Free Website Accessibility Scanner for WCAG 2.2 Checks

Scan a public webpage for automatically detectable accessibility issues. Review browser-based findings online and download a PDF with the observed results.

WCAG 2.2 A/AA-oriented checks Browser-based scan Downloadable PDF No card or account required

This is an automated single-page scan. Automated testing can identify many technical accessibility issues, but it cannot determine complete WCAG conformance or ADA compliance. Human review is required for a complete accessibility assessment.

What the free accessibility scan checks

Auditzo evaluates supported machine-detectable accessibility rules and browser-observed signals on the public page you submit. Findings are mapped to technical accessibility concerns without treating an automated result as a legal or conformance conclusion.

Structure, labels & ARIA

Detectable issues involving accessible names, roles, relationships, landmarks, headings, labels, ARIA usage and document structure.

Keyboard & focus signals

Automated browser signals related to keyboard reachability and visible focus behavior where those conditions can be detected reliably.

Reflow & responsive signals

Selected checks for 320px reflow and responsive behavior that can identify accessibility review candidates on smaller viewports.

Target-size geometry

Selected WCAG 2.2 target-size geometry signals for interactive controls where browser measurements can be evaluated automatically.

Know the limits of automation

A free WCAG scanner is a starting point, not a complete accessibility audit

Automated tools are useful for fast, repeatable detection. They cannot fully judge meaning, usability, real interaction quality or every assistive-technology experience.

Read: Accessibility Scanner vs Manual Audit

Automation can detect

Supported code, structure, relationship, geometry and browser-observable accessibility signals.

Human review is still needed

Keyboard journeys, interaction quality, meaningful alternatives, screen-reader behavior, context and user-impact assessment.

Some checks can be inconclusive

When automation cannot safely determine an outcome, the result should be reviewed rather than forced into pass or fail.

A clean scan is not certification

No automated issue detected means only that the supported automated checks did not find an issue in that page state.

How it works

From webpage URL to accessibility findings

Use the free scanner for a quick first look, then move to human verification when the findings matter.

01

Enter a public webpage

Submit one public http or https URL that you want Auditzo to inspect.

02

Run automated WCAG checks

The browser-based scanner evaluates supported WCAG 2.2 A/AA-oriented rules and technical signals.

03

Review findings & PDF

Review the observed results online, understand the limitations, and download the automated report when available.

Included free

Useful accessibility findings without a paid automated tier

Auditzo's automated accessibility scan is designed as a free first step. Use it to identify detectable issues, understand where manual review may be needed, and decide whether to investigate further.

When the findings matter

Move from automated detection to human-verified accessibility evidence

For important customer journeys, remediation projects, stakeholder review or legal/compliance review, Auditzo can manually evaluate representative pages and interactions, verify findings in context, document supporting evidence, and provide remediation-oriented guidance.

You can also view a sample accessibility evidence report before requesting a manual audit.

After the scan

Find it. Verify it. Fix it. Retest it.

Auditzo can support the next step when automated findings need deeper verification or remediation.

Human verification

Review representative pages and interactions to confirm accessibility barriers that automation alone cannot fully determine.

Remediation support

Turn confirmed findings into prioritized, developer-ready remediation guidance for internal teams, agencies or vendors.

Explore Remediation Support

Evidence & retesting

Document findings with context and evidence, then re-check selected issues after fixes are deployed.

From scanner candidates to evidence-backed findings

Auditzo's manual accessibility work adds page and component context, supporting evidence, remediation ownership and retest guidance when a basic automated scan is not enough.

FAQ

Website accessibility scanner questions

Is the Auditzo website accessibility scanner free?

Yes. The automated accessibility scan is free to run and does not require a paid account or credit card. Usage limits may apply to prevent abuse.

Does this scan prove WCAG or ADA compliance?

No. It provides automated technical observations only. Automated tools cannot evaluate every accessibility requirement or determine complete WCAG conformance or ADA compliance. Human review and context are required for a complete accessibility assessment.

What version of WCAG does the scanner check?

The current automated scanner evaluates supported WCAG 2.2 Level A and AA-oriented technical checks and browser signals. It does not automatically test every WCAG success criterion.

Does the free scan check my entire website?

No. The free scanner evaluates the public webpage URL submitted for that scan. A broader website accessibility audit should use a representative page and user-journey scope rather than treating one page as the entire site.

Why can automated accessibility testing miss problems?

Many accessibility requirements depend on context, meaning, keyboard interaction, focus behavior, dynamic states, assistive-technology behavior and real user journeys. These cannot always be judged reliably by automation.

Will Auditzo change anything on my website?

No. The automated scanner observes the public webpage through a browser and does not modify your website.

Can Auditzo manually verify the accessibility findings?

Yes. Auditzo offers human-reviewed WCAG-oriented accessibility audits for teams that need verified findings, supporting evidence, remediation guidance and retest planning.

What should I do after the scan?

Use the automated findings as a first-pass signal. If the page supports important user journeys, the findings are being used for remediation, or your team needs stronger evidence, move to a human-verified accessibility review before treating the scan as a complete assessment.

Start with a free scan. Move to human verification when the findings matter.
