I'm trying to see if I can host my own Fediverse instance for friends and family and I want to know what kind of device would be required. I'm an absolute beginner to self-hosting so I was wondering if I can start cheap (Raspberry Pi 2GB RAM is something I can definitely consider).

Also, can one device host multiple software? Like if I wanted both a WordPress instance and a Hubzilla instance or a Matrix/XMPP instance
