Free WCAG 2.2 Accessibility Checker & Chrome Extension
The Grammarly for Web Accessibility.
Stop spending hours decoding rigid, unorganized WCAG compliance reports. A11yEngine splits your webpage into logical components, explains business impact visually, and delivers instant, production-ready framework fixes.
✓ Official Chrome Extension • Free Install • 1-Click WCAG Audits
How A11yEngine Transforms Scanning
Leaves non-experts digging through complex compliance rules trying to figure out if it actually breaks user flow.
“The product card image communicates pricing information. Screen readers will completely miss this baseline value.”
How A11yEngine Operates
Eliminate manual compliance auditing and integrate real-time accessibility directly into your daily development routine.
Add to Browser
Install the extension on Chrome, Edge, Arc, or Brave in under 30 seconds with zero setup required.
Inspect Viewport
Open any local or production web page. The overlay engine scans DOM elements and maps issues in-context.
Copy 1-Click Patch
Review visual boundary highlights and copy framework-native code snippets (React, Vue, Tailwind) to fix errors.
Built for Agile Product Teams
A structured ecosystem that scales from initial localized prototyping directly into production continuous delivery pipelines.
85+ Automated Accessibility Coverage
Combines axe-core 4.10.0 with 43 custom heuristics to audit 85+ WCAG 2.2 Level A, AA, and AAA criteria across all web components.
Our Roadmap to Universal Design
How we’re rolling out advanced automation hooks to visual builders and design ecosystems.
Chrome Extension Live (v1.2.0)
Core visual overlay engine, component isolation, and on-demand local framework fix generation (React/Vue/HTML).
GitHub Action & CLI
Integrate A11yEngine into active repository commits to block non-compliant PRs before merges occur.
Figma Design System Sync
Map accessibility parameters inside design files to alert designers of contrast/heading flaws prior to handoff.
Supported Browsers & Ecosystems
Seamlessly integrates into your active development workflow without changing your stack or build setup.

Everything You Need to Know
Got questions about our browser companion, local privacy compliance, or framework compatibility?
The extension injects a lightweight, on-demand observer script into your browser viewport. It evaluates DOM elements section-by-section against WCAG 2.2 AA standards, drawing color-coded visual boundary boxes around accessibility violations in real time.
