What standard we check against
PlainFix is built around WCAG — the Web Content Accessibility Guidelines from the W3C. Here is what that means without the jargon pile-on.
The exact name
WCAG means Web Content Accessibility Guidelines. Public sites commonly aim for WCAG 2.1 Level AA (or 2.2 AA). PlainFix runs axe-core checks tagged for WCAG 2.0 / 2.1 Level A and AA.
Levels A, AA, and AAA
Level A covers basic barriers. Level AA adds widely expected criteria such as contrast and consistent navigation patterns. Level AAA is stricter and not always realistic for every page. Most teams treat AA as the practical target for public content.
What automation can and cannot do
Automated engines like axe-core are strong at catching machine-detectable issues: missing alt text, unlabeled inputs, language attributes, many contrast failures, and certain ARIA mistakes. They cannot fully judge content quality, complex journeys, or every keyboard experience. A PlainFix report is a remediation starting point - not a certificate and not a claim that your site is legally compliant.
How PlainFix uses the standard
We open your URL, run the axe scan, then turn findings into plain-English explanations and concrete code-level fixes. Free scans show full severity counts and a few sample fixes. A full report unlocks every suggestion for that page.
