It is a no-code/low-code Business Rules Management System (BRMS). Engineers integrate it over a REST API and set the guardrails (roles, spaces, versioning, and rollback), and business teams model and update business rules within them, so changes go live without a full release cycle. Go live in days, not months. Professional Services available. Pay as you grow. No monolithic suites. No paying for features that sit on a shelf. Add use cases, users, and environments at your own pace, with public cloud pricing on our website. Built for enterprise scale. The platform handles 1B+ decisions a day, and the new Solver module evaluates rules in under 10ms. SOC 2 audited. ISO 27001 certified. Build together, not around each other. Model business rules with Decision Tables, Decision Trees, Decision Flows, and Scripting Rules, with instant testing, version control, and full audit trails. No coding required for business teams; full REST API access for developers. AI, on a deterministic engine. DecisionRules puts AI on top of a stateless evaluation engine, so what AI helps you build still runs the same way every time, versioned and auditable. The AI Assistant works inside the editor to draft, test, and explain Decision Tables in plain language, and reduces rule authoring time by around 60%. The AI Agent is a native rule type that reads documents and narratives and returns structured, typed output. Through the native MCP integration, connect DecisionRules to the AI tools your team already uses. Flexible deployment. Public cloud, private managed cloud, or self-hosted. Available on AWS Marketplace and Microsoft Azure Marketplace. Industry applications: financial services (credit decisioning, loan origination, fraud and risk, KYC/AML), insurance (underwriting, claims, fraud), e-commerce (dynamic pricing), manufacturing (pricing, quoting), telecommunications (offers, eligibility), healthcare (eligibility and benefits rules), logistics (routing, capacity), aviation, and government (benefits, compliance). Frequently Asked Questions: Who uses DecisionRules? Enterprise architects, engineers, and business teams, across financial services, insurance, e-commerce, manufacturing, healthcare, logistics, telecommunications, and government. They automate credit scoring, pricing, underwriting, claims, fraud and risk checks, and compliance workflows. Does DecisionRules require coding? No coding is required for business teams to build and manage rules with Decision Tables and Decision Trees. Developers can use Scripting Rules and the REST API for advanced integrations. How does DecisionRules use AI? AI works on top of the deterministic engine, so results stay versioned and auditable. The AI Assistant helps build, test, and explain Decision Tables in plain language. The AI Agent reads documents and returns structured output. Through MCP, DecisionRules connects to the AI tools your team already uses. Is DecisionRules secure? DecisionRules holds SOC 2 and is ISO 27001 certified, with role-based access control, audit logging, and encryption at rest and in transit. ![DecisionRules](https://images.g2crowd.com/uploads/product/image/large_detail/large_detail_17b20c0b91615fb8cf2c11ff3530fb61/decisionrules.png "DecisionRules") DecisionRules Discussions Most CommentedMost HelpfulCommon QuestionsNewest Showing **1** discussion ![Pinned by G2 as a common question](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Pinned by G2 as a common question") G2 Pinned by G2 as a common question • over 4 years ago More Options - Share [![linkedin](/assets/social-logos/linkedin-afe65e46604a5bd5105ab9c856116204040b6b3f2b2d42562fc8071ca0c48ca0.svg "linkedin")](https://www.linkedin.com/shareArticle?mini=true&summary=What+is+the+best+rule+engine%3F&title=What+is+the+best+rule+engine%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-the-best-rule-engine) [![twitter](/assets/social-logos/twitter-61aaec80434c71387b8f7326e480592eae71c0a65afd051d66fce9b75a9bf417.svg "twitter")](https://twitter.com/intent/tweet?text=What+is+the+best+rule+engine%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-the-best-rule-engine&via=G2dotcom) [![facebook](/assets/social-logos/facebook-350d0b410d6b10debcf893050e803a8633d53561aa42807b087b8daf9be3668f.svg "facebook")](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-the-best-rule-engine) [![gmail](/assets/social-logos/gmail-6db42f21e7c254fae201b112bef0dd15d25223a5cbb32691ce80eab43761eadf.svg "gmail")](https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=&su=What+is+the+best+rule+engine%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-the-best-rule-engine%0aWhat+is+the+best+rule+engine%3F) [![mail](/assets/social-logos/mail-d55c53b04bf49872e40cd2443b85a99caa23394e6cf154ae32a9d08377c15d86.svg "mail")](mailto:?subject=What+is+the+best+rule+engine%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-the-best-rule-engine%0aWhat+is+the+best+rule+engine%3F) - Copy link - [ ## What is the best rule engine? ](/discussions/what-is-the-best-rule-engine) What is the best rule engine?
