Clarity

Clarity is a free user behavior analytics tool from Microsoft that helps you understand how visitors interact with your website in detail. Its primary purpose is to provide visual, data-driven insights into user behavior so you can identify usability issues, optimize page layouts, and improve overall site performance. By combining session replays, heatmaps, and behavioral metrics, Clarity enables teams to make evidence-based design and product decisions.

Key features include session replays that show individual user journeys, clicks, scrolls, and interactions in real time-like playback, allowing you to diagnose friction points such as confusing navigation or broken elements. Heatmaps (click, scroll, and area maps) aggregate user interactions to reveal which sections attract attention and which are ignored. Clarity also offers automatic insights such as rage click detection, dead click identification, JavaScript error tracking, and excessive scrolling flags, helping you quickly spot UX problems at scale. It integrates with popular platforms like Google Analytics and supports high-traffic sites without sampling, ensuring you get a complete picture of user behavior.
