Check which cookies a website sets in the first response and review Secure, HttpOnly, SameSite, domain, path, and expiry attributes.
Free Website Cookie Checker
Cookies affect privacy, compliance, security, and analytics accuracy. This checker inspects Set-Cookie headers from the initial page response so you can see which cookies are created before JavaScript runs.
What the cookie checker audits
The tool reads Set-Cookie headers and highlights whether cookies use Secure, HttpOnly, SameSite, Path, Domain, Expires, and Max-Age attributes.
Privacy-first analytics angle
Swetrix is cookieless by design. If you are trying to reduce consent banners and privacy overhead, checking which tools set cookies is a practical first step.
Frequently Asked Questions
Does this tool detect JavaScript-created cookies?
It checks cookies sent in HTTP Set-Cookie headers from the initial response. Cookies created later by JavaScript may not appear in this report.
What does SameSite do?
SameSite controls whether a browser sends a cookie with cross-site requests. It helps reduce cross-site request forgery risk.
Why should cookies use Secure?
The Secure attribute tells browsers to send the cookie only over HTTPS, which helps protect it in transit.
Why does cookie usage matter for analytics?
Cookie-based analytics often require consent in privacy-focused regions. Cookieless analytics can reduce friction while still showing useful traffic insights.
Is a website with no Set-Cookie headers always cookieless?
Not necessarily. JavaScript can create cookies after the page loads, and embedded third-party resources can set cookies in their own contexts.
It's time to ditch Google Analytics.
Tired of the frustration, complexity and privacy issues of Google Analytics? We were too. That's why we built Swetrix - the ethical, open source and fully cookieless alternative.
