Elefant is a full-featured, but refreshingly simple CMS and PHP Web framework. It features an intuitive, streamlined admin interface, a tightly integrated WYSIWYG editor, dynamically embeddable content objects for building dynamic Web sites without touching code, and an extremely fast, secure, and flexible framework for add-ons and themes. The core CMS includes page editing, a blogging engine, site navigation, file and user management, automatic version control, a tool for translators and multilingual site management, and an in-browser theme/layout editor. It is also extensively documented and has a small but friendly and active developer community.
Submin provides a Web-based admin interface to your Subversion and Git repositories. Its features include user/group management, path permission management, the ability to create svn repositories and managing commit email messages. For Subversion, authentication is done with htpasswd/svn authz, so it can use the same login information as apache2/svn (and trac). For Git, ssh is used, and the login information is synched whenever a change is made. The Web interface can also work with NGINX/uWSGI, but the Subversion part only works with Apache.
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 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.
