The integrated set of software components, frameworks, libraries, runtime environments, and infrastructure services that together support the development and operation of a digital application or platform. In spatial computing contexts, a technology stack spans from hardware drivers and operating systems through XR runtimes, game engines, and application frameworks up to user-facing interfaces and cloud services.

Overview
A technology stack defines the complete layered assembly of technologies underpinning a platform. In XR and metaverse deployments, the stack typically spans operating system and device drivers, XR runtime (e.g. OpenXR), game or rendering engine, networking middleware, and cloud infrastructure, all integrating to deliver coherent immersive experiences.
