1 in 6 people have a disability. WCAG compliance isn't just ethical — it's a legal requirement in many countries and it improves UX for everyone.
The legal reality
Web accessibility lawsuits grew 300% in the last 5 years. ADA, Section 508, and EAA (European Accessibility Act) all require WCAG 2.1 AA compliance.
What we check
- Image alt text — screen readers need descriptive text for every image
- Heading hierarchy — H1 present, logical nesting (no H1→H3 skips)
- HTML lang attribute — screen readers need this to pronounce text correctly
- Form input labels — every input has an associated label or aria-label
- Link text quality — no 'click here' or empty link text
- Skip navigation link — keyboard users need to skip past the nav
- ARIA landmarks — <nav>, <main> elements for page structure
- Viewport meta tag — mobile users need proper zoom support
- Color contrast — checking for low-contrast patterns in inline styles
What we can't check (yet)
Some accessibility issues require rendering the page and measuring pixels — like exact color contrast ratios, focus indicator visibility, and keyboard trap detection. These require browser-based testing tools like axe-core or Lighthouse. Our scanner catches the HTML-level issues that account for ~60% of accessibility failures.
