About X Frame Options Checker
X Frame Options Checker is used to verify whether a page sets the X-Frame-Options or Content-Security-Policy frame-ancestors header to prevent clickjacking attacks. It fetches the page headers and checks for X-Frame-Options (DENY or SAMEORIGIN) and equivalent CSP frame-ancestors directives. X-Frame-Options is being superseded by CSP frame-ancestors — set both for maximum browser compatibility. X Frame Options Checker runs free in your browser at abovetool.com — no signup required.
