Analytics

PostHog Website Examples

PostHog is an open-source product analytics platform used by engineering and product teams who want full control over their user behavior data, session recordings, and feature flag management. Unlike SaaS-only analytics tools, PostHog can be self-hosted or deployed via PostHog Cloud, which means detection signals vary depending on how a given site has implemented it. AIWebsiteDetector's detection engine identifies PostHog installations using 3 distinct script patterns — typically referencing PostHog's CDN-served library or self-hosted JavaScript bundles — alongside 1 HTML pattern that appears in the page markup when the tracker is initialized. These signals are cross-referenced to produce a confident match whether the implementation points to PostHog's managed cloud infrastructure at posthog.com or a custom self-hosted endpoint. The dual deployment model — cloud versus self-hosted — makes PostHog one of the more technically interesting analytics platforms to detect reliably, as the script fingerprints must account for both standardized CDN paths and operator-customized configurations.
