What it does
Dual-Engine DOM Audit
Scans live rendered web pages for accessibility defects using open-source engines.
“The page is rendered in a headless browser, then analyzed in parallel by axe-core (Deque) and Pa11y.”
Multi-URL Batch Scanning
Audits multiple web pages at once to produce WCAG compliance reports.
“Queue up to 10 URLs and export a report for every page in the batch.”
RAM-Only PDF Auditing
Evaluates PDF documents against accessibility protocols while preserving data privacy.
“Websites are rendered in a real Chrome session before every rule runs; PDF files are parsed in memory and never written to disk.”
Jurisdiction Target Selector
Adapts report outputs to match regional digital accessibility laws.
“Pick from 9 supported jurisdictions; the report card and the exported PDF follow your choice.”
