About Third Party Check

What it does

Third Party Check is a public scanner for seeing what a website loads before and after consent. It records third-party domains, cookies, and network requests on the initial page load, then accepts consent when a banner is detected and compares what changed.

Why it exists

The goal is simple: make consent behavior inspectable. Instead of reading policies or guessing from source code, you get a side-by-side view of the actual browser traffic.

Where the data goes

Aggregated request observations also feed Request Search, a separate public search interface for finding where scripts, pixels, SDKs, and endpoints appear across checked websites.
