Please see the Feature List for an exhaustive list of OpenCms features. Have a look at the Guided Tour to see some screenshots of OpenCms in action.
OpenCms is true Open Source Software and thus there are absolutely no licensing costs for using the software. This, of course, includes commercial usage on as many servers or clients or databases as you like.
OpenCms is very stable and mature. The system has been in active Open Source development since 1999, and it has been deployed by a number of international companies and organizations large and small for websites as well as for Intranet or Extranet applications. Please check out the list of Reference Sites to get an impression of the sites successfully using OpenCms.
Certainly! OpenCms is supported by a number of interactive agencies and software consulting companies worldwide. Please see the Solution Providers section for a list of companies offering professional support for OpenCms worldwide.
If you decide to use OpenCms, you will benefit from the success of OpenCms as it gains more and more widespread use. Have a look at the Promoting and Sponsoring page to check how you can help us become OpenCms even more popular.
We welcome all development contributions to the OpenCms project, please check out our Development section for more details on how to participate in the OpenCms development. You can for example help by developing additions or enhancements to the OpenCms core system, by publishing OpenCms modules, by working on the documentation for OpenCms, or by translating OpenCms to other languages.
OpenCms uses the lesser GNU general public license, or LGPL, version 2.1. The LGPL is one of the most accepted Open Source licenses. It is verified as a "true" Open Source license by the Open Source Initiative (OSI). The full text of the LGPL is available on the website of the Free Software Foundation (FSF). For further information about the LGPL, please see the website of the FSF.
OpenCms has a build in module API (which is in fact a Java interface). All modules that use that API are in terms of the LGPL "works that use the library" and therefore are not bound by the LGPL license.
However, if additions or changes to the core system are made, the result is a derivative work, and certain restrictions apply, the most important being that the license used for the derivative work must also be the LGPL.
So companies can develop their additions to OpenCms as a module and choose any license they like. However, the OpenCms core system and all enhancements or additions to it will stay Open Source.
Since the OpenCms 5.0 release, the development of OpenCms is officially coordinated by Alkacon Software. An active Open Source community is participating in the OpenCms development and a number of solution providers around the world offer professional support for OpenCms.
The "OpenCms Group" was as group of individuals who where coordinating the OpenCms project initially when it was published as OpenCms source in the year 2000 up to the 5.0 release. Some people who have been members of the group left to pursue other careers or business ideas. Those who remained with the project founded Alkacon Software with the intention of providing the OpenCms community with a stronger background by completely focusing on OpenCms related development. Older parts of the OpenCms source code still have the name "OpenCms Group" attached because of copyright reasons.
The opencms.org domain was owned by someone else at the time we started the project, so we started with opencms.com as domain name. Later, we got in contact with the people who owned the domain opencms.org and they transferred the domain to Alkacon Software. Many thanks to Frank Staude from Trilos for that. So for the website, our official address is now opencms.org. The Java package names are still starting with com.opencms to ensure compatibility with older versions that were written before we acquired the opencms.org domain. Be assured that OpenCms is a real open source project, no matter what domain name we use.
OpenCms is based on ideas and software developed and deployed since 1994. The first versions of OpenCms were developed by Alexander Kandzior while working on various internet projects between 1994 and 1998.
The system showed great potential, but the the core business of the company Alexander Kandzior was working with at the time was to be a professional internet consultancy and not a software development company, so he decided to publish OpenCms as Open Source.
The first open source release of OpenCms was issued March 2000. Since then, OpenCms has been continuosly developed as an Open Source project. A number of companies and individuals have contributed to the development.
Starting 2002, Alkacon Software, a software development company started by Alexander Kandzior, has been doing most of the work on the core OpenCms system. Starting with the 5.0 release, Alkacon Software is also officially coordinating the further development of OpenCms and the opencms.org website.
