Commercial vs. LGPL

Why choose a commercial license?

The Commercial License is the correct license to use for the development of proprietary and/or commercial software with Karto where you do not want to share any source code.

  • Use, modify and redistribute Karto with no obligation to share your source code
  • Get the fully featured SDK
  • Enjoy greater freedom to license your application as you wish

Licensing Options

We are now offering two options to license KARTO:

Karto Open Libraries under LGPL

This allows developers to download a light version of the source code to enable them to modify the code for their own use. Developers have to comply with the terms and conditions contained in the GNU LGPL version 3.
Support services are available separately for purchase.

Karto SDK under a commercial license

This is the appropriate version for the development of proprietary and/or commercial software. This version is for developers who do not want to share the source code with others.


If you want to commercialize a product that relies on the Karto functionalities (for example a robot that uses the Karto mapping library) a runtime distribution license is required. The runtime license price is dependent on volumes and required functionalities and can be as low as $300. To order one or more Karto runtime licenses please contact us.

Purchase and Transfer of Karto SDK Commercial License

The license is sold on a per-developer basis and assigned to a specific computer. We also offer a floating license system that allows multiple developers to share a license. To order a floating Karto SDK licenses please contact us.
