Use copied headers only. This tool does not contact the header origin or read browser cookies.

Cookie guidance
Request header limits
A Cookie request header contains only name/value pairs, so response attributes must be reviewed from Set-Cookie lines.
Value handling
Values are hidden by default and can only be revealed per row. Report and JSON output stay redacted.
Scope review
Broad Domain, missing Path, and repeated names can change which cookie is sent or overwritten.
Attribute review
Secure, HttpOnly, SameSite, Partitioned, and prefix rules are checked as local parsing hints, not as a site-wide audit.
Official references
