What we check
WCAG AA on every crawled page — not a homepage-only pass.
Contrast, keyboard, ARIA, labels, and headings across the pages we crawl.
Color contrast failures
Tests text against WCAG AA contrast ratios (4.5:1 normal, 3:1 large) on desktop and mobile.
Images missing alt text
Flags images without alt attributes where screen reader users need a description.
Keyboard & focus issues
Detects keyboard traps and pages where the focus indicator is missing.
Form labels & button text
Checks that every input has a label and every button has accessible text.
ARIA correctness
Surfaces invalid ARIA attributes, missing labels on interactive elements, and duplicate IDs.
Heading structure
Catches skipped heading levels, empty headings, and pages that lack an H1.
Links with no text
Identifies anchors with no visible or accessible text.
60+ axe-core rules
Runs axe-core on desktop and mobile viewports — not a homepage-only spot check.
