On my own hardware: At home I have a Raspberry Pi 4 running JellyFin as a local media server, also experimenting with PiHole. One of these days I'd like to pull my NextCloud server in-house.
VPS: Nextcloud (including calendar, notes, contacts & RSS/Atom), GoToSocial, WordPress, Gemini, and personal website with a mix of home-grown parts and sections managed through Eleventy.
I've also experimented with self-hosting Calckey , Snac2 and Mastodon, but Mastodon's too heavy for a single user and Snac2 is lighter than I want to go with for now. I may try Calckey again at some point, though.
Eventually I'd like to set up Wallabag and migrate from Pocket.
