You can use this page to identify the documented licensing models for MDriven Designer, MDriven Turnkey, and MDrivenServer, and to understand the restrictions that apply to source-code access.

Licensing overview

MDriven licenses may be usage-based, calendar-based, or negotiated with MDriven, depending on the product and deployment scenario.

License area Documented terms Example
MDriven Designer, Turnkey Server, and Local MDriven Server The free option is for personal projects and exploration, runs on your own device, and has a maximum of 50 classes. A model with 35 classes can be explored locally under the stated free-option limit.
Usage-based licensing Registering for usage-based services removes the 50-class limit. Use of MDriven Designer with a larger model consumes more MCoins than use with a smaller model. If you expand a model from 50 to 80 classes and use usage-based services, the class limit no longer applies.
Calendar-based licensing Calendar-based licenses are yearly unless another period is specified. A team can obtain a calendar-based license for a specified period.
MDriven Turnkey A Turnkey subscription applies to the site that holds your application. Pricing can scale with usage, and there is no fixed monthly overhead as the user base fluctuates, while additional performance needs may trigger extra costs. A site with more users does not have a fixed monthly overhead solely because its user base fluctuates, but a need for additional performance can affect the cost.

Source-code license

A source-code license gives named developers at a licensing company access to MDriven Framework source code for debugging the MDriven product. It is an optional additional license and provides access rather than a sale of the source code.

The source-code license is issued to a named developer in the licensing company. It remains with the company if that developer leaves; the company must provide the name of a replacement developer. Source-code licenses are available only to corporations, not private individuals.

The delivered source includes C# code for compiling the runtime and design-time parts of the MDriven Framework for Visual Studio and the MDriven Designer plug-in for Visual Studio.

Confidentiality and permitted use

You may use supplied source files only to debug the MDriven product. The files are confidential information and must be protected with at least reasonable care. Do not disclose them to third parties.

You must not:

  • Modify, adapt, alter, translate, or create derivative works from the source files.
  • Merge the source files with other software.
  • Disclose, lease, rent, loan, sublicense, distribute, or otherwise transfer the source files or any part of them to a third party.
  • Remove, alter, or obscure confidentiality, copyright, trademark, or other proprietary notices.
  • Reproduce or use the source files except where the license expressly authorizes it.

For example, if you inspect a source file to diagnose a runtime defect, you may use it for that debugging purpose. You must not patch the file and distribute the patched version to another organization.

Local source changes are discouraged and should be temporary until MDriven issues an official fix.

Choose and obtain a license

  1. Determine whether you need local exploration, usage-based services, a calendar-based agreement, MDrivenServer operation, MDriven Turnkey hosting, or source-code access for debugging.
  2. For calendar-based licensing, source-code access, or a negotiated production arrangement, contact MDriven at sales@mdriven.net.
  3. If ordering source-code access, provide a scanned and signed purchase order. European customers must include their VAT-ID.
