Accessibility Checker: WCAG 2.2, EAA & ADA Audit (axe-core)

Check any number of web pages for accessibility problems with axe-core, the open-source engine used by most professional WCAG tools. For every page you get each violation with its impact, the WCAG success criterion (for example 1.4.3 contrast), the affected elements with CSS selector and HTML, and a plain how to fix text.

Since June 2025 the European Accessibility Act (EAA) applies to many online shops and services in the EU (in Germany the BFSG). This Actor gives you a fast first audit of your pages against WCAG 2.1 AA, the level the EAA's standard EN 301 549 uses.

• ✅ WCAG 2.0, 2.1 and 2.2, levels A, AA and AAA, plus optional best practices
• ✅ Real browser: pages are rendered with JavaScript, as visitors see them
• ✅ Ready to fix: selector and HTML of each affected element and the exact fix (for example the measured contrast ratio and the required one)
• ✅ Prioritized: issues sorted by impact (critical, serious, moderate, minor) and number of affected elements
• ✅ "Needs review" list for checks that need a human look
• ✅ Bulk: paste your sitemap URLs; pages run in parallel
• ✅ Fair billing: per checked page; pages that fail to load and pages excluded by robots.txt are free

passRate is the share of applicable rules the page passes, a quick health number for comparing pages (not an official WCAG score).

Pricing

A fixed price per checked page. In our test 3 pages took 26 seconds with the default 2 GB memory.

Paid Apify plans pay less: 10% off on Starter, 20% on Scale and 30% on Business and higher plans.

FAQ

Does a clean result mean my site is fully accessible? No automated tool can prove that. Automated checks find a large share of common issues (missing alt texts, contrast, labels, ARIA errors); keyboard use, screen reader flow and content quality still need a manual review. Use the "needs review" list as a starting point.

Is this legal advice for the EAA or BFSG? No. It is a technical check against WCAG rules that helps you find and fix problems.

Why is a page "blocked_by_robots"? By default robots.txt is respected. Turn it off only for your own sites or with the owner's permission.
