Frequently Asked Questions
Can wcagkit replace WAVE for accessibility testing?
wcagkit covers many common checks (contrast, headings, alt text, ARIA, links) but does not offer WAVE's comprehensive single-page scan. For thorough audits, using both tools provides the best coverage.
Is WAVE free?
Yes. WAVE's web tool and browser extension are free. They also offer a paid API for automated testing at scale.
Which is better for beginners?
wcagkit's individual tools and WCAG reference with code examples make it more approachable for developers new to accessibility. WAVE's overlay can feel overwhelming when showing many issues at once.
Does wcagkit scan live websites?
wcagkit's tools work with code and content you provide. WAVE can scan live URLs directly. Both approaches have merit — wcagkit catches issues during development, WAVE validates deployed pages.
