Decision Rules Engine
Define complex business logic in a visual table. Deploy a live API in minutes. No code. No per-decision fees. No vendor lock-in.
How it works
Open Ruledeck in any browser. Add your input columns — a credit score, a country code, an order value. Add rows for each outcome. Point and click. No formulas, no code.
Press Publish and Ruledeck creates a live API endpoint your existing systems can call instantly. Your IT team connects it once — after that, business users own the rules.
When a regulation changes or a new product launches, you edit the table, test it in the built-in testbench, and publish again. No change requests. Changes take effect in seconds.
Who it's for
Whether you're processing five decisions a month or five million, the same product handles it. The volume differs. The price doesn't.
Your team makes decisions today using an Excel file that nobody really understands. Ruledeck gives you the same flexibility, with a live API, version history, and an audit trail.
You're scaling fast and regulators want to know exactly what rules ran on which application and when. Ruledeck logs everything and lets non-engineers make compliant changes.
You've been burned by per-decision pricing at scale. Ruledeck is self-hosted, source-transparent, and runs on infrastructure you already own — with no surprise invoices.
Internal approval workflows, eligibility checks, routing rules — your ops team should be able to change these without raising a ticket. With Ruledeck, they can.
Use cases
Approve or decline loan applications based on credit score, income, employment, and requested amount. Change your credit policy overnight without touching the core system.
Return the right price or promotion based on customer segment, basket value, region, or loyalty tier. A/B test new pricing rules before full rollout — built in.
Flag transactions or customers that fall outside regulatory thresholds. Full audit trail of every version of every rule, with timestamps and user identity.
Determine which benefits, products, or services a person qualifies for — in insurance, government services, healthcare, or HR. Rule changes in minutes, not sprints.
Decide which team, system, or process handles an incoming request based on type, value, SLA, or customer profile. Chain multiple rules together for complex flows.
Combine multiple signals into a risk score and route high-risk cases to manual review — automatically. Update thresholds in real time as patterns change.
Features
Build and edit decision tables in any browser. No training required for business users.
Test any rule with real inputs before publishing. Catch mistakes before they reach production.
Every published version is saved with a timestamp. Roll back instantly if needed.
Your existing spreadsheet rules can be imported directly. No manual re-entry.
Run two rule versions simultaneously and compare outcomes. No extra tools needed.
Any system that can make a web request can call your rules. CRM, ERP, website, mobile app.
Full log of who changed what and when, suitable for compliance and governance review.
Rules can call other rules in sequence — for complex multi-stage decision processes.
Performance
Ruledeck handles real-time requests without slowing down your customer-facing processes. All numbers measured on a standard laptop. A dedicated server will be faster.
The rate limiter is configurable per deployment — you control exactly how much traffic any single client can send.
Data & Security
Unlike SaaS decision platforms, Ruledeck runs entirely within your own environment. No decision data, customer information, or business logic is ever sent to an external server.
Install on your own server, data centre, or private cloud. You control the infrastructure.
Every API call requires a valid token. Access is controlled by your IT team.
Ruledeck does not phone home. No usage data leaves your environment.
Data never leaves your servers, making regional data-residency compliance straightforward.
Pricing
Perpetual licence. No subscriptions. No per-decision fees. No lock-in. All tiers include the full feature set.
Whether you make five decisions a month or five million — Ruledeck handles it, and the price stays the same.
