Find accessibility problems before your users do
Automated WCAG 2.1 audits check colour contrast, ARIA attributes, keyboard navigation and semantic structure — and tell you which criterion each violation breaks.

Accessibility is a legal requirement, not a nice-to-have
Accessibility rules apply to public sector bodies across the EU and to a growing set of private companies under the European Accessibility Act. Most teams only discover their gaps during an audit — or after a complaint. Automated checks catch a large share of common violations long before either happens.
How it works
Enter your URL
Point QA Proof at any public page. Nothing to install.
Pick a conformance level
Test against WCAG 2.1 Level A, AA or AAA depending on what you need to meet.
Work through violations
Each finding names the element, the WCAG criterion it breaks, and how to fix it.
What the audit covers
Eight compliance categories
Contrast, ARIA, forms, keyboard access, semantics, media, structure and navigation are checked separately.
Colour contrast analysis
Every text and background pair is measured against the ratio required at your chosen level.
Form label and ARIA validation
Catches inputs without labels, misused roles and ARIA attributes that reference missing elements.
Keyboard navigation checks
Flags focus traps, elements unreachable by tab, and missing visible focus styles.
WCAG criterion references
Each violation cites the specific success criterion, so an auditor can follow your work.
A, AA or AAA levels
Choose the conformance level you are held to instead of testing against a fixed standard.
Who uses it
Public sector suppliers
Meet the accessibility obligations attached to public contracts, with reports you can hand over.
Product teams
Fold accessibility into the regular release check instead of an annual scramble.
Agencies
Show clients a documented compliance position on every site you deliver.
