FlexRule Open vs OpenL Tablets

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.

OpenL Tablets is a business rules engine and decision management system that uses structured Excel tables as executable application logic. It supports Excel formats dating back to Excel 97, with tables for decisions, lookups, spreadsheet calculations, decision trees, and algorithms. OpenL Studio provides a web interface for editing and managing rules, including guided authoring, inline cell editing, and type-safe checks that point to errors. Rules can run as REST services, Kafka consumers or producers, or providers for Java interfaces; they can also be used in Maven projects and work with Java classes and methods. The repository can use Git, databases, and blob storage, with versions, metadata, WebDAV access, and role-based permissions. Analysis tools include tracing, explanations, tests, benchmarks, what-if analysis, and checks for gaps and overlaps. Deployment features include effective and expiration dates, staging, consistency checks, and live updates. The free demo bundle runs in single-user mode and includes a local Git repository with examples and tutorials.
