How the site works and what it is not.
Accuracy. Static analysis of pasted headers per RFC 9111; no URL is fetched. Real behavior also depends on method, status, and request headers.
Privacy. Everything runs in your browser; nothing is transmitted or logged.
Affiliate links. Some outbound links (e.g. CDN/hosting) may be affiliate links — we may earn a commission at no cost to you; it never affects the analysis. Ads may also appear.
