How works

  1. 1

    Enter a URL

    Type or paste any publicly accessible URL. The tool automatically adds https:// if no protocol is specified.

  2. 2

    Server fetches the headers

    Our server sends a HEAD request to the target URL, following up to 5 redirects and recording all headers at each hop.

  3. 3

    Headers are categorised

    Headers are sorted into Security, Cache & Performance, General, and Other groups. A security score is calculated based on how many recommended security headers are present.

  4. 4

    Review and fix

    Click any category tab to focus on specific headers. The security panel shows exactly which headers are present and which are missing, giving you a clear remediation checklist.

Header requests are made from our servers to the target URL on your behalf. The target URL is not stored or logged.
