Kadu – an open source Gadu-Gadu and Jabber/XMPP protocol Instant Messenger client for Linux, BSD and Windows.
Kadu is based on the Qt library providing support for various system platforms.
The program offers most of the basic functions of the original Gadu-Gadu program and many additional ones, such as:
– no ads
– support for many protocols
– assigning several networks to one contact (connected conversation history)
– dividing the list of contacts into groups
– sending text messages to all Polish mobile networks
– file transfer (DCC)
– conference calls
– sending and receiving images in the conversation window
– animated emoticons and support for sets for the original Gadu-Gadu
– encrypting connection using OpenSSL
– message encryption using OTR
– notification of events with sound, “balloons”, flashing of the Scroll Lock diode on the keyboard, execution of external commands
– flexible configuration of the program’s appearance, toolbars and advanced configuration of contacts
– advanced configuration of connection to the network (the ability to set the IP address and port of the server, setting the proxy server address)
The first version of Kadu was created in 2001 by Tomasz Jarzynka as a simple KDE API exercise. It started to be a non-official Gadu-Gadu client for Linux and other Unices (and Mac OS X) due to lack of an official client for these platforms.
