Microsoft Clarity: Pricing, Features & Alternatives

Clarity is the reason many small sites never pay for this category. Microsoft states it is "free forever", with no traffic limits, no sampling and no upgrade path to be pushed into. You get session recordings, click and scroll heatmaps, rage-click and dead-click detection, AI-generated session summaries, and a Google Analytics integration that links GA segments to recordings. The limits are about retention, not volume. Recordings are kept for 30 days, heatmaps for up to 9 months, and each heatmap is built from up to 100,000 page views. Team members per project are unlimited.
