Using Session Replay to Find Bugs: Streamlining UX Debugging for Optimal Performance

Introduction

What Are UX Bugs and Why Do They Matter?

What exactly is a UX bug, and why should developers and testers care? UX bugs are technical glitches—think broken links, unresponsive buttons, or rendering errors—that disrupt user interactions on a website or mobile application.

These software bugs degrade user experience, frustrate visitors, and can lead to significant business losses. For instance, a 2022 study found that 60% of consumers abandon purchases due to poor website user experience, costing e-commerce companies billions (Storyblok, 2022). Similarly, slow load times drive away users, with 40% of shoppers abandoning websites that take longer than three seconds to load (Shopify, 2024). In e-commerce, technical issues like payment gateway errors contribute to checkout abandonment rates, which range from 60% to 80% (Hotjar, 2023, ContactPigeon, 2024).

These statistics highlight the urgency of identifying and resolving bugs to ensure seamless user experiences. UX bugs don’t just affect web apps; they’re equally critical in mobile applications, where mobile readiness and accessibility are paramount.
