See what a site does, not just what it says.

Run a controlled Chromium visit and read what the page actually loaded: request rows, cookie records, service-catalog matches and browser signals from that one visit.

One controlled visit.

GPC comparison is not available from this scanner.

Blocker comparison requires the Node scanner.

One controlled visit that records the requests, cookies, and scripts the page loads, up to a recording cap that is flagged when hit.

Privacy Signal

Global Privacy Control is a legal “do not sell or share my data” signal sent with every request.

Evidence, then interpretation

Reports disclose their scan conditions and exactly which evidence families were captured or unsupported. Recorded signals describe one visit, not a verdict about the site.

Transparency index

What websites actually load: measured, not claimed.

The public library covers 99 successfully loaded sites from controlled visits. Each report records request rows, cookie records, and service-catalog matches from one visit: reproducible evidence, not a privacy score or verdict.

median third-party tracking-service requests per site, by category
How coverage and category medians are counted

The committed library attempted 105 real sites. 6 sites only produced failed or block-page primary visits, and 5 successfully loaded sites had at least one request-capped recording that remains visible as lower-bound evidence. Category medians use 86 sites with an eligible, request-complete passive lead visit. Each site counts once, even when a comparison loaded both arms. Every one of them was measured under a single methodology cohort. Requests are also evaluated with the open-source adblock-rustengine and Brave’s default filter lists.

Open report files, PageGraph captures, or comparison tools

PageGraph imports require a .graphml file and its matching .meta.json sidecar. Browser imports are capped at 8 MB for report JSON, 16 MB for GraphML, and 256 KB for metadata. Unsupported evidence families remain censored rather than guessed.
