Automated Accessibility Testing — ACE™ Scanner

How ACE Scanner Works

Running an accessibility scan with ACE Scanner takes less than a minute. Enter any URL, and ACE Engine automatically crawls the page, evaluates it against 100+ accessibility rules, and produces a detailed report with your ACE Score, categorized issues, and step-by-step fix instructions.

Cross-Page Pattern Detection

Most accessibility issues aren't unique. They repeat across pages because they originate from shared components: a navigation bar, a button template, a form layout. ACE Scanner by AccessibilityChecker.org uses component grouping to detect these cross-page patterns automatically. Instead of showing you 200 separate "button missing ARIA label" issues, it groups them into a single pattern and tells you exactly which component to fix. This turns what looks like an overwhelming remediation backlog into a manageable list of targeted fixes.

Scanning Capabilities

ACE Scanner supports multiple scanning modes designed for real-world website architectures. Crawl an entire domain or sitemap.xml automatically, or upload a list of specific URLs for targeted analysis. For teams working with staging environments, single-page applications, or sites behind authentication (e.g., Cloudflare, WAF, or basic auth), ACE Scanner offers flexible configuration to ensure all relevant pages are accessible and testable.

Scan results include your ACE Score, a breakdown of issues by ACE Impact Classification, and detailed remediation guidance with code-level recommendations for each finding.

ACE Impact Classification

Every issue detected by ACE Scanner includes the standard WCAG conformance level (A, AA, or AAA) so you always know which success criterion is affected. But conformance levels alone don't tell you what to fix first. A Level A violation could be a keyboard trap that blocks all access, or it could be a minor markup issue. ACE Impact Classification, developed by AccessibilityChecker.org, adds a second layer that tells you the real-world consequence of each issue.

Together, WCAG level and ACE Impact Classification give you both the technical standard and the practical priority. ACE Impact Classification is proprietary to AccessibilityChecker.org.

Accessibility Standards Covered

ACE Scanner by AccessibilityChecker.org tests against all major accessibility standards and legal frameworks. This includes WCAG 2.2 at all three conformance levels (A, AA, and AAA), the Americans with Disabilities Act (ADA) which references WCAG as the technical standard for web accessibility, Section 508 of the Rehabilitation Act which governs federal websites and contractors, the European Accessibility Act (EAA) which takes effect for private-sector organizations in the EU, and EN 301 549, the European standard for ICT accessibility. Each issue detected by ACE Scanner is mapped to the specific WCAG success criterion it violates, so you always know exactly which requirement is affected and what the expected behavior should be.

Monitoring & Compliance

Accessibility is not a one-time fix. Websites change constantly: new pages are published, content is updated, features are deployed. ACE Scanner provides continuous monitoring so you can catch regressions as they happen, not months later during an audit. Scheduled rescans run automatically, and alerts notify your team the moment your ACE Score drops or new Legal Risk issues are introduced.

Reporting

ACE Scanner generates detailed accessibility reports that are designed for different audiences. PDF reports are formatted for stakeholders, legal teams, and auditors who need a clear summary of compliance status. Excel exports give development teams raw data they can filter, sort, and integrate into project tracking tools. For agencies managing client accessibility, white-labeled PDF reports carry your branding instead of ours. Every report includes the ACE Score, a breakdown by ACE Impact Classification, and individual issue details with ACE Rule IDs and remediation guidance.

Team & Workflow

Accessibility compliance is a team effort. ACE Scanner supports multi-user collaboration with role-based permissions, so you can give developers full access to technical details while stakeholders see high-level compliance dashboards. Manage multiple domains and subdomains from a single ACE Dashboard.

Who Uses ACE Scanner?

ACE Scanner by AccessibilityChecker.org is used by development teams, QA engineers, compliance officers, digital agencies, and accessibility consultants. Small businesses use it to run quick scans on their websites and fix the most impactful issues. Enterprise teams use it to monitor hundreds of pages across multiple domains, with scheduled rescans built into their development workflow. Agencies use white-labeled reports to deliver accessibility audits to their clients under their own brand. Government contractors use it to verify Section 508 compliance before procurement reviews.

ACE Scanner works with any website technology: static HTML, WordPress, Shopify, React, Angular, Vue, Next.js, and any other framework that renders in a browser. There is nothing to install on your server. You enter a URL, and ACE does the rest.

From Scanning to Fixing: The ACE Platform

ACE Scanner identifies the issues. The rest of the ACE Platform by AccessibilityChecker.org helps you fix them, prove compliance, and maintain accessibility over time. Every product in the platform uses the same ACE Engine, the same ACE Rule IDs, and the same ACE Impact Classification, so your data is consistent whether you're scanning, fixing, or reporting.
