Getting CloudXR#

The NVIDIA CloudXR™ SDK consists of three main components, which are distributed separately:

  • CloudXR Runtime (Server): Download from NGC. An OpenXR-compliant runtime for Windows and Linux servers. Required for all deployments.

  • CloudXR Framework (Apple clients): Download from GitHub. A native Swift framework for building visionOS and iOS clients. Required for Apple Vision Pro, iPhone, and iPad support.

  • CloudXR.js (Early Access for Web clients): Download from NGC. A JavaScript framework for building web-based XR clients. Required for Meta Quest, Pico, and browser-based experiences. Currently in Early Access.

Additionally, there is a Stream Manager service that you can use to manage CloudXR Runtime instances, and many Sample Applications are available to help you get started.
