In Short: The Delta Engine is Open Source and you can use its basic tools freely on your PC, improve it and even build and sell products created with them. Deployment on other platforms and advanced features and support require a license to our platform cloud services.

The Delta Engine is community driven and continually developed by the Delta Engine company to provide: 

  • 100% free usage on Windows
  • Available in C# (.NET), more languages possible later (Java, C++, JS, etc.)
  • Libraries and samples are 100% open source under the Apache license (see below)
  • Affordable pricing for indies and companies alike: Pricing
  • Internal development is currently funded through project work, we eat our own dog food!
