically and reports what fails. WCAG, the standard it tests against, sets out four principles: perceivable, operable, understandable and robust. Together they ask whether people can see and hear your content, move through it, make sense of it, and open it in the software they rely on. The Nexus Inclusion free accessibility checker tests each POUR principle that can be verified in code, against WCAG 2.2 Level AA.
Perceivable
Can people see and hear the content?
We check things such as text alternatives on images, contrast between text and what sits behind it, captions on video, and whether meaning is carried by colour alone. These are the failures we see on most websites.

Operable
Can people use the controls?
We check whether everything can be done using a keyboard, whether it's clear where the focus is, and whether anything traps focus.

Understandable
Is it clear what is happening?
We check whether the page declares its language, whether form fields have proper labels rather than placeholder text, and whether errors are announced instead of only shown visually.

Robust
Will assistive technology interpret the page correctly?
We check if the page’s code is structured in a way assistive technologies can understand, like whether ARIA has been used correctly.

What does the free accessibility check cover?
The free check tests your homepage against WCAG 2.2 Level AA and emails you the result.
You get an indication of your compliance status against that standard, and a count of every issue found, graded critical, high, medium or low, so you can see the scale before deciding what to do about it. The report then divides those issues two ways.
Users affected: Visual, hearing, mobility, cognitive and neurodivergent impacts are counted separately, so the numbers describe people rather than just code.
Relevant WCAG principle: Which of the four WCAG principles is weakest. This allows you to organise and prioritise your fixes.
No account, no card needed.
What to do with your results?
The full report shows how many issues you have, their severity, who they affect, and which WCAG principles need attention.
What you do next depends on which result you got:
Compliant. Congratulations! That's rare on a first scan. Run a full scan to check your whole site, then turn on continuous monitoring to catch future changes. Our advanced tools can also check colour contrast, tabbing order and content.
Partially compliant. You've got a mix of good and bad. Work through the flagged issues using our Content and Media tools, then run the check again to confirm they're fixed. Once the check comes back compliant, you're ready for a full website scan.
Non-compliant. Start with critical and high-severity issues. Because they often come from repeated components, fixing one can resolve several issues at once. Run the check again, or let our team help with the remaining issues.
How Nexus Inclusion keeps your whole site accessible?
The full Nexus Inclusion platform starts where the free check ends. We test your entire website against the WCAG 2.2 Level AA standard, including your checkout, booking forms and account areas. Additionally we offer a full suite of standalone tools to support media, content and image accessibility.
Continuous monitoring retests your site daily to detect changes. We send alerts when something breaks and provide compliance reporting for your team.

Yes. No account, no card, no trial that expires. We ask for an email address if you want the full report sent to you. You can see the headline result without giving us anything.

Level AA, using WCAG 2.2. Level AA conformance includes every Level A criterion, so your report lists failures at both levels.
The full Nexus Inclusion solution check up to WCAG 2.2 and global compliance standards, including EAA, ADA, Section 508, UK regulations, and more.

No. This tool analyses and gives an indicative compliance status of your homepage. Only a full website accessibility audit can determine whether your site is in accordance with global accessibility regulations.
To achieve full compliance and be digitally inclusive use our full suite of tools or we can help you with dedicated accessibility support.

Because checking one page keeps the scan free and instant, while a whole-website scan takes more time and effort. Your homepage tells you the state of your shared components, which is the fastest useful signal we can give you in thirty seconds.

No, and that is deliberate. Cookie banners and pop-ups sit on top of your page, and most are supplied by a third party rather than written by you. If we tested them, their problems would land in your results and bury the ones you can actually fix. We suppress them before the check runs, so what comes back is about your homepage.
Your banner still matters. It is the first thing many visitors meet, and it needs to work for someone using a keyboard. Tab into it and back out again. If you cannot escape it, that is a real barrier. Raise it with whoever supplies it, or ask us to take a look with you.

It depends where you operate and what you do. Most accessibility laws either name WCAG as its technical standard or embeds it, though the version differs from one regime to the next. This check tests WCAG 2.2 Level AA, which covers the earlier versions those laws name.
EU — the European Accessibility Act had to be in national law across all 27 member states by 28 June 2025.
UK — the Public Sector Bodies Accessibility Regulations cover the public sector; the Equality Act 2010 covers service providers more broadly.
US — the ADA applies to state and local government and to places of public accommodation; Section 508 applies to federal agencies and what they procure.
Canada — the Accessible Canada Act covers federally regulated organisations; Ontario's AODA covers the public sector and private organisations with 50 or more employees.
Australia — the Disability Discrimination Act 1992 applies without naming a technical standard.
New Zealand — the Web Accessibility Standard applies to mandated public service agencies.

Automated checks quickly and reliably identify accessibility issues. They analyse what is detected in code, which is the starting point for digital accessibility. The Nexus Inclusion platform takes it from there: every page tested, tools to fix what comes back, monitoring to keep it fixed, and our own accessibility team on hand to make your site genuinely accessible and inclusive.
-
Ours, obviously.
The best solution should name the standard it tests against, be clear about how serious each problem is, guide you on how to fix them, and not stop at a single page. This free check does the first two, on your homepage.
The Nexus Inclusion Platform does all four across your whole site and keeps testing as it changes.
