Free website accessibility scanner

Find accessibility issues. Then get a practical route to fix them.

ClearSite checks a live page for common WCAG-related problems, explains the findings in plain English, and tailors fix guidance to your platform. The first scan is free and needs no account.

Scan a web page freeNo signup. Most scans finish within a minute.

What you receive

A remediation queue, not a compliance badge.

Rendered-page checks

ClearSite runs axe-core against the page a browser renders, rather than judging the URL or source text alone.

Prioritised findings

Issues are grouped by severity so you can start with barriers most likely to affect important tasks.

Platform-aware guidance

WordPress, Shopify, Squarespace and Wix are detected automatically. Other sites receive HTML and CSS guidance.

A verification loop

Fix the source, scan again, and use the new result to check whether the detected issue has gone.

A useful first pass

What an automated accessibility scanner can and cannot check

W3C guidance is explicit that evaluation tools cannot determine every aspect of accessibility. Automated testing is valuable when it handles the checks machines can make reliably and leaves contextual decisions to people.

Common issues automation can flag

  • • Missing image alternatives
  • • Form controls without accessible labels
  • • Low text colour contrast
  • • Empty links and buttons
  • • Invalid or conflicting ARIA
  • • Missing page language and some structural issues

Questions that still need a person

  • • Whether alternative text is useful in context
  • • Whether reading and focus order make sense
  • • Whether complex keyboard journeys are usable
  • • Whether instructions and errors are understandable
  • • Whether captions and transcripts are accurate
  • • Whether the full customer journey works with assistive technology

For a definitive WCAG assessment or legal position, pair automated checks with manual testing by an accessibility specialist. ClearSite is a diagnostic and guidance tool, not legal advice or a compliance determination.

A five-step workflow

Turn one scan into a repeatable accessibility habit

  1. 01

    Start with a high-value page

    Scan the homepage, contact form, product page, booking flow or checkout before low-traffic content.

  2. 02

    Read the issue in context

    Use the affected element and plain-English explanation to understand the user barrier, not just the rule ID.

  3. 03

    Fix the shared source

    If the issue comes from a theme, template or component, repair it once where possible instead of patching each page.

  4. 04

    Re-scan after the change

    A successful code edit is not proof by itself. Run the page again and confirm the detected finding has cleared.

  5. 05

    Add manual review

    Test key journeys with a keyboard and assistive technology, and bring in specialist review where the decision needs human judgment.
