A11yEco — WCAG 2.2 accessibility analyzer with axe-core, contrast eyedropper, heading outline, focus order, and vision simulators.

A11yEco is a free, privacy-first WCAG 2.2 accessibility checker that audits any web page in seconds, right inside your browser. Built on axe-core, the same engine trusted by Microsoft, Google, and Deque, it turns "is this accessible?" into an answer any developer can act on. WHY DEVELOPERS CHOOSE A11YECO • Free -> no accounts, no paywalls, no data collection • Runs 100% locally -> your scans, pages, and content never leave your browser • One consistent engine across Chrome, CLI, and CI/CD pipelines WHAT YOU CAN DO 🔍 Full-Page & Component Scans Run a complete WCAG 2.2 A/AA/AAA audit of any page in one click, or right-click any element for a scoped component scan. Perfect for component libraries and design systems built with React, Vue, or Angular: audit a button, a modal, or a checkout form in isolation and get only its violations, its score, and its WCAG references. 📊 Accessibility Score Every scan produces a weighted 0 to 100 accessibility score, so you can track page health across releases and prove improvement over time. 🎨 Contrast Checker Eyedropper, manual color input, or a full-page contrast sweep, every result shows the exact ratio, the WCAG 1.4.3 threshold, and a pass/fail verdict. 👁 Vision Simulations Preview your site with 7 types of colour vision deficiency (protanopia, deuteranopia, tritanopia, achromatopsia, low-vision blur, cataract), live on the page, no reload required. ⌨️ Focus Order & Keyboard Audit Visualize the complete tab sequence with numbered overlays, spot traps and order gaps, and verify keyboard reachability (WCAG 2.4.3). 🌳 ARIA Tree Inspector Explore the live accessibility tree exactly as screen readers see it: computed roles, accessible names, states, and properties. 📑 Headings, Landmarks & More Heading hierarchy validation, landmark navigation with duplicate detection, reading-order overlays, text-spacing and reduced-motion testing, and an alt-text overlay for image-heavy pages. 📈 History, Trends & Dashboard Every scan is saved locally with per-URL trend charts, POUR health (Perceivable / Operable / Understandable / Robust), user-group impact analysis, and a priority queue that tells you exactly what to fix first. WHO IT'S FOR Web developers, accessibility specialists, QA engineers, and design-system teams who want WCAG 2.2 compliance built into their workflow, from design review to CI/CD.
