Scan a Website for Cookies (Real Browser, Not a Header Peek)
ConsentProof is a cookie consent checker that scans any website with a real browser and records which cookies and third-party trackers fire before the visitor consents.
Why the browser has to be real
A tool that fetches HTML and reads response headers will miss nearly every cookie that matters, because analytics, session replay and advertising cookies are written by JavaScript after the document loads.
Running headless Chrome costs more per scan and takes longer, which is why free tools avoid it. It is also the only way to answer the question honestly.
What gets recorded
Cookies with name, host, first or third party, category and the millisecond they first appeared. Third-party requests with the host contacted and the vendor behind it. Local and session storage writes, which are increasingly used where cookies used to be.
All of it twice: once before any consent interaction, once after accepting.
Frequently asked
- How do I see what cookies a website sets?
- Open it in a private window with devtools on the Application tab, or paste the URL here and get the same list with vendors, categories and timings already resolved, for both the pre-consent and post-consent states.
- Can I scan a website I do not own?
- Yes. The scan does exactly what any visitor's browser does, from one page load. Please be sensible about volume; the rate limits are there partly for that reason.
- Does the scan include subdomains?
- It records every host contacted from the page you submit, including your own subdomains. It does not crawl to other pages on a free public scan.
