Microsoft ClaritySince 2023-01

Microsoft Clarity is a 100% free behavioral analytics tool built by Microsoft, widely used by US web developers, digital marketers, SaaS founders, and e-commerce store owners. It gives you a complete visual picture of how real visitors interact with your website — where they click, how far they scroll, and exactly where they lose interest and leave. Clarity's two core features are heatmaps and session recordings. Heatmaps show you aggregate click, scroll, and move patterns across your entire site in a color-coded visual. Session recordings let you replay individual user visits, including the ability to automatically flag frustration signals like rage clicks (rapid repeated clicking) and dead clicks (clicking on non-interactive elements). For US businesses managing CCPA compliance, Clarity is fully CCPA- and GDPR-compliant and automatically masks sensitive input fields — passwords, credit card numbers, and personal data — without any manual configuration.

What makes Microsoft Clarity exceptional for US users is that it has no usage limits whatsoever — unlimited sessions, unlimited recordings, unlimited heatmaps — all for free, forever. This makes it the most compelling free alternative to Hotjar (which charges $39–$99/month) and FullStory (which starts at $199/month) for US businesses watching their SaaS tool budget. In 2026, Clarity added an AI Copilot feature that generates natural language summaries of user behavior — instead of manually watching hours of session recordings, you can ask Clarity "Where are users getting confused on my checkout page?" and get an instant AI-generated answer. Clarity also integrates directly with Google Analytics 4, combining behavioral data (what users do) with traffic data (how they arrived) in a single dashboard.
