Liferay Portal is a free and open source enterprise portal written in Java and distributed under the GNU Lesser General Public License and proprietary licenses. It is primarily used to power corporate intranets and extranets.
Liferay Portal allows users to set up features common to websites. It is fundamentally constructed of functional units called portlets. Liferay is sometimes described as a content management framework or a web application framework. Liferay's support for plugins extends into multiple programming languages, including support for PHP and Ruby portlets.
Although Liferay offers a sophisticated programming interface for developers, no programming skills are required for basic website installation and administration.
Liferay Portal is Java-based and runs on any computing platform capable of running the Java Runtime Environment and an application server. Liferay is available bundled with a servlet container such as Apache Tomcat.
