@shom I'm sure you could hack something together, but that's not Owncast is built to run, so it wouldn't be something you could do out of the box. You can absolutely host Owncast locally (I run an instance from my apartment), but it's public on the internet. A couple of people have mentioned a VPN or other type of tunnel, so maybe that's the answer. But honestly, I'm not sure, it's not really an Owncast-specific thing.
