Jitsi (formerly SIP Communicator) is a free and open source multiplatformvoice (VoIP), videoconferencing and instant messaging application for Windows, Linux, Mac OS X and Android. It supports several popular instant-messaging and telephony protocols, including open recognised encryption protocols for chat (OTR) and voice/video/streaming and voice/video conferencing (///ZRTP), as well as built-in IPv6, NAT traversal and DNSSEC. Jitsi and its source code are released under the terms of the Apache Software Licence.

Work on Jitsi (then SIP Communicator) started in 2003 in the context of a student project by Emil Ivov at the University of Strasbourg. It was originally released as an example video phone in the JAIN-SIP stack and later spun off as a standalone project.

Originally the project was mostly used as an experimentation tool because of its support for IPv6. Through the years, as the project gathered members, it also added support for protocols other than .

Jitsi has received support from various institutions such as the NLnet Foundation, the University of Strasbourg and the Region of Alsace and it has also had multiple participations in the Google Summer of Code program.
