psi-plus - Qt-based XMPP client (basic version)
is a capable XMPP client aimed at experienced users. Its design
goals are simplicity and stability. Psi IM is highly portable and runs on MS
Windows, GNU/Linux and macOS.
Psi IM is minimal but powerful. There are keybindings for just about everything,
Unicode is supported throughout and contacts are cached offline. Security is
also a major consideration, and Psi IM provides it for both client-to-server
(TLS) and client-to-client (GnuPG, OTR, OMEMO).
WebKit version of Psi IM has few additional features (in comparing with basic
version of Psi): support of animated emoticons, support of (adium) themes in
private chats and group chats, support of previewing of images and videos in
private chats and group chats, etc. But if you prefer old fashioned plain text
chats from era of IRC heyday, then basic version of Psi IM is your obvious
In 2009 a Psi IM fork named Psi+ was started. Project purposes are:
implementation of new features, writing of patches and plugins for
transferring them to upstream. As of 2017 all active Psi+ developers have
become official Psi IM developers, but Psi+ still has a number of unique
features. From developers point of view Psi+ is just a development branch of
Psi IM which is hosted at separate git repositories and for which rolling
release development model is used.
