quassel

Qt 5 based distributed IRC client (client and monolithic binary)

Quassel IRC is a modern, cross-platform, distributed IRC client based on the Qt framework. Distributed means that one (or multiple) client(s) can attach to and detach from a central core that stays permanently online. Re-attaching your client will show your IRC session in the same state as you left it in (plus whatever happened while you were gone), and this even when you re-attach from a different location. An optional Beginner's Mode completely hides this feature, so Quassel IRC can be used like a traditional client.
