Platform Overviews
PostHog
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.
Google Analytics
Google Analytics is a web analytics platform developed by Google, widely used by businesses, publishers, and developers of all sizes to track visitor behavior, measure traffic sources, and analyze site performance. AIWebsiteDetector.com identifies Google Analytics deployments through a combination of two distinct script patterns and two HTML patterns, typically including references to Google's analytics JavaScript libraries and associated tracking markup embedded in page source code. These signals are reliable indicators because Google Analytics implementations follow consistent structural conventions whether the tracking code is loaded via gtag.js, analytics.js, or through a tag manager integration. The platform is free to use at its standard tier, with Google Analytics 4 (GA4) representing the current generation following the deprecation of Universal Analytics, a transition that introduced new script signatures our detection engine accounts for. Detection confidence is high across virtually all site categories, as Google Analytics remains one of the most ubiquitous third-party scripts on the web, found on everything from small personal blogs to large enterprise properties.
