FlexRule Open vs Higson

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, and uses DecisionLang for declarative decision modeling and execution across multiple runtimes. The Open SDK lets technical teams extend DecisionLang with features, custom visuals and integration points 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. Its RESTful API exposes configuration, permissions, security, deployment and decision execution. The authoring platform provides step-through debugging, breakpoints, execution-context inspection and no-code testing for rules, decisions, machine learning and other models. Users can manage and compare versions of artifacts, models and online services, and inspect change history. Connectors include databases, REST APIs, Gmail, Salesforce and Dynamics 365. Pricing is on request.

Higson is a business rules engine for managing product logic, pricing and decisions without coding, with a primary focus on insurance. It supports product configuration, underwriting and claims processing. Higson Studio lets business users edit rules through diagrams, decision tables and a tree structure, then run regression and mass tests using data imported from Excel. Version 4.3 includes a beta assistant that generates Groovy or Python logic from plain-language descriptions. Connections use REST and Java APIs, and supported SQL databases include Oracle, Microsoft SQL Server, PostgreSQL and MySQL. Rule snapshots can be exported to files and imported into other environments. Higson states that it is CREST certified and provides auditability, versioning and permissions scoped by business domain. Enterprise deployment is on-premise or in a private cloud; AWS Marketplace access is also offered. Enterprise costs $10,000 a year as a fixed annual fee, with no limit on users, rules or non-production environments. The Runtime AWS Marketplace listing offers a 7-day free trial that converts to a paid subscription unless canceled.
