Security Headers Checklist Builder
Build a security headers checklist from selected policies and copy a starter block.
What the Security Headers Checklist does
Build a security headers checklist from selected policies and copy a starter block. A small static site can collect HSTS, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy notes Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: Header values depend on hosting setup, so treat the output as a planning checklist.
Private and in your browser
Everything runs locally in your browser. Your input is never uploaded, so the tool stays fast and works offline, and the copy and download buttons always use the current result shown in the output panel.
