Quassel IRC is a modern, cross-platform, distributed Internet Relay Chat (IRC) client based on the Qt5 framework.
It has the unique ability to split the graphical component (quasselclient) from the part that handles the IRC connection (quasselcore). This means that users can have a remote core permanently connected to one or more IRC networks and attach a client from wherever they are without moving around any information or settings.
Quassel IRC stores the backlog into an SQLite database. The database uses 64 bit message IDs and timestamps.
Features include:
- Establish simultaneous connections to multiple IRC servers.
- Nicknames, away reasons and the likes are managed via identities.
- Dockable nicklist and topic bar,
- Aliases.
- Chat monitor which displays discussions of a (configurable) selection of channels.
- Website preview for sites linked to in the conversation.
- Encrypt the connection between the quasselclient and the quasselcore with SSL.
- Proxy support.
- Query merging.
- Improved Desktop Environment integration.
- Editable shortcuts for all platforms.
- Shortcuts for navigation between chats.
- Emacs-style keybindings for the input line.
- Marker line can now be set manually (Ctrl+R), and one can jump directly to the marker line (Ctrl+K).
- Blowfish encryption (via /setkey and /delkey), also known as mircryption, FiSH or RFC 2045
- Full screen mode.
- Supports the modern Breeze iconset.
- On-demand creation of log files in custom formats from the backlog.
- Many IRCv3 features are now supported, including the rendering of almost all of modern formatting options.
- Authentication and configuration options allow for containerization, or for using an LDAP backend for the core
- Cross-platform support – runs under Linux, Mac OS X, and Windows. It should also run on any other platform that is supported by the Qt library. Third-party mobile clients for Android and iOS are available.
