Cookie & Tracking Check

Why check cookies and tracking?

Many sites set third-party cookies and tracking scripts before you accept a banner. This cookie checker shows which resources and Set-Cookie headers the server sends on first load — so you see what is set before consent.

What we show

Cookies: every Set-Cookie header in the HTTP response (name, domain, path, Secure, HttpOnly, SameSite). Domain "(default)" means the cookie is scoped to the request host. Third-party resources: scripts, iframes, images, stylesheets, and other URLs loaded from the HTML that point to a different domain. The summary counts cookies and third-party domains; the table groups third-party resources by domain and type so you can see at a glance which external domains are involved.

Quick tips

• Look for domains that are not the site you visited — those are third-party and often used for tracking or ads.
• Cookies set in the HTTP response are visible here; JavaScript-set cookies are not, so the real picture can be larger.
• Use this for a privacy audit or to compare sites before choosing where to browse or buy.

Things to consider

We only see the initial response; JavaScript can add more cookies or trackers after load. Results are from our server’s request; your browser or location may get different third parties (e.g. geo-targeted ads).
