Microsoft · Free heatmaps and session recordings with AI summaries
The best free heatmap tool, and the most widely used.
Microsoft Clarity says it serves 2M+ sites and apps globally, the biggest number on this list, and it is free forever with no limits on traffic. That is the main reason it is so widely installed: you can add it to a busy site without worrying about session caps. Its heatmaps show where people click, scroll and drop off, and you can compare them across page versions. Session recordings let you watch real visits, with Highlights pulling out the key moments of each journey. AI summaries give one-click takeaways, and an AI chat answers questions about your data. Clarity also covers mobile apps on Android, iOS, Flutter and React Native, says it is GDPR and CCPA ready, and now tracks when your content is cited in AI experiences. It fits small sites, bloggers and big teams alike that want solid behavior data before paying for anything.
