Proof
Automated accessibility scans of any live page with Deque axe-core and Pa11y, with WCAG-tagged and best-practice findings kept distinct
Scan any public web page with two independent automated engines in headless Chrome: Deque axe-core and Pa11y (HTML CodeSniffer). Their measured findings blend into one automated accessibility score, with WCAG-tagged axe findings separated from axe best-practice findings and per-engine counts by severity. This is not a WCAG or ADA compliance audit or certificate.

Runs an automated accessibility scan of one public URL with two independent engines, Deque axe-core and Pa11y (HTML CodeSniffer), in headless Chrome. Blends their measured findings into one automated score, keeps axe-core WCAG-tagged violations separate from best-practice findings, and returns per-engine counts by severity plus the top findings with affected element counts. It is not a WCAG or ADA compliance audit or certificate. Usually done in 3-7 seconds.

Scope and boundaries for Web Accessibility Check.
Scan https://example.com in headless Chrome so axe-core and Pa11y independently evaluate the rendered public page.
Start with topViolations, addressing critical and serious rules with the largest affected-element counts before rerunning; use the blended score only as a progress indicator. No returned violations means these two automated engines found none in the rendered page, not that the page is WCAG- or ADA-compliant. axe.incomplete and all checks requiring human judgment remain unresolved.
This is an automated scan of one rendered page, not a WCAG or ADA compliance audit or certificate. Automated engines cannot cover every accessibility requirement or user journey; incomplete checks and issues involving judgment, assistive technology, interaction states, or content meaning still require manual review.
