## What it is
A polyglot rules engine (Ruby, Python, Node.js) for real-time, scalable coordination of events using a Rete-based forward-chaining inference engine implemented in C. It supports rulesets, flowcharts, statecharts, and time-driven flows, with optional state offloading to external data stores like Redis.

## Use cases
- evaluate business rules in real time
- build event-driven inference with forward chaining
- define statecharts and flowcharts for control flow
- correlate events from multiple sources
- build real-time analytics rules
- run complex event processing in Python, Ruby, or Node.js

## When to choose
- you need forward-chaining rule evaluation with fast C-based performance
- you want a polyglot rules engine usable from Ruby, Python, or JavaScript
- you need statecharts, flowcharts, or time-driven rule flows
- you want scalable rule state offloaded to Redis or another store

## When to avoid
- you need a full production-grade BRMS with a UI and decision tables
- you only need simple if/then logic without an inference engine
- you need a JVM-based rules engine like Drools with deep Java ecosystem integration
