Accessibility Checker: WCAG 2.2 & BFSG

Audits web pages for accessibility barriers with axe-core in a real Chromium browser and returns a clear, scored report per page. Reports are available in German (default) or English.

Since 28 June 2025 the German Barrierefreiheitsstärkungsgesetz (BFSG, the national law for the European Accessibility Act) applies to many consumer-facing online shops and services. First warning letters (Abmahnungen) have been reported. This Actor helps agencies, shops and developers find the issues an automated test can detect.

What you get per page

Features

• Rule sets: WCAG 2.0 A/AA, WCAG 2.1 AA (BFSG, EN 301 549) or WCAG 2.2 AA.
• Real browser rendering, so JavaScript sites are tested as users see them.
• Optional mini crawl: follow internal links up to 50 pages per site.
• Bulk lists of thousands of URLs.

Pricing

$0.01 per audited page. Pages that fail to load are not charged.

Limits

Automated tests typically find 30 to 50 % of all accessibility issues. Keyboard flows, screen reader wording and media alternatives need a manual review. This is not legal advice.

FAQ

What am I charged for? One event per audited page. Pages that fail to load come back as items with an error field and are not charged.

How many pages are checked? By default only the URL you enter. Set pagesPerSite (up to 50) to follow internal links on the same site, breadth first. maxPages (default 500, at most 5000) caps the whole run.

Does it test JavaScript sites? Yes. Each page is loaded in a real Chromium browser before axe-core runs, so content rendered by JavaScript is included.

Do I need a proxy or a login? No login is needed. Apify Proxy is optional and only helps with sites that block datacenter traffic.

Is the result legal advice? No. Automated tests typically find 30 to 50 % of all accessibility issues, and every item carries a disclaimer saying so.
