Scan any website for WCAG 2.1 compliance failures in minutes. Parallax automatically detects contrast issues, missing labels, keyboard navigation problems, and screen reader incompatibilities across your entire product surface.
The Web Content Accessibility Guidelines (WCAG) are the international standard for digital accessibility, and the technical basis for most ADA, Section 508, and EN 301 549 compliance requirements. Missing WCAG compliance exposes your organization to legal risk — and, more importantly, excludes a significant portion of your potential users.
Parallax scans your entire product against WCAG 2.1 Level A and AA criteria automatically. It crawls every page, evaluates the full DOM, and flags violations with the specific WCAG criterion number, the elements affected, the page count, and a concrete fix recommendation.
What manual accessibility reviews miss: Most manual reviews check a few representative pages. Parallax audits your full site — every product page, checkout flow, onboarding screen, and settings panel. Accessibility issues in low-traffic flows are still legal liabilities. Parallax finds them all.
The result is a prioritized list of actionable fixes, separated by violation (must fix) and warning (should fix), with estimated impact on affected user segments.
Scan for Accessibility Issues →The baseline. Violations here make content completely unusable for assistive technology users — missing alt text, keyboard traps, no text alternatives for media.
Required for most ADA and Section 508 compliance. Covers contrast ratios, resizable text, focus visibility, and consistent navigation. This is what most legal cases reference.
Best-in-class. Sign language interpretation, extended contrast ratios, pronunciation guides. Required for government services and public sector applications in many countries.
ARIA labels, landmark regions, heading hierarchy, and semantic HTML structure that screen readers depend on.
Tab order, focus traps, keyboard operability of all interactive elements, skip links, and logical navigation flow.
Text and UI component contrast ratios against WCAG 1.4.3 (AA) and 1.4.6 (AAA) thresholds across all page states.
Label associations, error identification, required field indicators, and input instructions for all form elements.
Alt text quality, decorative image handling, audio descriptions for video, and captions for media content.
Heading order, page titles, language attributes, table structure, and consistent navigation patterns across pages.
Parallax checks WCAG 2.1 Level AA, which is the technical standard most commonly cited in ADA lawsuits and Department of Justice guidance. We flag issues that are likely to create legal exposure, but we're a technical tool — not a legal opinion. If you're facing litigation, consult an attorney alongside running this check.
Browser extensions check a single page at a time. Parallax crawls your entire product — every page, every user flow — and gives you a unified report with severity rankings and cross-site patterns. It also evaluates interactive states that static page scanners miss.
Violations are confirmed WCAG failures where Parallax has high confidence there's a real problem. Warnings are cases where a criterion may be violated depending on context — they require human review. We separate these clearly so you can prioritize fixes.
The free tool works on publicly accessible URLs. Pro plan features include options for scanning authenticated or staging environments. Contact us for custom configurations.
After every significant code push is ideal. Accessibility regressions are common — a new component, a CSS change, a form update. The Pro plan supports scheduled re-audits so you catch regressions automatically.
1 in 4 adults in the US has a disability. Most accessibility issues are caught and fixed in minutes when you know where to look. Parallax shows you exactly where to look.
