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 wrote an XMPP-to-REST bridge, one-to-N. Everything gets its own rail and message queue on the bridge so as long as something can make HTTP requests, it can send messages and receive them. Huginn agents, any of my bots (written in Python), even shell scripts. Just about everything I have that crunches numbers has at least one of those bridges and a population of bots running on it.
There’s nothing wrong with command line chains, I have a really cut down version of System Bot re-implemented as a shell script (developed under Busybox’s default shell) for my OpenWRT stuff.
