I am really struggling to replace facebook messenger / whatsapp for a few casual conversations. My friends and I are all wanting to move away. We are not heavy users of this but need it to work. I think the requirements are:
-
floss client for android, linux, windows
-
persistent history across devices
-
reasonable security
-
don't need to self host server
-
can send a message to offline user, they get it when they come online
-
not tied to or reliant on phone number / cell service
-
ETA: end user documentation explaining how to set up and common troubleshooting
tried:
-
matrix: the thing with having to keep track of room keys and stuff is too complicated. every time someone uses a new device it is a ton of issues and we could never quite get it ironed out
-
signal: tied to phone number, no history across devices
-
xmpp: similar to matrix the key situation is confusing, also no cross device history
-
ETA: simpleX: a lot of people here are mentioning simpleX. It didn't come up in previous investigations so will give it a shot.
- ETA 2: It doesn't seem to have persistent history across devices. Clarification?
I actually didn't think this would be such a problem but it is breaking us. we don't need a lot of sophisticated features like voice, video, moderation, 1000s of participants, spam protection etc that seem to be of concern to the projects. just simple text chat.
I wonder if Delta Chat would work for you.
I have seen it but never tried it. I kind of got the impression it was like a novelty/experimental thing rather than a general purpose serious application. Is that incorrect?
Does your email account get filled up with bazillions of messages? I once installed an app that "backed up" all my SMS to email; it made 1 email for every SMS. It was terribly annoying because when searching mail for something all these irrelevant scraps of old conversations ago clutter up.
Or do you just have a separate mail account to use on chat?
