ProcessMaker OSS is not only cost-free, but is also freely available.  ProcessMaker OSS is licensed under the GNU Affero General Public License version 3.  This license ensures that all users have access to the source code, and can modify that source code so long as the resulting product also meets the licensing requirements.  For more information, see the GNU Affero General Public License version 3.

ProcessMaker OSS relies on the input and testing of an active community of developers and programmers to keep our product on the cutting edge.  For that reason, we release “early and often”.  ProcessMaker OSS is not as stable as our enterprise products, as it allows us to test new features and work out the kinks before releasing to our enterprise clients. We invite you to get involved with our ProcessMaker OSS open source project.  Get started by downloading the latest version.  Support for our open source community comes both from in-house developers and the community itself.  For documentation, user guides, FAQ, and much more, visit our community page.
