FlexRule Open

What FlexRule Open is
FlexRule Open combines data, business intelligence, rules, and AI for enterprise decision intelligence in regulated environments. It supports Decision Model and Notation at Conformance Level 3 and Shared Data Model and Notation, with DecisionLang for declarative decision modeling and execution across multiple runtimes. Technical teams can use the Open SDK to extend DecisionLang, add features, create custom visuals, and build integrations without source-code access. Deployment can be in the cloud, on premises, or at the edge, including embedded, browser, client, and REST API service execution. The RESTful API exposes configuration, permissions, security, deployment, and decision execution. Authoring tools include step-through debugging, breakpoints, execution-context inspection, and no-code testing for rules, decisions, machine learning, and other models. Teams can manage versions of project artifacts, models, and online services, compare changes, and inspect change history. Pricing is on request. FlexRule says it does not hold customer data in its system and supports access levels and role-based access in FlexRule Server.
