Pidgin 1 vote

The universal chat client

Pidgin is a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time.

Pidgin runs on Windows, Linux, and other UNIX operating systems.

Pidgin is compatible with the following chat networks out of the box: AIM, ICQ, Google Talk, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, MXit, MySpaceIM, and Zephyr. It can support many more with plugins.

Pidgin supports many features of these chat networks, such as file transfers, away messages, buddy icons, custom smilies, and typing notifications. Numerous plugins also extend Pidgin's functionality above and beyond the standard features.

Pidgin integrates with the system tray on Windows, GNOME2, KDE 3, and KDE 4.

Pidgin is under constant development. Releases are usually frequent and driven by user contributions, such as bug reports and patches.

Pidgin is free and contains no ads. All our code is open source and licensed under the GNU General Public License. This means you can get Pidgin's underlying code and modify it to suit your needs, as long as you publish the changes you make for everyone to benefit from as well.
