IPT is still running and easy to get into, Torrentleech is another, just as easy and almost a clone of IPT. Other than these, there is Milky which is new and open for now. These will suffice for most of your needs.

I see that you've mentioned "The Ego and the Id" by Freud. There is another work of his, five lectures on psychoanalysis from 1909 that i find very fascinating to read, https://dspace.mit.edu/bitstream/handle/1721.1/65347/sts-003-spring-2008/contents/readings/freud.pdf. Freud introduces the 'Talking Cure' and case studies that led to him developing what we commonly know as therapy.
Nextcloud AIO has an option to skip domain check. the github README hasinstructions. And i love nextcloud because it integrates many features in one, file sharing, office collaboration, chat, rss reader, mailbox, photos, calendar, address-book, etc.
I have two instances running, one public and one completely local. And having a domain is just convenient but not necessary.
