Check a website

See what anyone can tell about a site from the outside: its headers and certificate, trackers it loads, mail settings, and public notices. Free. We read the site the way a visitor's browser does — we open only pages the site links to and send nothing.

We email the result to this address. The result on screen shows no software versions; to see those and the vulnerabilities for them, confirm you manage the domain afterwards.
