The Code Project Open License (CPOL) is a software license published by The Code Project, a community site for software developers.
The license is mainly applied to content that is being published on the site.
The Code Project has a comparison of the CPOL to open-source licenses on their site.
The license is not "Open" as defined by the Open Source Initiative[5] because it places restrictions on how the software can be used, such as forbidding its use in illegal, immoral or improper material as well as a prohibition on commercial distribution of the code in isolation.
The CPOL is strictly for source code that is gratis, but is not recognized as a free or open license by the Free Software Foundation due to the restrictions within the CPOL forbidding usage for illegal purposes and the restrictions on selling the code without coupling it to a larger application.
