Detailed information about the licensing of the different projects of bimserver.org can be found on our wiki. Downloading the source code of the BIMserver software is possible on Github.

The license is also available in the license.txt textfile in each subproject in the code repository. On this page some FAQs and additional information about the license usage and interpretation is given.

The license under which the bimserver.org software is released is a combination of Affero GPL, GPLv3 and/or LGPL from the GNU project. The different projects in our  repository are differently licensed. More info on that can be found on our wiki.

Use in commercial and/or closed source environments:
We get many questions about use of this software in a commercial environment. In short this software is perfectly usable in a commercial infrastructure. As a user you can use it in any project. Just using the software doesn’t force you to anything, only when you start distributing BIMserver and derived work you need to have a close look at the license.
Many developers think the GPL license holds them from using this software with closed/proprietary tools. This is not true. The BIMserver has a perfect open interface (API) to use. When your software tools interacts with BIMserver software through that API the license does not affect your work in any way. When you integrate BIMserver software with your own tool it is derivative work. A good way to check if you are interacting or integrating with BIMserver software is to run a BIMserver and your own tool on a separate machine, or a separate process. When you connect to BIMserver over the web with Internet Explorer this browser still is a closed tool from Microsoft; when you connect to BIMserver with your own developed tool the same goes: it is still your tool. When you are in doubt, its always smart to contact us (via license@bimserver.org). Our experience learns that some people that are scared about the license issues, don’t have to be because of our open API interface solution. We are happy to explain this to you.

Plugins, GUIs, and code snippets:
BIMserver is an open framework that uses Plugins. Derivatives of bimserver.org code inherit the Affero GPL code. Plugins build from scratch can also be licensed under the GPL license (and used as plugin in BIMserver).  This does not go for snippets, GUIs and some separate (or remote) running services where BIMserver is a client to that service. Again: when in doubt, feel free to contact us.
