I do host my own mastodon server with a small community, the initial setup is a bit complicated but once you get it going upgrades are nice and easy (each update contains all shell commands necessary outside `git fetch` and `git checkout v{VERSION}`)
Only downside of course is that if you selfhost alone, your federated timeline will be a bit empty, I do recommend either finding a community or starting one to get a bit more activity (Mastodon is essentially geared towards a sort of "community neighborhood" decentralization, where only one in a few hundred or thousand users needs to run a server, on average)
