Hipergate is an open source web-based application suite. It is released under the hipergate Public License, which covers all open source requirements, and is very similar to GPLv3. It is a 100% pure Java, server-based application. That means you only need a web browser to access to all features. Any Servlet/JSP compatible web-server can handle it. Information is stored in a Relational Database. In 2.x releases, you can use PostgreSQL, Oracle, Microsoft SQL Server, MySQL 5 or IBM DB2.

Hipergate includes 7 different modules by default. Every module can be activated in a user/group/domain basis.
