Question 1

What is user experience monitoring software?

Accepted Answer

User experience monitoring software measures how real users perceive and interact with a digital product, tracking page load times, Core Web Vitals, JavaScript errors, and session behavior. It helps product and engineering teams detect and diagnose issues that hurt conversion, retention, or satisfaction.

Question 2

What's the difference between RUM and synthetic monitoring?

Accepted Answer

Real User Monitoring (RUM) passively collects data from actual users in production, giving you sample-of-one metrics across real devices, browsers, and geographies. Synthetic monitoring runs scripted transactions on a schedule from controlled locations, catching regressions before real users hit them but missing issues only certain segments encounter.

Question 3

How does session replay work and is it privacy-safe?

Accepted Answer

Session replay tools reconstruct the DOM at each interaction and render it as a video-like playback. Reputable vendors mask sensitive fields by default, support role-based access, and offer configurable retention. You'll still need to define what data your application sends—the tool can only mask what it sees in the DOM.
