Description
Making a website accessible — usable by people with visual, motor, or cognitive disabilities — is a legal requirement in many places (the WCAG standard) and, done well, makes a site better for everyone. The hard part is knowing exactly what's wrong and how to fix it in your specific codebase, not just that something is wrong. A11yEngine is a free browser extension built to close that gap.
A11yEngine is a Chrome extension for automated WCAG 2.2 accessibility auditing, built on the widely-used axe-core engine (version 4.10.0) plus 43 additional custom heuristics, marketed as 'the Grammarly for web accessibility.' It scans the page you're viewing in real time, visually highlighting violations directly on the DOM, and organizes findings by the WCAG POUR principles — Perceivable, Operable, Understandable, Robust — so you understand not just what's broken but which accessibility principle it violates. Distinctively, it suggests framework-aware code fixes for React, Vue, Next.js, and Tailwind CSS rather than generic advice, and bundles a 20-check technical SEO audit alongside the accessibility scan. All scanning happens locally in the browser, with personal data scrubbed before any processing, and the extension is free with no premium tier.
💬 Our review
The short version: if you build with React, Vue, or Next.js and want accessibility fixes suggested in the syntax you actually write, A11yEngine's framework-aware patches are a genuine step up from generic 'add an alt attribute' advice.
Its foundation, axe-core, is the same engine that powers Google Lighthouse and most other accessibility checkers, so the baseline detection quality is proven and industry-standard — the real differentiation is the 43 added heuristics, the POUR-principle organization for triaging issues, and especially the framework-specific code suggestions, which neither Lighthouse nor most raw axe-core extensions provide out of the box. The local-only processing is a legitimate privacy plus for anyone auditing internal or client sites they can't send to a third-party server. Being free with no paid tier is unusual for a tool this specific and suggests either a loss-leader strategy or limited scope ambitions — worth checking that it stays maintained as axe-core itself updates. Solid daily-driver for frontend developers who want actionable, framework-specific accessibility fixes; if you just need a pass/fail compliance score, Lighthouse alone may already be enough.
