DecisionRules

Business Rules Engine for Build-First Teams·decisionrules.io

DecisionRules is a no-code/low-code business rules management system (BRMS) and decision intelligence platform, invoked via REST API, that lets business teams define and update decision logic (Decision Tables, Decision Trees, Lookup Tables, Decision Flows, Scripting Rules) while engineers retain architectural control. It combines a deterministic, versioned rule engine with AI features such as an AI Assistant for rule authoring, AI Agents for processing unstructured documents, and a native MCP server for connecting AI tools. It is used for dynamic pricing, credit scoring, claims processing, risk, fraud, and data validation, and can be deployed as public cloud, private managed cloud, or self-hosted on Docker/Kubernetes.
