It is important to note that utilizing open source code may require substantial resources. For example, an organization that obtains open source software for free may have to hire software developers to modify and install the open source code. In some cases, there exists a community of software developers who contribute to a code base. In this case, there is more support for new software developers to begin using the code. In other cases (including with Dimagi’s open source products), a single company produces almost all the software, but the code is available for others to use.
You can find more detail about the CommCare code base on the Open Source section of the Dimagi website.
