Why GoRules?

The business rules engine built different.

Most rules engines are stuck in the past - slow, expensive, locked to the cloud. GoRules is native, fast, and runs anywhere. Here's what makes us different.

Truly Native

Not an API wrapper.

Most "SDKs" are lying to you. They claim support for Python, Go, Node.js - but under the hood? Just a REST call wrapped in a library. Every decision hits their server. Every millisecond of latency is your problem.

GoRules is different. Our ZEN engine compiles to actual native code. It runs in your process. On your device. In microseconds.

❌ THEM

✅ GORULES

Runs Everywhere

Cloud. Self-hosted. Mobile. Edge. Air-gapped.

The same engine runs everywhere - not different products stitched together. Build once, deploy anywhere.

Cloud

Managed BRMS. We handle infrastructure.

Self-Hosted

Your VPC. Your data. Docker or K8s.

Mobile

Native iOS and Android. On device.

Edge & IoT

Warehouses, kiosks, devices.

Air-Gapped

Fully disconnected. Still works.

No Per-Eval Pricing

Unlimited decisions. Predictable costs.

Most vendors charge per evaluation. Sounds cheap at first - until you're running millions of decisions a day. Then it kills you. GoRules is flat-rate.

No surprises. No meter anxiety. No "we need to optimize our rule calls" conversations.

Open Source Core

Audit every line.

Our ZEN engine is fully open source. Not "source available" with restrictions. Not "open core" with all the good stuff behind a paywall. Actually open.

Why? Because we believe critical business logic shouldn't be a black box. You deserve to see exactly how your decisions are made.

Fork it if you need to
Self-host forever - even if we disappear
Community contributions welcome
No vendor lock-in - your rules are portable JSON

Built for Both

Business users and developers. One platform.

Rules engines usually pick a side - either dumbed down for business users, or powerful but dev-only. We refuse to choose.

For Business Users

Spreadsheet-like decision tables
Edit rules in Excel, import back
Visual flow builder - drag and drop
No code required
Test with real data before publishing

For Developers

Git-like workflow - branches, commits, rollback
Full JavaScript functions when you need them
Native SDKs - not wrappers
CI/CD integration
Microsecond-level performance tracing

Same graph. Same rules. Different interfaces for different people.
