Kaidan is a simple, user-friendly and modern chat client. It uses the open communication protocol XMPP (Jabber).
The user interface makes use of Kirigami and QtQuick, while the back-end of Kaidan is entirely written in C++ using Qt and the Qt-based XMPP library QXmpp.
Kaidan does not have all basic features yet and has still some stability issues.
Key Features
- Audio messages – send audio messages for an easier and more personal conversation.
- Video messages – send short video messages to capture a moment and let your contacts experience it with you.
