Free Cookie Scanner
Run a fast cookie scan on any website to review first-party cookies, spot possible tracking behavior, and understand which cookies may require closer privacy review.
Why Use a Cookie Scanner?
A cookie scanner gives you a fast way to see what a website is storing in a visitor's browser and why it matters. For developers, it is a practical release check after analytics, consent-banner, or tag-manager changes. For privacy and compliance teams, it helps answer a more important question: is the site setting only routine operational cookies, or is it introducing tracking behavior that may need stronger consent controls?
This free cookie checker focuses on cookies visible in the initial server response. That makes it useful for quick audits, first-pass reviews, and identifying obvious marketing or analytics patterns. You can review cookie names, domain scope, duration, and whether the cookie looks more like a standard session mechanism or a tracking-oriented behavior that deserves closer scrutiny.
Cookie scans matter because not all cookies should be treated the same way. Essential session cookies support login, checkout, and security workflows. Analytics and marketing cookies can be legitimate too, but under GDPR and ePrivacy rules they often require explicit consent before they are set. If you want the background behind those distinctions, read our guide to cookie scanners.
This tool checks cookies from the server's initial HTTP response. JavaScript-injected cookies from analytics, ad scripts, or tag managers require a full browser-level scan via the complete SitePrivacyScore audit.
How to Read These Results
Essential or session cookies are usually tied to logins, carts, fraud controls, or other core website features. They still deserve review, but they are generally easier to justify.
Analytics or marketing cookies need closer attention. If they support measurement, advertising, personalization, or retargeting, they may require explicit consent before they are set.
Long-lived cookies are worth a second look. A cookie that lasts for months or years creates a larger tracking footprint than a short-lived session cookie.
What This Tool Checks
- Cookie names and domains visible in the initial response
- Basic duration and persistence signals
- Lightweight classification into standard versus tracking-oriented behavior
- Whether the site appears to set cookies that may need closer consent review
For runtime tracker behavior, consent timing, and JavaScript-injected cookies, follow this check with a full privacy audit.
