Tkabber is a GPL instant messaging client for the XMPP protocol which uses the Tk toolkit for the GUI. It runs on anything to which Tcl/Tk is ported: almost any X-based system (namely, any Linux and *BSD, Solaris, etc.), Microsoft Windows, and Mac OS X.



Tkabber was started by Alexey Shchepin (also the author of ejabberd XMPP server) in 2002. Several people contributed into it, notably Marshal T. Rose, Michail Litvak and Sergei Golovan, who is the current maintainer of the project.

In October 2004, Alexey Shchepin won an Honorable Mention for Tkabber in the ActiveState Programmer Network's Coolest Tk Screenshot Contest. Coincidentally, another Jabber/XMPP client was a Grand Prize Winner: Mats Bengtsson for Coccinella. [2]

The word "Tkabber" is built of two words: "Tk" and "Jabber" which alludes to the GUI toolkit used and the family of network protocols implemented. No one really knows how it is pronounced. Russian speakers (including the Tkabber's author, who invented this name) pronounce it as [t'kabber].


Tkabber is primarily distributed in the form of two tarballs containing the code of its "core" and standard external plugins. Since Tkabber is written in an interpreted language, it does not require any "building" for a target platform. Nevertheless, Tkabber is packaged by most of known Linux distros and FreeBSD. Also special "all-in-one" packages for Microsoft Windows are provided (they don't require separate installation of the Tcl/Tk runtime) in the forms of installer and starpack. Starpack for Linux x86 is also provided.

Mission statement

The goal of the Tkabber project is to create a cross-platform XMPP client which is feature-rich and is easy to hack. Tkabber is written in Tcl allowing it can be customized without knowledge of a low-level language such as C++ and its build system.

Pidgin (software) Open-source multi-platform instant messaging client

Pidgin is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log in to various services from a single application, with a single interface for both popular and obsolete protocols, thus avoiding the hassle of having to deal with a new software for each device and protocol.

XMPP Communications protocol for message-oriented middleware

Extensible Messaging and Presence Protocol is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML, it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses.

Kopete Free multiprotocol messenger

Kopete is a multi-protocol, free software instant messaging client released as part of the KDE Software Compilation. Although it can run in numerous environments, it was designed for and integrates with the KDE Plasma Workspaces. Kopete was started because ICQ blocked Licq from their network in 2001. According to the original author, Duncan Mac-Vicar Prett, the name comes from the Chilean Spanish word copete, meaning "a drink with your friends". Kopete has been nominated for multiple awards. The designated successor is KDE Telepathy from the KDE RTCC Initiative.

Off-the-Record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides forward secrecy and malleable encryption.

OMEMO is an extension to the Extensible Messaging and Presence Protocol (XMPP) for multi-client end-to-end encryption developed by Andreas Straub. According to Straub, OMEMO uses the Double Ratchet Algorithm "to provide multi-end to multi-end encryption, allowing messages to be synchronized securely across multiple clients, even if some of them are offline". The name "OMEMO" is a recursive acronym for "OMEMO Multi-End Message and Object Encryption". It is an open standard based on the Double Ratchet Algorithm and the Personal Eventing Protocol . OMEMO offers future and forward secrecy and deniability with message synchronization and offline delivery.
