Frequently asked questions
Does this prove WCAG conformance?
No. Automated testing detects only part of accessibility barriers. Conformance also requires expert review, keyboard testing, assistive technology and content judgment.
Does it crawl a public URL?
No. A Cloudflare Pages static page cannot safely bypass cross-origin restrictions. This tool audits pasted or local HTML in a controlled preview.
Why are some results marked needs review?
axe-core returns incomplete checks when human judgment or unavailable context is required. The checker keeps these separate from confirmed automated violations.
Which rules are available?
The presets cover axe-core WCAG 2.x/2.1/2.2 A and AA tags or best-practice checks. Exact rule coverage follows the bundled axe-core version.
