The telegram app has a very nice interface, but I want to use a self hosted xmpp chat server.
Is there maybe a fork of telegram that makes it work with a self hosted xmpp server? I would imagine that this is possible.
If not, is there anything that at least gets close to how nice telegram UI is?
OP already clearly stated he want to use XMPP. What OP is asking is some client features the functionality of Telegram client. Or a fork of Telegram client, gutted out every signle line of code interact with the backend, replace them with a XMPP client library.
I think OP is quite clear that he wants something resembles to Telegram’s UI, but works with XMPP instead. The title is just part of the context. You still have to read the body, which uses terms “interface” and “UI”. This means he never intend something server side.
I won’t say your comment is inaccurate, but taken out of context and misinterpret what the OP means.
