How Delivery Hero Accelerates UX Experiments with Server-Driven UI and Apollo

At the GraphQL Summit 2025, Delivery Hero highlighted how utilizing a two-layer Apollo supergraph architecture significantly enhanced their UX experimentation capabilities across various brands and markets. Initially, their attempt at a fully server-driven UI proved inefficient due to its complexity and slow adoption. The breakthrough came when they segregated business logic and UI presentation, allowing for faster configuration changes and reducing the need for lengthy release cycles. The adoption of Apollo GraphQL with Apollo Federation and Apollo Router facilitated a scalable and efficient platform, enabling real-time experimentation and rapid iteration. This architecture streamlined data requests from 80 fields to just four, improving performance and reducing design cycle times from three months to one week. The initiative not only improved technical efficiency but also strategically positioned Delivery Hero to compete in fast-paced markets by allowing product managers to experiment without waiting for new app releases.
