Decision Tables
Define business rules in familiar spreadsheet-like tables with multiple hit policies — first match, collect all, or priority-based.
Logic
Visual Decision Engine for Complex Business Logic
Design, test, and deploy decision logic with a visual node-based editor. From simple rules to complex decision trees, Logic gives your team the power to automate decisions without writing code.
Build
Design decisions visually
Compose powerful decision graphs from a library of purpose-built node types. No code required.
Switch Nodes
Route decisions through conditional branches. Define multiple paths with fallback defaults for complete scenario coverage.
Function Nodes
Write custom TypeScript when tables aren't enough. Full access to inputs and context for truly dynamic logic. Use built-in functions and external libraries for calculating loan costs, interest rates, and more.
const score =
input.age * 0.3 +
input.income * 0.5;
return { score, tier: score > 80
? "premium"
: "standard" };
Workflow
From design to production
A streamlined workflow that takes your decision logic from first draft to live in production.
1
Design your decision
Build decision graphs with drag-and-drop nodes. Use decision tables, switch nodes, expressions, and custom functions to model any business logic.
2
Test in real time
Evaluate decisions instantly with sample data. The built-in evaluation panel shows results, trace data, and performance metrics without deploying.
3
Deploy with confidence
Promote decisions through environments with canary routing. Split traffic between versions, monitor performance, and roll back instantly.
Multi-environment deployments
Dev, staging, and production — each with independent configuration.
Build your decisions with powerful tools and modern design.

REST API
Execute decisions via a simple API call. Pass input facts and receive results with trace data and performance metrics.
Multi-tenant isolation
Each tenant operates in complete isolation with dedicated databases and Cedar-based authorization.
Audit trail
Every read, mutation, and execution is logged. Meet compliance requirements with a complete record of all activity.
Canary deployments
Split traffic between versions by percentage. Gradually roll out changes with zero downtime.
Real-time sync
Changes sync instantly across all connected clients. Collaborate on decision logic without conflicts.

This is a real decision table powered by the same Zen Engine that runs in production — compiled to WebAssembly and running in your browser. Edit the input and hit play.
