Server Driven UI (SDUI) allows mobile apps to receive UI definitions from servers instead of hardcoding them in the app, enabling instant updates without app store approvals. This approach eliminates deployment bottlenecks, enables real-time personalization and A/B testing, and gives teams the flexibility to iterate quickly. Companies like NuBank use SDUI for 70% of new screens, achieving instant updates and independent team deployments. Tools like Remote Flutter Widgets, Swap, and Stac make implementation accessible, though SDUI works best for flexible content areas rather than animation-heavy or offline-critical features.
