Free cookie & tracker scanner
Enter a web address to see which cookies it sets and which third-party trackers it loads — first- vs third-party, and whether a consent banner appears. Free, and the URL is never stored.

Third-party trackers
The URL you enter is used only to run the scan. It is not stored or logged. This is a first check, not a full legal audit.
Cookies explained
First-party cookies
Set by the website you visit. Often used for essential things like keeping you logged in or remembering your cart.
Third-party cookies
Set by other domains loaded on the page (analytics, ads, social widgets). These usually need consent under EU rules.
Session vs persistent
Session cookies disappear when you close the browser; persistent cookies stay until they expire. Persistent tracking cookies deserve extra scrutiny.
Secure / HttpOnly / SameSite
Security attributes. Secure limits a cookie to HTTPS, HttpOnly hides it from JavaScript, and SameSite limits cross-site sending.
Cookies, the GDPR and ePrivacy — the basics
In the EU, the ePrivacy rules and the GDPR mean you generally need a visitor’s consent before you set non-essential cookies, such as analytics or advertising cookies. Strictly necessary cookies usually don’t need consent. A compliant setup typically means: a clear consent banner, no non-essential cookies before consent, an easy way to refuse, and a cookie/privacy notice that lists what you use.
This scanner helps you see what a site loads today. It is a starting point, not legal advice — check your specific obligations.
Frequently asked questions
What does this cookie scanner check?
It loads the page you enter and reports the cookies the server sets (first- or third-party, Secure, HttpOnly, SameSite, session or persistent) and known third-party trackers referenced in the page, plus whether a consent banner appears to be present.
Does it catch every cookie?
No. It sees cookies set by the server and trackers loaded in the initial HTML. Cookies set later by JavaScript, or only after you accept a banner, may not appear. Treat the result as a helpful first check, not a full audit.
Is it free, and is my input stored?
Yes, it’s free. The URL you enter is used only to run the scan and is not logged or stored.
Do I need a cookie banner?
Under the EU ePrivacy rules and the GDPR, you generally need consent before setting non-essential cookies (such as analytics or advertising). Essential cookies that are strictly necessary usually do not need consent. Check your specific situation.
