OpenCms from Alkacon Software is a professional, easy to use website content management system. OpenCms helps content managers worldwide to create and maintain beautiful websites fast and efficiently.

The fully browser based user interface features configurable editors for structured content with well defined fields.

OpenCms is based on Java and XML technology. It can be deployed in an open source environment (e.g. Linux, Apache, Tomcat, MySQL) as well as on commercial components (e.g.  Windows NT, IIS, BEA Weblogic, Oracle).

As true open source software, OpenCms is free of licensing costs.
