XChat was a popular Internet Relay Chat (IRC) client. It had a choice of a tabbed document interface or tree interface, support for multiple servers, and numerous configuration options. Both command line and graphical versions were available.

XChat was available for Unix-like systems and Microsoft Windows; derivatives with native support for OS X's Aqua interface were also available (see below). The official XChat software has been discontinued since 2012, with development moving largely to forks such as HexChat.[2][3]


XChat was a full-featured IRC client with a GUI surrounding the basic chat window. It included all basic functionality found in most other IRC clients, including nick completion,[4] connecting to multiple servers,[5] secure connections,[6] CTCP, DCC file transfers and chats, and a plugin system for various programming languages (including at least C or C++, Perl, Python, Tcl, Ruby,[7] Lua,[8] CLISP, D, and DMDScript[9]). Plugins allowed extending the features and customization of the functionality of XChat.

The default view for the client window was referred to as "tree view", but can be configured for a tabbed interface instead. Tabs changed color as text arrives, other users enter or leave channels, or another user addresses the user's nickname. The interface could display clickable operator ("op") commands and others, and allowed customization of fonts, event sounds, timestamps, and logging.[10] XChat implemented all standard IRC commands (e.g. /NICK or /JOIN), as well as DCC chatting (/CHAT), which allows chat to continue if the IRC server is disconnected.[10]

XChat ran on Unix-like operating systems and modern versions of Windows[11] Many GNU/Linux distributions include packages for XChat in their repositories, though most have now switched to the newer Hexchat.


The main body of XChat code was licensed under the GNU General Public License. However, on August 23, 2004, the official build for Windows had become shareware, and had to be purchased after a 30-day trial period. Previous builds for Windows were removed from the official site.[12] The authors stated that the shareware fee is required due to the excessive amount of time it took to make it compile under Windows.[13]

However, since the unix version of XChat's code is open source under the GPL, several free non-official builds for Windows were being maintained.[14]


XChat had been described as popular,[15][16] buildable for a variety of platforms. IRC Hacks: 100 Industrial-Strength Tips & Tools goes into depth explaining its setup, configuration, and advanced features under Unix[15] and OS X.[17]
