Overview
Free accessibility scanner with screen reader simulation, tab order visualization, contrast checker, and deep structural analysis.
a11yProbe — Accessibility Scanner That Goes Beyond the Basics Most accessibility tools stop at surface-level checks — missing alt text, empty links, low contrast. a11yProbe goes deeper. It probes the structural architecture of your page to find the problems that other scanners miss. What makes a11yProbe different: ->Structural analysis — detects heading level skips, orphaned content outside landmarks, broken document outlines, and missing page regions ->Keyboard architecture audit — finds focus traps, unreachable interactive elements, broken tab sequences, and widgets with click handlers but no keyboard support ->ARIA deep validation — catches conflicting roles, orphaned references, invalid state values, and role/element mismatches ->Behavioral testing — simulates real keyboard interaction to catch focus traps and unexpected context changes that static analysis cannot detect ->Smart false-positive suppression — filters known false-positive patterns so you focus on real issues, not noise ->Cross-engine deduplication — runs multiple scanning engines and shows each issue once, not repeated across scanners Built-in tools: ->Screen reader simulator — experience your page the way JAWS/NVDA users do ->Tab order visualization — see the keyboard navigation sequence at a glance ->Contrast checker — hover any text for live contrast ratios ->Heading tree, landmark map, reading order, and focus issue overlays ->Behavioral test runner — automated keyboard and focus interaction tests ->PDF report generation with WCAG conformance mapping and legal compliance assessment Privacy first: All scanning runs entirely in your browser. No data is sent to any server. No analytics, no tracking, no account required. Open source under the MIT license.
