KMuddy is a MUD client powered by KDE. It is the most powerful, fast, feature-rich and easy to use MUD client.

It offers many features such as powerful external scripting (which supports very many languages such as Python, Perl, Lua, C/C++), and it's own internal scripting. KMuddy has split-screen scrolling, command history, buttons, gauges, logging (both in plain text and HTML), multiple connections, regex support (on both aliases and triggers).
