Drools Fiddle is the fiddle for Drools, a business rule engine maintained by Redhat: https://www.drools.org/. The goal of this web tool is to allow technical or non technical users to play around with Drools. First, it allows you to build your business configuration by defining both fact models and business rules. Secondly, you can simulate the evaluation of your rule package by dynamically instanciating facts in the Drools working memory and trigger the fireAllRules method. A set of features have been implemented in order to enhance the user experience: step by step debugging, contribution, graphical visualization.
