IMHO XMPP / Jabber is the best Instant Messenger (IM) protocol (feddit.dk)

It is battle tested, standardized, widely used, have open source servers and apps, end-to-end encryption (OMEMO), self-hostable and are low on ressources and federated / decentralized.

I use it with family and friends. Conversations and blabber.im on android and Gajim on Linux. There's also apps for windows and Apple.

Curious if anyone here use it and why, why not?

EDIT: Doh. In these Lemmy times I forgot federated. Added.

I like XMPP and OTR is nice, but we need double-ratchet for secure communications and sync with multiple devices.

Omemo is double ratchet and my messages sync to multiple devices. New device can't read old messages sent before exchanging keys with the other clients.
