I want to selfhost a messaging service for my family. It should be secure and have voice calling option, ideally. Thank you.
Just for a family and friends I’d go for xmpp. Matrix is still an enormous greavy piece of software, hard to self host if you don’t want to pay for a gigantic server just for it. Also the UI is more like gamer/company chat (discord, slack…), what may not be what your family expect, coming from whatsapp, telegram, or plain sms. In the contrary xmpp is very light and nowadays a lot of tutorial exists on how to configure it, even with voice/video. Plus mobile apps like conversation match the habbits of other messengers.
This is outdated info. Matrix doesn’t need lots of resources these days. “for instance Synapse uses 5-10x less RAM than it used to (my personal federated server is only using 145MB of RAM atm!” - https://matrix.org/blog/2022/08/15/the-matrix-summer-special-2022/#making-it-fast
