XMPP protocol is almost abandonware. Basic specification is pretty poor, everything what you expect from messenger is a part of some extension. Not supported by particular server or not supported by particular client. Or built on extension still in "draft" past 15 years. Even the most used "pidgin" client is not supporting "must have" basic set of extensions.
Have you tried Conversations(Android) or Gajim(desktop)?
Tried Gajim 3y ago, put on "something is missing" list. Don't remember exactly.
There is a lot of jabber features not included in basic specification but via XEPs. Did not find a client that has all required XEPs implemented.
I cannot agree.
Just try Conversations on Android and Gajim on desktop.
xmpp is a solid and reliable protocol.
1. XMPP is solid. But without XEP is very limited. Client based on pure XMPP is almost unusable for people.
2. Tried to get list of supported XEPs for gajim. https://gajim.org/support/extensions is dead link - bad way to persuade me.
After spending some time of googling, I have got list of supported XEPs. Will give it a chance again.
Pidjin is old mate. See our video for newer ones that all all interconnected
Any multiplatform (Linux/Windows) jabber client not still in aloha phase on github? Seeking 3 years already.
(What video do you mean?)
