Microsoft Clarity is a free behavioral analytics platform developed by Microsoft, widely used by marketers, UX researchers, and web developers to visualize user interactions through heatmaps, session recordings, and engagement metrics. Detection of Microsoft Clarity relies primarily on two script patterns, most notably the presence of the `clarity.ms` CDN domain and the characteristic inline initialization snippet that calls `window.clarity` or loads from `https://www.clarity.ms/tag/`, both of which are injected into the page `<head>` as part of standard implementation. These script-based signals are highly consistent across deployments because Microsoft controls the delivery infrastructure, meaning the CDN domain and function signature rarely vary between sites — giving detectors a reliable, low-false-positive fingerprint. AIWebsiteDetector's engine leverages these two script patterns to identify Clarity deployments across a wide range of site categories, from e-commerce and SaaS landing pages to editorial and lead-generation sites. Because Clarity is offered entirely free of charge by Microsoft with no self-hosted option, every deployment routes through Microsoft's own CDN, making it one of the more straightforward analytics tools to detect with high confidence — there is no on-premise variant or custom domain proxying that would obscure the canonical signals.
