DecisionRules

What it is

DecisionRules is a cloud-native business rules management system (BRMS) "built around Decision Tables, Decision Trees, Decision Flows, and Scripting Rules". It evaluates rules through a REST API. The reader it is for is a business team that owns the rules (analysts, risk teams, pricing teams) paired with engineers who call them from an application. The company's own explanation of why a BRMS exists is that rules change far more often than the systems that use them: it gives the examples of a bank updating risk thresholds quarterly, an insurer adjusting underwriting criteria by region and an e-commerce platform tweaking pricing rules weekly, and says that with a BRMS those updates happen in a visual editor and go live without a software release. It is not a form builder or an app builder. It is a decision layer you put behind an API, which is why it sits in this directory's process automation and API builders groups. The pages do not state where the company is based.

What you build and how

Rule types. You pick the model that fits the logic. Decision Tables suit high-volume conditionals and are authored in a spreadsheet-like interface. Decision Trees handle branching logic. Scripting Rules cover custom calculations. Lookup Tables hold reference data, such as country codes, fees and product configurations, separately from the logic, so business users can update that data without touching the rules and without SQL. The company says templates get you started and that the path from a business requirement to a working rule takes minutes rather than sprints.

Decision Flows. A flow chains Decision Tables, Scripting Rules and API calls into one visual workflow, moving data through evaluation and transformation stages "without writing integration code". The company's comparison page also says the product has a workflow and flow builder, and that it externalizes the decision logic that otherwise gets buried in process flows: if you already run a BPMN tool, your BPMN tool handles orchestration and DecisionRules handles the business rules.

The API side. Your application sends input data, the engine evaluates the rule and returns the decision. The company says the same pattern works from a CRM, an ERP, a core banking system, a loan origination platform or a custom application, and it says integration takes hours for most teams. Developers can sign up for the free tier, build a Decision Table and call it by API; the company says most developers have a working rule inside 30 minutes. Beyond the REST API, the comparison page names an MCP Server, webhooks, and native n8n and Zapier integrations that connect onward to tools such as Slack and Google Sheets. That is the api-builders angle: you are not building a front end here, you are publishing a decision as an endpoint.

Versioning and release. Every change is versioned. You can test before deployment, compare changes side by side and push through CI/CD pipelines. The comparison page adds that rollback is one click for business users and does not require Git knowledge. It also lists A/B testing and simulations among the built-in features.

Office and BI tooling. An Excel add-in lets business users test, validate and bulk-run rules, one row or thousands of records at a time, without involving IT. A BI API and a dedicated Power BI connector export execution data so you can build your own analytics on what actually happens in production.

AI. The company describes two AI capabilities. The AI Assistant is a build-time helper: describe what you need in natural language and it can create Decision Tables, Scripting Rules, Lookup Tables and complete Decision Flows, generate test data, write and explain functions, summarize existing logic, work with uploaded documents and recommend templates. The AI Agent is a runtime rule type that uses large language models during execution to interpret unstructured information. Document intelligence feeds PDFs, Excel files and scanned documents into decision flows, and a bring-your-own-model option is listed. With Explainable AI switched on, every AI Agent result carries a confidence score, the reasoning and the source passages it used.

Deployment. The comparison page lists 3 deployment options: Public Cloud, Private Managed Cloud and Self-Hosted. The pages shown give no hosting region.

People and services. The company has in-house training and onboarding, plus professional services for architecture design, rule migration and production support, offered in three engagement models from full project delivery to on-demand expert hours. A network of certified partners covers the USA, Europe, LATAM, APAC and Africa.

What the pages say

Free trial and free tier. The comparison page says the free trial has every feature available, with no credit card required and no functional restrictions, and that afterward you can continue on a free tier with reduced limits. It adds "your first rule in under 5 minutes". The pages shown do not give the limits of the free tier.

Pricing. The company says it offers transparent pricing across Public Cloud, Private Managed Cloud and Self-Hosted models and that you add use cases, users and environments at your own pace. No plan names or figures appear on the pages shown. It says the paid plans of Nected, a competitor, are gated behind "View Pricing", which is the company's own claim about another vendor.

Security. The site says "SOC 2 and ISO 27001 certified" and lists SSO, role-based permissions and a full decision audit trail. The comparison page adds execution-level audit logging.

AI numbers. The company says its AI claims come from a controlled experiment: about 60% faster rule authoring, a 3x daily productivity increase and 80% of chat sessions rated very helpful. These are the vendor's own measurements.

Support. An enterprise SLA with a 1-hour response for critical issues is available. The comparison page shows a G2 High Performer badge. A review quoted on the home page, from an enterprise architect at COOP Bank, says DecisionRules "nails the balance between user-friendly UI and powerful logic".

Who it suits and who it does not

DecisionRules suits a team where credit, pricing or underwriting logic changes often and where analysts, not developers, should make those changes, while engineers keep control of deployment. The financial services and insurance examples on its pages, plus SOC 2 and ISO 27001, make it a fit for a regulated enterprise that needs every decision explained. The self-hosted option appeals to a team that must keep it inside its own infrastructure. Its comparison pages target teams moving off other rules engines such as Drools and IBM ODM.

It is a poor match for anyone who wants to build screens, forms or a full app: there is no user interface builder described, and orchestration of long-running human tasks stays with a BPMN tool. A solo founder with a handful of if-then rules may find a rules engine more than they need, although the free tier makes a trial cheap. The pages do not publish plan prices, so budgeting needs a conversation or a demo.
