what do you mean? You need a node at home (that's the tutorial for) or you pay for the hosted version (alby cloud). either way, you need a ln node (custodial by yourself or others)

just hadnt seen this setup before where you run the hub as a custodial lightning service, where you let the actual channel management to a lsp ☺️
only seen the umbrel/start9/raspiblitz bij custodial options.
but this is a very nice entry option to start without buying an expensive ssd and keep the costs low to try it out.
