Site Behavior Lab
See what a site does, not just what it says.
Transparency index
What websites actually load: measured, not claimed.
The public library covers 98 successfully loaded sites from controlled visits. Each report records observable requests, cookies, and catalogued services from one visit—reproducible evidence, not a privacy score or verdict.
How coverage and category medians are counted
The committed library attempted 104 real sites. 6 sites only produced failed or block-page primary visits, and 2 successfully loaded sites had at least one request-capped recording that remains visible as lower-bound evidence. Category medians use 97 sites with an eligible, request-complete passive lead visit. Each site counts once, even when a comparison loaded both arms. Requests are also evaluated with the open-source adblock-rust engine and Brave’s default filter lists.

PageGraph imports require a .graphml file and its matching .meta.json sidecar. Unsupported evidence families remain censored rather than guessed.
