Dual licensing refers to the practice of offering a software product or piece of code under two or more different licenses concurrently. This approach is commonly used for open source software projects, where the publisher may wish to provide greater flexibility in terms of licensing options and business models while maintaining some control over the software's intellectual property rights.
The dual licensing model enables software developers and publishers to cater to a wide range of users, including those who prefer the freedom and flexibility provided by open source licenses, as well as those who require the assurances and support typically offered with proprietary closed-source licenses. This approach can also facilitate revenue generation for the publisher, as some users may be more inclined to pay for a proprietary license that includes additional benefits, such as commercial support, warranties, or indemnification.
One of the key advantages of dual licensing is its ability to address the varying needs of different users and use cases. For instance, an open source license may be appropriate for individual developers, non-profit organizations, or academic institutions that seek to benefit from the collaborative nature of the open source community, while a proprietary license may be more suitable for businesses that require stricter protections for their intellectual property or additional support and maintenance services.
In the context of software licensing and open source, there are several popular dual licensing models. One such model involves offering the software under a permissive open source license, such as the Apache License or the MIT License, alongside a proprietary commercial license. This allows users to choose between the open source version, which typically comes without warranties or indemnification, and the commercial version, which may provide additional benefits, such as legal protections or dedicated support. Examples of software products that have adopted this approach include MySQL, Qt, and Red Hat Enterprise Linux.
Another dual licensing model involves offering the software under a copyleft open source license, such as the GNU General Public License (GPL), alongside a proprietary commercial license. In this case, the GPL ensures that derivative works based on the open source version of the software must also be released under the GPL, which may not be desirable for some users or use cases. Those who prefer not to be bound by the GPL's copyleft provisions may opt for the proprietary license, which typically comes with additional benefits such as support and legal protections. Examples of software products that have adopted this approach include Ghostscript, Sleepycat, and SugarCRM.
