Accessibility Checker: ADA, WCAG & Contrast – WCAGsafe

Free ADA & WCAG accessibility checker: score any page, find color-contrast failures & every violation. No sign-up, 100% private.

Check any web page for ADA and WCAG accessibility issues in seconds — right in your browser, with no account required and zero data sent to external servers. WCAGsafe runs the industry-standard axe-core testing engine — the same open-source engine trusted across the accessibility industry — directly against the web page you are viewing. In a single click, you receive an instant 0–100 accessibility score, a clear breakdown of issues carrying real ADA legal risk, and every WCAG violation complete with plain-English explanations and offending code snippets. It is free, private, and works on any http(s) page or local environment. ================================================== SCAN — Comprehensive On-Page Accessibility Audits ================================================== One-click automated scanning audits your active tab and delivers: • A 0–100 accessibility score, color-coded for instant visual feedback on page health. • A clear severity breakdown classifying issues into critical, serious, moderate, and minor categories. • An ADA legal-risk summary flagging the specific WCAG violations most frequently cited in web accessibility lawsuits. • Detailed violation reports featuring plain-English summaries, official WCAG criteria references (2.1 & 2.2 Level A/AA), and precise HTML/CSS code snippets to help you fix issues fast. ================================================== TOOLS — Visual On-Page Inspectors & Testing Utilities ================================================== Interactive testing tools drawn directly on top of your webpage: • Color Contrast Checker: Test any foreground and background color combination against WCAG AA and AAA ratios. Includes a one-click page scanner that locates every contrast failure on the page and suggests passing color alternatives. • Heading Structure Outline: Visualize H1 through H6 hierarchy trees to spot skipped levels, duplicate main headings, or missing document outlines. • ARIA Landmark Map: Clearly highlight banner, main, navigation, contentinfo, and complement regions across your layout. • Focus Order Visualizer: Draw the exact keyboard navigation tab path directly across interactive elements to catch tab traps and focus order defects. • Accessibility Overlay Detector: Automatically scan the page to detect whether a site relies on automated, third-party overlay widgets instead of native code-level compliance. ================================================== VISION — Real-Time Disability & Vision Simulators ================================================== Experience and test web pages through the eyes of different users: • Color Vision Deficiencies: Simulate Protanopia (red-blind), Deuteranopia (green-blind), and Tritanopia (blue-blind). • Visual Impairment Modes: Preview pages in full Grayscale, Low Vision / Blur, and Dyslexia reading simulations to identify readability barriers before publishing. ================================================== WHY WCAGSAFE IS DIFFERENT ================================================== Most browser checkers hand you a confusing list of raw code errors. WCAGsafe grades your page, prioritizes violations that pose the highest ADA litigation risk, and explains every issue in clear, actionable language. Developed by a dedicated accessibility team, WCAGsafe bridges the gap between technical web auditing and real-world compliance context. ================================================== WHO IT IS BUILT FOR ================================================== • Web Developers & Engineers: Catch accessibility bugs in local staging before pushing to production. • UI/UX Designers: Verify color contrast, heading logic, and visual hierarchy directly in browser prototypes. • QA & Compliance Teams: Audit client websites, document WCAG conformance, and generate actionable fix lists. • Business & E-Commerce Owners: Monitor store pages for ADA lawsuit risks and identify underlying accessibility issues. ================================================== PRIVACY FIRST — 100% LOCAL PROCESSING ================================================== Your data and privacy are fully protected. Every scan executes locally inside your browser using axe-core. We do not collect browsing history, record DOM elements, or transmit page data to external tracking servers. No account registration or sign-up is required to use any feature in the extension. When you are ready to expand your workflow — such as scanning multi-page websites, generating ADA audit certificates, or setting up automated monitoring alerts — visit https://wcagsafe.com. ================================================== SUPPORTED STANDARDS & COMPLIANCE SPECIFICATIONS ================================================== Built for web accessibility testing covering WCAG 2.1 & 2.2 Level A/AA, ADA Section 508, ARIA landmarks, screen reader prep, alt text verification, and color contrast ratios.
