Sustainability Open Source Software License

A license fee for open source? No reason to panic: Our projects MapProxy, Imposm and Magnacarto are open source and they will stay open source. You can use them in commercial projects, you can read, modify and extend the source code and you can install our software on as many servers as you like. This won't change and you won't have to pay license fees for that.

However, we are now offering you to purchase a Sustainability-Open-Source-Software License – SOSS License – for our open source projects. The SOSS License is a sustainability license with the goal to fund the long-term development of our open source projects.

Why a SOSS License

Technology and standards are evolving and only a project that gets continuous development can be a powerful solution in the future.

However, maintainance and development of open source costs money. Therefore we are asking users of our software to purchase a commercial license to help funding this long-term development.

You should consider purchasing a SOSS License

  • if our software makes your live easier
  • if our software saves your company or agency time and money or
  • if our software is part of your business

and of course, if you have an interest in the future development of our software.

Your benefits from a SOSS License

With the license you will make sure that the software you are relying on gets active maintainance and new development: Bugs get quicker resolved, with frequent releases. New features that will keep you whole system up-to-date.

But that's not all. As a licensee you will also be able to steer the future development. You can choose multiple points where you want to see new development. The more licensees support a single point, the faster the development will proceed.

For MapProxy for example, you could vote for Linux packages or Windows installers, or you could vote for the integration and development of the MapProxy web configuration.

A SOSS License is not a support contract, we offer commercial support separately. The license is only for financing the maintainance and development of our open source projects. However, as a licensee you'll get support for projects on our public mailing lists. Non-licensees will also get help on these lists, but your requests will be prioritized if our time is limited.

How much does a license cost?

We like to divide the development costs among as many people as possible Therefore we offer three different license packages. The small license for 500€ a year is for freelancer or sole proprietorships who use our software in their projects.

For companies and public authorities who are using our software we offer a SOSS License for 2.000€ per year. For larger enterprises, state and federal authorities who make use of our software can purchase a license for 5.000€ per year.

All licensees will get a report each turn of the year with a detailed list of all achieved and planed development. By request, we can also mention you as a supporter on the project websites.

We hope that you are now interessted in our sustainability licenses. You wil find more information on how to purchase a SOSS License on the following page.
