history
Brian Chan began developing Liferay in 2000 to enable non-profit organizations to use an enterprise portal solution. Liferay, Inc. was founded in 2004. The main office for Europe (Liferay GmbH) is located in Germany. The main branch for Asia has existed in Dalian, China, since 2007 .
At the end of 2008, the software was renamed Liferay Portal because Liferay Inc. brought out another product called Liferay Social Office . Liferay Social Office is a collaboration software that sees itself as an open source alternative to Microsoft Office SharePoint Server .
The number of software developers working on Liferay products is unknown. An indication of the approximate size of the developer community is the number of members of the official Liferay forum with around 35,000 members (as of 2019). Members of the Liferay developer community help each other with the development of their own portlets or with the integration of third-party applications. Liferay based on Glassfish was used for the WebSynergy portal and cooperation platform from Sun Microsystems . Sun has also developed some portlets for Liferay. According to the Liferay website, there are 80,000 prospects for Liferay Portal monthly.
In the Gartner report "Magic Quadrant for Horizontal Portal Products" in September 2010, Liferay Portal was named in the quadrant for leading solutions and is therefore the first and only open source alternative on par with the companies IBM (with Websphere Portal ), Microsoft ( with Microsoft Office SharePoint Server ), Oracle (with BEA WebLogic Portal ) and SAP (with SAP NetWeaver Portal ). Gartner defines the positioning of these companies in the leadership quadrant as follows: "The leaders in this Magic Quadrant have a full range of capabilities to support a variety of portal deployment scenarios, and have demonstrated consistent product delivery in meeting customer needs for a substantial period of time . Leaders have delivered significant product innovation over the course of their pursuit of portal customers, and have been successful in selling to new customers across industries. ". Since 2018 the former "Magic Quadrant for Horizontal Portals" has been called the "Magic Quadrant for Digital Experience Platforms (DXP)" by Gartner. In 2019, Liferay is positioned as a leader in this report for the ninth year in a row.
