Self hosting movement is hosting stuff yourself, so kinda, assuming you’re not putting some kind of advertising on your own services, but most commonly I’d see things like jellyfin, nextcloud, navidrome, immich and then a bunch of other stuff, there’s foss alternatives to most commercial offerings.
Awesome selfhosted
Is a great place to start.
