"Session Replay" is a feature of Sentry that records and replays all user interactions on web apps and websites, capturing user actions such as page visits, mouse movements, clicks, and scrolls, and network logs during those times. This allows developers to identify the exact point where an error occurs in their application, eliminating the need for manual steps to reproduce the issue. By using Session Replay, developers can easily solve issues without having to go through a plethora of manual steps, providing benefits such as easy issue reproduction, understanding the origin of reports, enhanced proactive support, fantastic user experience insights with Replay Details, and efficient debugging with network traces. It also eliminates the need for reporters to create screen recordings and attach them to project management software, reducing back-and-forth with reporters and improving overall user experience. By integrating Session Replay with other Sentry features, developers can gain a better understanding of their users' interactions and identify areas for improvement, ultimately resulting in a better UX for everyone.
