Microsoft Clarity vs Google Analytics 2026: Which Free Analytics Tool Wins?

Microsoft Clarity and Google Analytics 4 (GA4) answer fundamentally different questions — and you should use both together. GA4 tells you where traffic comes from, which channels drive conversions, and how users behave in aggregate. Clarity shows you what individual visitors actually do with session recordings, heatmaps, rage-click detection, and JavaScript error context. GA4 is free and irreplaceable for acquisition, conversion tracking, and Google Ads integration. Clarity is free and irreplaceable for session-level UX diagnosis. Setting up both takes under 15 minutes. The combination gives you a complete picture: GA4 identifies which pages have problems at scale; Clarity explains why at the session level.
