Eggdrop is a popular IRC bot and the oldest that is still being maintained.[5][6][7]

Development History

It was originally written by Robey Pointer in December 1993 to help manage and protect the EFnet channel #gayteen; one Eggdrop bot version was named Valis.[8][9][10] Eggdrop was originally intended to help manage and protect channels from takeover attempts and other forms of IRC war.[7][11][12][13][14]


The bot is written in the C programming language and features interfaces for C modules and Tcl scripts that allow users to further enhance the functionality of the bot.[6][10][15]

A large number of Tcl scripts are available to expand the bot's functionality, most of them written by Eggdrop users.[6][16][17] Scripts are available to add and extend support for: online games, stats, user and channel management, information storage and lookup, greeting channel members, tracking last seen times, botnet management, anti-spam, file serving and distribution (usually via the DCC protocol), IRC services (similar to ChanServ and NickServ), and much more.

Eggdrop includes built-in support for sharing user information and channel bans. However, a script is required to simultaneously control multiple bots and for bots to coordinate channel management and modes.

The bot also features a "botnet", which allows multiple bots to be linked together to share data and act in a coordinated fashion.[10][13][15][18][19] The botnet supports a "party line", which is accessible via DCC CHAT and Telnet. People can communicate within the botnet on various channels in an equivalent to a miniature IRC. Channel 0, the default, is referred to as the "party line".[13][20]


Over the years Eggdrop has become one of the most popular bots run by IRC users.[13][21][22]
