Nothing. I don't have the time to maintain if I self host. So, I generally pay people to "self host" for me, like albyhub, nostr1.com, etc.

Not even pi-hole? No bitcoin node or ln node? Home Assistant?
No, I run Bitcoin core in my PC, but I am not sure that could as self host.
Well, it's technically selfhosted since you can communicate with the bitcoin network through your own node and not someone elses node but I agree, not the selfhosting I'm looking for. Pihole, btc node and CLN node has required extremely minimal maintenance. I log in and upgrade APT packages every now and then.
That said, it's good to know your limits on selfhosting. If you don't have time to maintain something, it's only going to be a bad experience.
