Ybot is erlang bot software inspired by Github hubot. It supports IRC and XMPP transports and is extensible with plugins. Plugins can be written with Python, Ruby, or shell. It supports IRC chat, XMPP multi user chat, and 37 signals Campfire chat. It can simultaneously run any number of bots on different transports.
Salut à Toi (or SàT: "Hi to You") is an XMPP/Jabber client with multi-frontends. You can use it on a desktop (Wix), with a console interface (Primitivus), as a command-line tool (jp), or on the Web (Libervia). A plugin architecture is used to make it modular. With SàT, you can perform all the expected XMPP functions (instant messaging, multi-user chat, file transfert, etc.), but you can also use your email client (MUA) to read and send your XMPP messages, play games, do microblogging, pipe Unix command results, make scripts, etc.
JSONBOT is a remote event-driven framework for building bots that talk JSON to each other over XMPP. This distribution provides bots built on the JSONBOT framework for console, IRC, XMPP for the shell and WWW, and XMPP for the Google App Engine. A plugin infrastructure can be used to write your own functionality.
GOZERBOT is a channel bot that aids conversation in IRC channels and Jabber conference rooms. It's mainly used to serve RSS feeds and to have custom commands made for the channel. More then just a channel bot, GOZERBOT aims to provide a platform for the user to program his own bot and make it into something useful. This is done with a plugin structure that makes it easy to program your own. There are over 100 plugins already written and ready for use.
Archipel is a solution to manage and supervise virtual machines. No matter if you have a few locally on your computer or thousands through data centers, Archipel is a central solution to manage them all. You can use all libvirt-supported virtualization engines like KVM, Xen, OpenVZ, or VMWare. You can perform all basic virtualization commands and many other things like live migration, VMCasts, packages, etc. Archipel uses XMPP for all communication. There is no Web service or custom protocol. You just need at least one XMPP server, like eJabberd, to start playing with it. This allows Archipel to work completely in real time. You never have to refresh the user interface. You'll be notified as soon as something happens. You can even use your favorite chat clients to command your infrastructure. You can open a chat conversation with your virtual machine and say things like "How are you today?" or "Hey, please reboot."
Poezio is a console-based client for XMPP, the protocol on which the Jabber IM network is built. Its goal is to let you connect to the network very easily (without having to create an account) and join various chatrooms immediately. It tries to look like the most famous IRC clients (such as weechat and irssi). Many commands are identical and you won't be lost if you already know these clients. Configuration can be done in a configuration file or directly from the client. It embodies the light, fast, geeky, and anonymous spirit of IRC while using a new, powerful, standard, and open protocol.
Ibid is a multi-protocol, general purpose, instant messaging chat bot written in Python. It aims for a naturalistic interface rather than strict-syntax commands. Ibid understands many protocols, including IRC, Jabber/XMPP/Google Talk, Campfire, NMDC, and SILC. It also interacts over SMTP, HTTP, and various RPC protocols. Ibid aims to make plugins as easy as possible to write. It ships with a large collection of plugins for looking up information, performing conversions, storing factoids, delivering messages, and much more.
