Crawler that detects websites' compliance with Global Privacy Control signals.

Desktopfreeglobal

GPC Web Crawler is a free, open-source research tool that checks whether websites actually comply with Global Privacy Control (GPC) opt-out signals at scale, relevant to CCPA and do-not-sell compliance analysis. It's built for privacy researchers and compliance auditors who need to verify GPC compliance across many sites rather than checking each one manually.
