Next.js ADA Compliance Checker

ADA Compliance for Next.js Websites

Next.js sites are built by developers, often as product sites, SaaS marketing pages and stores, and they are usually fast and well made. ADA exposure on these sites comes from custom components and client-side behavior that build tools do not check: focus, announcements and page titles.

This Next.js ADA compliance checker runs the same engine as the Next.js accessibility checker with the ADA preset selected, so the results are measured against WCAG 2.1 Level AA. Paste a page address above to see the issues on your own Next.js site.

Next.js ADA Compliance Risks to Check First

These are the barriers most often behind accessibility complaints on Next.js sites. Each one maps to a WCAG success criterion that the scan reports.

• Same title on every route

  Client-side routes that do not set a unique page title.

  WCAG 2.4.2 Page Titled

• Custom components

  Dialogs, menus and dropdowns built from divs without roles and names.

  WCAG 4.1.2 Name, Role, Value

• Hard-coded page language

  A missing or wrong lang attribute in the root layout.

  WCAG 3.1.1 Language of Page

• Loading and error states

  Content that appears after loading or submission without any announcement.

  WCAG 4.1.3 Status Messages

How the ADA Applies to Your Next.js Site

Title III of the Americans with Disabilities Act requires businesses open to the public to give people with disabilities equal access to their goods and services. The Department of Justice states that this covers a business's web content as well as its physical locations ({ADA.gov web guidance (opens in a new tab)}). The law does not name a technical standard for private websites, so courts, settlements and demand letters tend to point to WCAG 2.1 Level AA, which is why this checker uses it.

• 3,117 website accessibility lawsuits filed in U.S. federal court in 2025, up 27% from 2024 Seyfarth Shaw, ADA Title III blog (opens in a new tab)
• 5,000+ digital accessibility lawsuits filed across federal and state courts in 2025 UsableNet 2025 year-end report (opens in a new tab)
• 1,427 of those 2025 lawsuits were against companies that had already been sued UsableNet 2025 year-end report (opens in a new tab)
• 64% of companies sued in the first half of 2025 had annual revenue under $25 million UsableNet 2025 midyear report (opens in a new tab)

None of this depends on which platform you use: a claim names the barrier on the page, not the software behind it. Read more in our ADA website compliance guide and the general ADA compliance checker.

Next.js ADA Compliance Steps

1. Run the ADA check above on your homepage, and then on a page of each type you publish.
2. Set a unique title for every route and a correct lang value in the root layout.
3. Replace custom controls with real buttons and links, or a tested component library.
4. Add accessibility checks to CI, and scan each deployed preview and the live site.
5. Rescan to confirm each fix, and keep dated records. AccessBell Pro monitors up to 500 URLs per domain every day and emails you when something new fails.

What an Automated Next.js ADA Check Can and Cannot Do

Automated testing finds a large share of the machine-detectable WCAG failures, such as missing alt text, unlabeled fields, low contrast and broken ARIA. It cannot judge whether alt text is accurate, whether a keyboard path makes sense or whether a screen reader user can complete a purchase. Test your key journeys by hand as well, and read our methodology for exactly what runs.

No tool, including this one, can certify that a Next.js site is ADA compliant or protect you from a claim. Treat a scan as evidence of ongoing effort, and speak to a lawyer if you receive a demand letter.

Free scan and 3-day free trial

Publishing an Accessibility Statement on Next.js

Add a statement route to your app and link it from the footer component, so it appears on every page. Our free accessibility statement generator writes the text, and it should name the standard you follow, any known gaps and a way to contact you.
