DecisionRules

About DecisionRules

DecisionRules is a business rules engine at the core of a decision automation platform, now adding a decision intelligence layer: audit every decision, analyse what happened, test a better version, and ship it. Engineers integrate it over a REST API and set the guardrails (roles, spaces, versioning, rollback). Business teams update rules as Decision Tables, Trees, and Flows within them, so changes go live without a full release cycle. AI works on top of the deterministic engine, versioned and auditable: the AI Assistant drafts and explains rules around 60% faster, the AI Agent reads documents and returns structured output, and MCP connects to the AI tools you already use. It handles 1B+ decisions a day, and the Solver module evaluates rules in under 10ms. Public cloud, private managed cloud, or self-hosted. Pay as you grow, no feature lock-behind. SOC 2. ISO 27001 certified. Used across financial services, lending, insurance, e-commerce, manufacturing, healthcare, logistics, telecommunications, and government, for credit scoring, pricing, underwriting, claims, fraud and risk, and data validation.
