There is a hard limit of 32 users in a room, and those users can be made up of a mix of any supported device.
Pro users as well as free users have the same hard limit of 32 avatars.
Spatial supports a wide variety of devices with different computational needs so device will play a role in how many users can comfortably join. Room performance is influenced by the size and quantity of items in a given room. You may experience performance issues as the number of users and uploaded content increases.
If you wish to share the room to more users we recommend screen recording and streaming from a user in the web app to a service like Teams/Zoom.
If you have any questions regarding user limits please reach out to support@spatial.io
