Accessibility Visualizer by Webability

Visualize and audit accessibility on any webpage. Inspect landmarks, headings, focus order, ARIA roles, and more.

Accessibility Visualizer by Webability Accessibility Visualizer is a powerful inspection and auditing tool for developers, QA engineers, designers, and accessibility professionals. It helps you see accessibility directly on the page by overlaying visual indicators that expose the underlying semantic structure and WCAG-related implementation — without modifying the site or affecting end users. Instead of guessing how assistive technologies interpret your UI, Accessibility Visualizer shows you exactly what’s there: landmarks, headings, focus order, ARIA roles, accessible names, alt text, form labels, and more — all in real time, right inside your browser. Built for structural accessibility, not surface-level compliance. ⸻ 🔍 Visualizer Features Toggle visual overlays to inspect accessibility structures on any webpage: • Landmarks – Highlights semantic regions (header, nav, main, footer, ARIA landmarks) • Headings – Displays heading hierarchy (H1–H6) and flags skipped levels • Focus Order – Shows keyboard tab order with numbered indicators • Accessible Names – Reveals how screen readers compute names (aria-label, labels, alt, text) • Images – Displays alt text and identifies decorative images • Links & Buttons – Shows accessible labels, roles, and destinations • Forms – Visualizes inputs, labels, and associations • Tables – Inspects headers, scope, captions, and structure • Lists – Reveals list semantics and nesting • Live Regions – Identifies ARIA live, alert, and status regions All highlights use non-intrusive outlines (no layout shifts) and update automatically as the DOM changes. ⸻ 🧪 Built-in WCAG Audit (axe-core) Run a one-click axe-core WCAG audit directly from the extension: • WCAG 2.0 & 2.1 (A / AA) checks • Issues grouped by rule and severity • Navigate through affected elements with on-page highlighting • View CSS selectors, HTML snippets, fix guidance, and WCAG references • Designed to support manual testing — not replace it ⸻ 🚫 What This Tool Is Not Accessibility Visualizer is not an accessibility overlay: • ❌ Does not alter or “fix” websites • ❌ Does not claim legal compliance • ❌ Does not replace manual or assistive technology testing • ❌ Does not inject user-facing UI It’s a developer and auditor tool, built for understanding and validation. ⸻ 👥 Who It’s For • Developers validating accessibility during build • QA teams checking acceptance criteria • Accessibility auditors reviewing structure and WCAG conformance • Designers verifying semantic intent • Students & educators learning accessibility in practice ⸻ 🔒 Privacy First • No data collection • No tracking • No analytics • No external servers Everything runs locally in your browser. ⸻ Developed by Webability Experts in structural accessibility, WCAG auditing, and inclusive web engineering.
