Open Community Source

The RTI Open Community Source license provides free access to the latest release of Connext DDS software, which includes both library source code and pre-built binaries for the Linux and Windows operating systems. Open Community Source fosters the sharing of a common and interoperable software infrastructure across project teams and organizations.

With Open Community Source, you may:

  • Use Connext DDS without charge for development and deployment.
  • Freely share Connext DDS source code and binaries with other members of your Infrastructure Community (IC). This makes it easy to standardize on a common and interoperable communications infrastructure across a community – even if it spans projects, divisions, companies and organizations.
  • Take advantage of free access to the RTI Support knowledge base.
  • Purchase phone, email and web support on a time and materials basis.
