Multiple accessibility defect scanning engines

Not all scanning engines catch the same issues. Accessibility Cloud lets you test with multiple engines, including ACAI, our AI-powered engine, axe-core, and QualWeb. You can test your site with the same engine your country’s monitoring agency uses, so you can make meaningful comparisons and ensure nothing slips through.

Supported engines: ACAI, axe-core and QualWeb

User flow testing

Static page scans only tell half the story. Many accessibility issues surface only after user interactions, such as opening menus, filling out forms, selecting filters, or completing a checkout.

Accessibility Cloud can mimic real user interactions to uncover defects hidden behind membership flows, search, payments, shopping carts, booking systems, contact forms, and more. Visit your site, record your user flows, and let Accessibility Cloud test what other tools can’t.

Unlimited on-demand accessibility defect scanning

Scan your entire site whenever you want, with no limits, on all plans. Accessibility Cloud’s hyper-scalable infrastructure means you’re never waiting or rationing scans.

Expected scanning speeds:

  • 5,000 to 10,000 pages per hour for sites hosted in Scandinavia
  • 3,000 to 5,000 pages per hour for sites hosted elsewhere in Europe
  • 2,000 to 3,000 pages per hour for sites hosted anywhere else in the world
  • 10,000 to 100,000 pages per hour with an Accessibility Cloud on-prem scanner

Scanning performance depends on how fast Accessibility Cloud can communicate with your web server. Public scanners are primarily located in Scandinavia, with new scanners deployed to additional geographies as needed.

  • User flows: Authentication systems can be bypassed by creating a user flow for the login page.
  • Spoofing: Authentication tokens can be spoofed to bypass authentication systems
    • Cookies
    • HTTP headers
    • Local storage
    • Session storage
  • Whitelisting scanners: Whitelisting of IP addresses or user agents of of scanners.

Smart error grouping and prioritization

Accessibility Cloud doesn’t just list errors. It groups and prioritizes them across your entire site, highlights them visually on top of your pages, and automatically identifies what’s new and what’s been resolved between scans. Powerful filters let you slice results by error type, page, role, or guideline, and you can compare scans from two different dates to track progress over time.

Solution suggestions and learning

Every detected issue comes with solution suggestions, in-context learning material about the violated guideline, problem descriptions, and best practices. Accessibility Cloud also surfaces accessibility improvement suggestions that go beyond violations, helping you aim higher than baseline compliance.

Built to scale with your organization

Add as many websites, subdomains, viewports, and partial scans as you need. Accessibility Cloud doesn’t force everything into a single domain. Whether you manage one site or hundreds across different regions and configurations, the platform adapts to how you work, not the other way around.

Powerful exclusion controls

Fine-tune what gets scanned by excluding specific content, pages, URLs, HTML selectors, or all iframe tags across your site. This keeps your results focused on what matters.

Multiple compliance targets

You can choose multiple compliance targets for each site. You can also control the conformance level between AA and AAA and choose to include accessibility errors that don’t cause violations.

Currently supported: EN 301 549, WCAG, BITV, RGAA, Section 508 and ADA.
