It is integrated in the DMN Engine of the Camunda BPM Platform. However, it can also be used outside of Camunda BPM as a native Scala application or script engine.


  • full support for unary-tests and expressions (DMN 1.2)
  • including built-in functions
  • extensible by own functions and custom object mappers


The FEEL engine can be used/integrated in different ways. The documentation related to the different methods of usage can be found here.
