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 more.
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?
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.
