OpenRules licensing policy is dual that makes OpenRules software available to both open source and commercial customers:

1. GPL Licenses for Open Source Projects.  If your application is available under the terms of GPL or a compatible open source license, you are free to use OpenRules without any license fee under the terms of GPLv2, the most popular Open Source license known as "GNU General Public License" (GPL).  Keep in mind, that GPL requires any "derivative works" to be also covered by GPL.  In particular, it means that source code of the applications that are based or use OpenRules should be made publicly available.

2. Non-GPL Licenses for Commercial Projects.  If you are developing, using, distributing, or providing services with non open source applications and these applications are based on or use OpenRules software, you must obtain OpenRules commercial licenses. To learn more about OpenRules commercial licenses please click here.
