Free Cookie Scanner

Why use a cookie scanner?

A cookie scanner helps you understand what a page is setting on the very first response and whether those cookies look disciplined from a security and governance perspective. That matters because cookie behavior touches security, privacy, performance, analytics, and compliance all at once. A page can appear tidy to a normal visitor while still setting too many cookies, exposing tracking identifiers without obvious consent controls, or missing basic hardening flags such as `Secure`, `HttpOnly`, and `SameSite`.

A strong scanner therefore needs to do more than list raw `Set-Cookie` headers. It should classify likely cookie roles, show which cookies are persistent or session-based, highlight missing security attributes, and look for banner or consent-manager signals in the HTML. That makes the result useful to marketers, developers, privacy teams, and technical SEOs instead of limiting it to a low-level header dump.

How to use this cookie scanner

Enter a public URL and scan the page. The tool fetches the initial response, parses the cookies returned in `Set-Cookie`, and then checks the HTML for signals that suggest a cookie banner or consent framework. Start with the governance score and the summary cards so you can see the broad shape of the setup quickly. Then look at category counts, because they help separate essential cookies from likely analytics or marketing identifiers.

After that, move into the warnings and recommendations. A site may set only a handful of cookies but still miss `Secure` or `HttpOnly` on important session values. A different site may set many tracking cookies and still show no obvious consent signal in the initial HTML. The best use of a scanner is not to chase a perfect score for its own sake. It is to spot where security, privacy, and governance deserve a closer review.

What the results can and cannot tell you

This scanner focuses on the initial response and the first page load. That makes it fast and useful, but it also means some client-side cookies may only appear after scripts run, after a user logs in, or after consent is accepted. So the scan should be treated as a strong first-pass audit rather than a complete behavioral simulation. Even with that limitation, the initial response is often enough to catch poor cookie hygiene, overuse of persistent identifiers, and obvious gaps in security flags or consent visibility.
