Real-Time Auditing in Your Viewport.
Meet the developer sidekick that flags WCAG errors visually as you code. Zero config required-simply install from the Chrome Web Store to segment layouts, verify keyboard focus routes, and inspect instant framework remediation patches.

Stop Guessing. Fix Accessibility Visually.
Legacy compliance checkers return long reports of nested HTML elements. A11yEngine behaves like a visual developer tool, computing real-time scores and mapping issues directly onto your active browser screen.
π― Visual Boundary Boxes
Highlights errors directly in your browser layout with color-coded severity boxes.
π Revenue-Path Highlighting
Prioritizes transactional pages (checkouts, forms) to fix high-risk errors first.
π Multi-Format Report Exporting
Generate self-contained, beautifully styled HTML audit reports for client delivery, or instantly copy structured Markdown summaries directly into your engineering tickets.
