Clarity (Microsoft)
A free user behavior analytics tool that helps you understand how users interact with your website through session recordings and heatmaps.
Our take: Clarity is genuinely 100% free with no traffic caps, no paid tiers, and no credit card required — sustained by Microsoft using anonymized aggregate data for its AI and ad products.
The definitive free behavioral analytics tool — no serious website should skip it given the zero cost and zero traffic limits.

Our takeClarity is genuinely 100% free with no traffic caps, no paid tiers, and no credit card required — sustained by Microsoft using anonymized aggregate data for its AI and ad products.
Why we rate itClarity punches far above its price point (zero).
The catchMicrosoft's terms allow use of aggregated, anonymized behavioral data to improve its AI and advertising products — a fair trade-off many privacy-conscious teams will want to evaluate.
Best / not good for
- Teams that need session recordings and heatmaps with zero budget
- Sites wanting to complement Google Analytics with qualitative behavioral context
- Mobile app teams needing a free lightweight behavior SDK
- Teams needing on-site surveys, NPS, or user feedback collection
- Workflows that require A/B testing tied directly to session data
- Organizations with strict data-sharing policies that prohibit Microsoft's aggregated-data usage
Friction report
Trade-offs to know before signing up.
- Time to valueFast: paste a single JS snippet (or install a CMS plugin), and heatmap and recording data begins flowing within minutes.
- Scale breakpointNo hard traffic ceiling, but manual session review becomes unmanageable at high volume — the AI Copilot batch summaries partially mitigate this.
- Walled gardenLow: data exports are available and the Google Analytics integration lets you link sessions to GA segments; no vendor lock-in beyond the free dependency on Microsoft infrastructure.
