D-Level uses an open source-friendly business model called Dual Licensing. Dual licensing is a business model that allows software development companies to provide commercial software licenses for a fee to their customers, while at the same time offering their software under approved open source licenses.

Our licensing options include:

• The D-Level Commercial License, which allows you to provide commercial software licenses to your customers or distribute D-Level products-based applications within your organization. This is for organizations that do not want to release the source code for their applications as open source / free software; in other words they do not want to comply with the GNU General Public License (GPL).

• For those developing open source applications, the D-Level Public License allows you to offer your software under an open source / free software license to all who wish to use, modify, and distribute it freely. The Open Source License allows you to use the software at no charge under the condition that if you use D-Level products in an application you use or redistribute ,the complete source code for your application must be available and freely redistributable under reasonable conditions.
