looks great but seems like its primarily a server os ya?
Mm yes its for self hosting but its worth checking out to see if it fits what ur thinking. Im not a very technical person but the OS seems friendly to developers to adapt their apps to work within the OS...its got a nostr relay, tons of bitcoin and lightning functionality. Cant say much more than that, 👍
But it took me from a years ling bitcoin lurker to running my own node and lightning node over tor in about 2 days.
