All non commercial projects can be run using our open source code under GPLv2 licensing. As long as your project remains in this category there is no charge. Check out more about our Open Source Philosophy.
If you are working on a prototype that may lead to a commercial product, you can start off using the Open Source Code under GPLv2 for free. However, once the project is commercialised, you need to change to a Commercial license.
Once your end device or application is commercial you need to either open the source code of your end product completely to continue using Cesanta software free of charge under GPLv2 license or alternatively purchase a Commercial license. Keep reading to find out more about commercial licensing.
If you are unsure which type of license is right for you, contact us to discuss.
> The right to develop and modify the software to embed in your own products
> Ability to redistribute your products with Cesanta's software included
> Option to access Software Maintenance & Support for updates, upgrades and technical support
Our license model is simple royalty-free, on-time purchase and includes full access to source code and accompanying documentation. If your needs require a custom license, we’d be happy to work on a solution with you.
Our license model is built around our customers and their specific needs. It is divided into 3 options:
This licence type covers one product which may be delivered in various models
Product Family License
This license type covers a group of products with similar functionality, identical purposes and similar target market
Custom Field License
Custom license for your business across product lines.
This model allows us to be flexible and value-driven towards your integration project.
Simply let us know the details of your project, and we will provide the most effective license option for you.
Integrating Cesanta's software in a commercial product without fully releasing your source code or purchasing a commercial license can have legal ramifications. You agree to the terms under GPLv2 as you integrate our source code.
Incompatibilities, through taking different components of different sources and ignoring any license restrictions, can result in the software pieces you choose not to be permitted to be used in a single product.
