Frequently Asked Questions
Everything you need to know about automated testing, WCAG 2.2 Level AA compliance, and remediation with Access Lens.
Access Lens is a free, high-performance web accessibility checker built to test websites against the international Web Content Accessibility Guidelines (WCAG 2.2 / 2.1 Level A & AA) and Section 508 / ADA standards.
It analyzes your live DOM structure, pixel-level color contrast ratios, semantic HTML landmarks, ARIA markup, keyboard focus indicators, and form controls. For every issue found, it provides the exact failing HTML element and developer-ready code fixes.
Yes, 100% free with no account or signup required. There are no paywalls, hidden limits, or credit card forms. You can test individual URLs or crawl entire multi-page websites instantly.
No automated tool can detect all accessibility barriers. Automated scanning typically catches between 30% to 57% of WCAG criteria, such as low-contrast text, missing image alternative text, broken ARIA attributes, and invalid heading hierarchies.
Crucial qualitative criteria—such as logical keyboard navigation flow, non-visual screen reader coherence, and dynamic focus management—require human inspection. That is why Access Lens also includes an interactive Manual Audit Checklist .
WCAG 2.2 is the current official W3C recommendation published in October 2023. It retains all WCAG 2.1 criteria while introducing 9 critical new success criteria designed to assist users with cognitive disabilities, low vision, and motor impairments on mobile touchscreens.
Key additions include Focus Appearance (minimum contrast and perimeter around focus rings), Focus Not Obscured (ensuring sticky headers or footers don't hide focused elements), Target Size Minimum (24×24px), and Redundant Entry. Read our in-depth Methodology & Standards guide .
Scoring 100% on automated scans is a vital milestone that eliminates the most common technical triggers for digital accessibility lawsuits under Title III of the Americans with Disabilities Act (ADA).
However, true legal compliance requires meeting all applicable WCAG 2.2 Level AA requirements, including those evaluated manually. We recommend conducting both automated crawls and regular manual assessments using our step-by-step checklist.
In Full-Site Crawl mode, enter your root domain. Access Lens automatically traverses internal links and currently audits up to a maximum of 10 pages per scan (with selectable presets for 5 or 10 pages).
We are actively working on expanding crawl capacity to support larger crawl sizes and full-site scanning in upcoming updates.
Before running the audit, you are presented with a review screen where you can add, remove, or refine specific URLs to ensure the scan covers the exact pages you need.
Every issue detected by Access Lens includes:
- Severity & Impact: Critical, Serious, Moderate, or Minor.
- Failing DOM Elements: Exact HTML tags and issue summaries.
- Actionable Code Fixes: Ready-to-copy HTML, CSS, or ARIA remediation snippets.
You can also consult our Web Accessibility Developer Handbook for comprehensive remediation patterns.
Once an audit completes, you can review findings across three tailored role views directly in your browser: Executive for high-level health scores, Project Manager for sprint roadmaps, and Developer for actionable code fixes.
One-click PDF export is currently in active development and is not published yet. We are working on delivering formatted, downloadable PDF compliance summaries in an upcoming release. In the meantime, you can easily share findings via the interactive role dashboards or use your browser's native print function to save the report.
