About diffing tool for DMN

Is there any diffing tool for DMN comparison?Something like BPMN diffing tool GitHub - bpmn-io/bpmn-js-differ: A diffing utility for BPMN 2.0 documents.

For DMN difference comparison you can check the signavio modeller.

Is this modeler open source? I can find how to integrate it into my system.
