FlexRule Open vs GoRules BRMS

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.

GoRules BRMS is a platform for creating, testing, reviewing, and releasing business rules with version control, approvals, and an audit trail. Decision models can use tables, expressions, JavaScript functions, and switch nodes. Teams can test rules against sample data and scenario suites, while the editor flags type and syntax errors during editing. Drafts, history, visual diffs, branches, and commits track user-attributed changes. Immutable releases can move from development to staging to production unchanged, or roll back to an earlier release. GoRules AI can draft table and graph changes, create and run tests, explain decisions, and draft policies, but it does not deploy releases. The ZEN Engine has SDKs for Node.js, Python, Go, Rust, Java, Kotlin, C#, and Swift, plus REST API integration. The BRMS can be self-hosted with Docker and PostgreSQL on cloud platforms or Kubernetes. The Free plan lists two users and one project, with no deployment environments. Pro costs $167 a month, billed annually. GoRules does not support DMN.
