As extended-reality (XR) hardware becomes more capable, web and interface design are gradually expanding into spatial environments. Industry discussions of UI/UX trends for 2025 highlight spatial interfaces, ambient computing and multi-device experiences as emerging themes, where digital content is layered onto physical spaces rather than confined to a rectangular display.
For web technology, this shift is supported by APIs such as WebXR and by performance improvements from WebAssembly and WebGPU, which can render complex 3D scenes and handle real-time interaction in the browser.
Designing for this future means thinking beyond pages and screens. Spatial interfaces must manage depth, ergonomics and attention: where a panel appears in the room, how far the user has to move their hands, and how information follows them across devices. Accessibility and comfort—such as motion-sickness reduction and clear focus cues—will be as important as aesthetics. Although mass adoption will take time, experimenting now with lightweight 3D patterns and device-agnostic layouts can prepare teams for a more immersive, post-screen web.
