The SME Server server and gateway is free software (also referred to as open-source software) and is freely available for anyone to download.

This software is brought to you by the community and contribs.org. Many individuals and organizations (both commercial and non-profit) use the SME Server as their primary network server and gateway.

We would like to remind you that the SME Server software is licensed under the General Public License (GPL). This means that if you alter the software and distribute the altered version, you must make the source code for your altered version freely available.

The GPL is a large part of why free software has made such an impact on the commercial scene. By restricting anyone from making proprietary modifications, the GPL ensures that improvements find their way back to the original code base, thereby creating an explosive rate of technical advance.

The difference between traditional development and GPL development is the difference between a light bulb - where output is radiated in many directions - and a laser - where output is reflected back in a coherent way to produce a greater, more focused result.

Its main design focus is simple, centralized configuration, along with security and ease of installation.
