The mobile development landscape has long been divided by framework wars: Native vs React Native vs Flutter vs Progressive Web Apps. While traditional comparisons often rely on synthetic benchmarks or oversimplified examples, this talk presents a unique approach: leveraging multiple AI coding agents to build identical, real-world applications across different mobile frameworks, then evaluating the results through objective metrics. This session will demonstrate how various AI agents tackle the same mobile app requirements using Kotlin/Swift (Native), React Native, Flutter, and modern web frameworks. We'll dive deep into the challenges each agent encountered, the quality of code produced, and provide a multi-dimensional evaluation framework that goes beyond surface-level comparisons.
