As everything, a big “it depends”. Each viewer will eat more bandwidth, but you control the compression and qualities. For me, I have an unlimited fiber uplink, so it’s quite easy for me to self host. If someone were more bandwidth constrained, then hosting it on a cloud that then has much more egress may help - at a cost of course, but then your own personal internet would only have the one outgoing stream. Finding a provider that has super cheap egress traffic would probably help
If you have a data cap… well… not a lot you can do.

This was an interesting question, so I took a quick dive in the docs, it seems it has an S3 integration to help with it, and some comments on the various supported services

Still, depending on the chosen provider and the amount of viewers, it could be quite costly
