Psi was created in 2001 by Justin Karneges as an open‑source client for XMPP. Initial development used the C++ language with the Qt framework. Over the years, international teams contributed, including developers from Russia, Germany and the United States. The current stable version maintains compatibility with XMPP specifications RFC 6120‑6122 and community extensions. The project remains active with regular updates that fix bugs and add features.
