  • Updated

This feature is only available as an add-on for Enterprise customers. Interested in learning more? Contact our Enterprise team today.

Enterprise customers can purchase per-space support for large-scale video streaming, which can support over 1000 viewers by casting from streaming software such as OBS or StreamYard.

Large-scale streaming is separate from Spatial’s regular screen share support, which supports only one Spatial instance at a time, and uses WebRTC for lower latency.

Scroll down to see how to set this up using OBS, Streamyard or Zoom in Spatial.

We recommend streaming from a computer with a stable high-speed internet connection.
