FEEL Scala
A parser and interpreter for FEEL that is written in Scala (see What is FEEL?).
The FEEL engine started as a slack time project, grown into a community-driven project, and is now officially maintained by Camunda. :rocket:
It is integrated in the following projects:
- Camunda 7 as part of the DMN engine
- Camunda 8 (Zeebe) as the expression language
- DMN-Scala as part of the DMN engine
Features: :sparkles:
- Full support for unary-tests and expressions
- Including built-in functions
- Extensible by custom functions and object mappers

Please have a look at the documentation. It describes how to write FEEL expressions (e.g. data types, language constructs, builtin-functions, etc.). Or, check out examples and learning resources here.
Want to try it out? Use the Playground to evaluate FEEL expressions.
