The GoRules Playground lets you build, test, and export decision models without creating an account or installing anything.

Open the Playground

Launch the visual editor in your browser

​
What you can do

The playground includes the full visual editor:
  • Decision tables — Create spreadsheet-style conditional logic
  • Expression nodes — Transform data with the ZEN expression language
  • Function nodes — Write custom JavaScript for complex logic
  • Switch nodes — Route data through conditional branches
  • Simulator — Test your rules with sample data and see step-by-step execution

​
Getting started

  1. Open the playground — Visit editor.gorules.io
  2. Build your graph — Drag nodes onto the canvas and connect them
  3. Add logic — Double-click nodes to configure rules, expressions, or code
  4. Test — Click Open Simulator, enter test data, and run your decision
  5. Export — Download the JDM file to use with GoRules SDKs

​
Try these examples

​
Pricing calculator

Build a decision that applies discounts based on customer tier and order value:
  1. Add a Decision Table node
  2. Configure inputs: customer.tier, order.total
  3. Configure output: discount
  4. Add rules for different scenarios

​
Eligibility checker

Create a decision that determines if a user qualifies for a service:
  1. Add an Expression node to calculate derived values (age from birthdate, etc.)
  2. Add a Decision Table to check eligibility criteria
  3. Add another Expression to format the response

​
Risk scoring

Build a decision that calculates a risk score from multiple factors:
  1. Add multiple Decision Table nodes for different risk categories
  2. Add an Expression node to combine scores
  3. Add a Switch node to route to different outcomes based on total score

​
Exporting your work

Click Export to download your decision as a JSON file. This JDM (JSON Decision Model) file works with any GoRules SDK:

Embedding the editor

The visual editor is available as an open-source React component. You can embed it in your own applications: 
npm install @gorules/jdm-editor

import { useState } from 'react';
import { DecisionGraph, JdmConfigProvider } from '@gorules/jdm-editor';
import '@gorules/jdm-editor/dist/style.css';

function RuleEditor() {
  const [graph, setGraph] = useState({ nodes: [], edges: [] });

  return (
    <JdmConfigProvider>
      <DecisionGraph value={graph} onChange={setGraph} />
    </JdmConfigProvider>
  );
}
See the JDM Editor documentation for configuration options, simulation support, and theming.
