Muffinbot is a free IRC bot written in PHP and SQLite, and licensed under LGPL.

Our team has found the following true of other free IRC bots:  most are hard to install and configure for the average user, utilizing inconvenient configuration files; they have no capability of interaction through the Web or any non-IRC chat networks; and they have no capability for Web-based configuration and membership management.  Muffinbot aims (ha!) to change all that.

By contrast, Muffinbot will only require at least a simple setup script run from a command line with a small setup assistant. From there, all configuration, plugins, user management, and everything needed to keep the bot running is accessed through a sleek, secure web page. Part of the bot is stored online, including the scripts and images for the web portal; part is stored offline, including the configuration. Configuration is kept through an SQLite database.  It will respond to nearly anything you program it to respond to, alongside a fully-functioning web portal.

Future releases of Muffinbot are planned to contain the necessary drivers to store configuration in MySQL and PostregSQL, and to enable logging into MSN, AIM, Yahoo! Instant Messenger, and Jabber networks for user interaction there.
