React accessibility,
tested in a real browser.

A WCAG 2.2 scanner for React apps. It renders your routes in Chromium, runs your JavaScript, and tests the DOM your users actually get.

No signup · 10–30 seconds

What we usually find on React.

  • Route changes nobody hears

    Client-side navigation that changes the page without telling a screen reader.

  • Modals that leak focus

    Dialogs without a focus trap, a name, or a way back to where you were.

  • Updates without live regions

    Toasts, results and errors that appear without being announced.

  • Clickable divs

    onClick handlers on elements a keyboard can’t reach or activate.

  • Component library gaps

    Library components used without the labels or roles they need.

  • Focus styles reset away

    CSS resets that remove the focus outline everywhere.

React accessibility fixes, with code.

In a React app most failures are in behaviour — focus, live updates, generated ids — not in the markup you wrote. These guides cover the common ones, with the WCAG criterion and the code fix.

How the scan works.

  1. Paste your URL

    Any public route of your app, or a preview deployment.

  2. We render it in a real browser

    Chromium loads the page with your app’s code, then runs 100+ checks against WCAG 2.2 A and AA — usually in 10–30 seconds.

  3. Fix with the evidence in front of you

    Each issue shows the element, where it is on the page and how to fix common cases.

Questions

Can ADAGuard test single-page React apps?

Yes. It loads the app in Chromium, waits for it to render, and tests the resulting DOM against WCAG 2.2 A and AA.

Does it test Next.js server-rendered pages, or only after hydration?

After hydration — the page a user actually gets. Server-rendered HTML can look accessible and still break once React hydrates: a client component replaces a labelled element, ids generated on the server and the client don’t match (use React’s useId), or focus and aria-expanded state only exist in client code. Scanning the hydrated page catches both the server markup and what client components change.

Can ADAGuard run in my CI pipeline?

Yes. The GitHub Action and the REST API (Professional and above) start scans from your pipeline and can fail the build below a score you set; the GitHub App checks every pull request preview.

How is this different from a linter like eslint-plugin-jsx-a11y?

A linter checks your source code; ADAGuard checks the rendered page — styles, scripts and third-party components included. They catch different things, and using both is good practice.

Can ADAGuard scan pages behind a login?

Yes, on Professional and above. You log in yourself in a secure remote browser and we never see your password.
