Frequently asked questions
Is this a WCAG certificate?
No. It flags a few common mistakes with DOMParser heuristics. Real compliance needs manual keyboard testing, contrast checks and your legal counsel’s process.
Why paste instead of crawl my site?
Crawling production URLs from a third-party server would raise privacy and auth questions. Pasting a fragment keeps everything local.
Does it execute scripts in the snippet?
DOMParser builds a document tree; we do not eval inline script. Still avoid pasting untrusted secrets.
False positives?
Yes. Custom components may wire labels differently. Treat output as a triage list, not gospel.
