About HTTP Header Viewer
Lists the full response headers a URL sends back, each with a short note on what it does - caching, compression, the CDN that served it, the cookies it sets.
Underneath, the headers that protect visitors are checked against widely recommended settings: HSTS and its max-age, Content-Security-Policy (including whether 'unsafe-inline' has undone most of it), nosniff, clickjacking protection, Referrer-Policy and Permissions-Policy.
A missing header is not automatically a fault - an API has no use for clickjacking protection - so the notes explain rather than score.
How to use it
- 1Paste the URL
- 2Press Check - our server requests it and reads the headers
- 3Read the headers and the security audit, or copy them as text
