[ О приложении ]

Kaidan is a simple, user-friendly Jabber/XMPP client providing a modern user-interface using Kirigami and QtQuick.
The back-end of Kaidan is entirely written in C++ using the qxmpp XMPP client library and Qt 5.

Kaidan is not finished yet, so don’t expect it working as well as a finished client will do.

For a list of supported XEPs, have a look at the Wiki.
