3Why not use Drools? – Codo May 13 '21 at 11:19

I would like to have alternatives. – user1800752 May 13 '21 at 12:52

@user1800752 so a better question would be "is there an alternative to Drools" because there is already an open-source and availabile via Maven library that implements the FEEL language – Luca Molteni May 17 '21 at 08:14

We warmly invite you to check out Drools, it is written in Java, it is open-source (Apache-2.0) and available via Maven Central
It also powers Kogito for cloud-native (K8s) Quarkus-based or SpringBoot-based decision services using DMN/FEEL.

I would expect that all products achieving a good score with the DMN Technology Compatibility Kit and providing a Java library would fulfill your requirements.
Drools and Camnunda would certainly qualify, possibly also jDMN and Actico (as they are Java based). For the other ones, I don't know if they are Java based.

Unfortunately, the Camunda library is written in Scala. Anyway, except for Camunda and Drools, the vendors you suggest do not implement FEEL-language as a Java library provided by the Maven repository. – user1800752 May 13 '21 at 12:44

So open-source and availability via Maven are additional requirements then. – Codo May 13 '21 at 13:12
