A11y X-Ray
Accessibility X-ray: landmarks, headings, missing alt/labels and tab order, in one click.
Description
A11y X-Ray gives you an instant accessibility X-ray of the rendered page (SPAs included), straight from the active tab: it maps ARIA landmarks (banner, navigation, main, contentinfo, complementary, form, search, region) with their accessible name, rebuilds the heading outline flagging level skips, missing or multiple h1 and empty headings, lists images without useful alt text (telling decorative ones apart), spots form controls with no accessible name (label, aria-label, aria-labelledby or title — placeholder alone doesn't count) and analyses the tab order, exposing positive tabindex values and reorderings that break keyboard navigation. An optional toggle highlights landmarks with labelled outlines overlaid on the page. 100% offline, zero telemetry, minimal permissions (activeTab on demand only).
Features
- ARIA landmark overlay (banner, navigation, main, contentinfo, complementary, form, search, region) with accessible name
- Heading outline rebuilt with warnings on level skips, missing or multiple h1 and empty headings
- List of images without useful alt text, distinguishing missing from explicitly decorative
- Form controls with no accessible name: error when absent, warning when only a placeholder is present
- Tab order analysis: positive tabindex (anti-pattern) and reorderings that break keyboard navigation
- Optional toggle that highlights landmarks right on the page with labelled outlines
- 100% offline, no data leaves the browser, minimal permissions (activeTab on demand)
