Millstone Licensing Guidelines

Millstone follows the following rules of thumb for its licensing:

Free for learning, development and testing
Commercial deployment license is required for deploying any program that uses Millstone libraries to production use
For distributing Millstone libraries as a part of your own product, there is two alternatives:
Purchasing commercial deployment licenses for each deployed copy of the product.
If you plan to deploy at least 5 copies of the product, you can contact IT Mill Ltd for OEM-license tailored for your products needs.

When I can use Millstone for free?

Development of applications and products using Millstone tools and libraries is complitely free. Furthermore, you can deploy the developed program for testing and validation at the development time. Any production (or real) use of the deployed program with Millstone libraries requires commercial deployment license.

When I must obtain a commercial license for Millstone

A deployment license is required for each deployed copy of a program that uses Millstone libraries. To be more exact, each Java Virtual Machine (JVM) that runs a program that uses Millstone libraries, must an unique commercial deployment license. For example, if the program is deployed to multiple servers (for load balancing or other reasons), each server needs an unique license. Deployment for testing the program during development phase is permitted without a license if the deployed program is not used for any production or real use.
