Secure Cookie Analyzer
Paste Set-Cookie headers and get a full security analysis of each attribute
Paste one or more Set-Cookie response headers and the analyzer checks each cookie for the attributes that protect sessions from theft and cross-site attacks: Secure, HttpOnly, SameSite, scope and lifetime. Each finding comes with a plain-language explanation and a recommended fix. More free security tools.
Paste one or more Set-Cookie header values (one per line). These are never sent anywhere — analysis runs entirely in your browser.
