Plausible Analytics is a lightweight, open-source web analytics platform designed for privacy-conscious website owners, developers, and businesses seeking a compliant alternative to Google Analytics — operating without cookies and collecting no personally identifiable information. The AIWebsiteDetector.com detection engine identifies Plausible Analytics deployments through one distinct script pattern and one CDN domain, both of which serve as reliable fingerprints across self-hosted and cloud-hosted installations alike. These signals allow the detector to distinguish Plausible implementations with high confidence, whether the tracking script is loaded from Plausible's own CDN infrastructure or embedded as part of a custom self-hosted setup. Plausible is notably available both as a managed SaaS product via plausible.io and as a self-hosted open-source deployment, which means detection patterns must account for variations in script sourcing across different hosting configurations. This dual deployment model makes the CDN domain signal particularly valuable, as cloud-hosted sites consistently reference Plausible's external infrastructure, providing a stable and unambiguous detection anchor.
