| Pligg | |
| Originally named menéame in Spanish, is a web application that allows you to submit an article that will be reviewed by all and will be promoted, based on popularity, to the main page. When a user submits a news article it will be placed in the “unpublished” area until it gains sufficient votes to be promoted to the main page. The original source for Pligg was authored by Ricardo Galli. He was influenced by the extremely popular English technology site digg.com. | |

PHP-Nuke is a web based automated news publishing and content management system (a “nuke”[citation needed]) based on PHP and MySQL. The system is fully controlled using a web-based user interface. PHP-Nuke was originally a fork of the Thatware news portal system. |
| Mediawiki | |
| MediaWiki is a web-based wiki software application used by all projects of the Wikimedia Foundation, all wikis hosted by Wikia, and many other wikis, including some of the largest and most popular ones.[1] Originally developed to serve the needs of the free content Wikipedia encyclopedia, today it has also been deployed by companies as an internal knowledge management solution, and as a content management system. Notably, Novell uses it to operate several of its high traffic websites. | |
| Jboss Portal | |

Today’s top enterprises look to achieve a competitive advantage by deploying enterprise Portals within their IT infrastructure. JBoss Portal provides an open source platform for hosting and serving a portal’s Web interface, publishing and managing its content, and customizing its experience. While most packaged Portal frameworks help enterprises launch Portals more quickly, only JBoss Portal delivers the benefits of a zero-cost open source license combined with a flexible and scalable underlying platform. |
