How it works

Free HTTP header checker. Fetch a public URL, list the redirect chain, and grade HSTS, Content-Security-Policy, framing, nosniff, and Referrer-Policy. Private addresses are refused. The body is discarded.

  1. 01

    Enter a public URL

    A bare domain is treated as HTTPS. Local and private addresses are refused.

  2. 02

    Read the chain

    Each redirect shows the status and the location it pointed at.

  3. 03

    Read the grade

    The checklist names the header that passed, warned, or failed.
