A11yDetector

Extension to detect accessibility issues on web pages.

Most accessibility extensions only scan your DOM. They find missing alt tags and static contrast issues. That's useful — but it covers roughly 25% of WCAG. A11yDetector is different: it navigates your site with a keyboard, activates controls, and measures focus in dynamic states. It catches the issues that static scanners physically cannot detect. WHAT IT TESTS: ✓ Keyboard navigation (WCAG 2.1.1) ✓ Keyboard traps (WCAG 2.1.2) ✓ Focus order (WCAG 2.4.3) ✓ Focus visible indicators (WCAG 2.4.7) ✓ Color contrast — including :hover and :focus states (WCAG 1.4.3, 1.4.11) ✓ Zoom & reflow at 200% (WCAG 1.4.4, 1.4.10) ✓ Screen reader compatibility (WCAG 4.1.2) WHAT MAKES IT DIFFERENT: - The only extension that performs interaction-based testing - Auditor-grade reports: affected code, suggested fix, reproduction steps, user impact, and grouping of repeated occurrences - Export to Excel / HTML with one click - Configurable viewports (Desktop, Laptop, Tablet, Mobile, Custom) - Scan full pages or specific sections via CSS selector FREE: 5 scans/month. No credit card. PRO: Unlimited scans, exports, and history. From $29/month. Built by A11ySolutions — a team of certified accessibility specialists.
