Security header check

Paste a public URL. We run one request, read the response headers, and score them the same way we grade apps in the directory - quick signal, not a penetration test.

Check any public URL

We request the URL once and grade security headers - the same engine used on app listings. Not a full audit.

Paste example.com or a full URL—we will add https:// when needed. Public websites only; localhost and private networks cannot be scanned.
