Grule is a rule engine library for Go, inspired by JBoss Drools, with its own Domain-Specific Language (GRL) for defining production rules. It provides an inference engine that matches facts against rules to implement rule-based expert systems.

Use cases

• implement business rules in a Go application
• build an expert system with an inference engine
• separate decision logic from application code
• evaluate conditions and trigger actions declaratively
• replace hardcoded if-else chains with a rules engine
• port Drools-style rule systems to Go

When to choose

• you need a Drools-like production rule system in Go
• business rules change frequently and must be externalized from code
• you want a DSL for declarative rule authoring

When to avoid

• simple conditional logic that doesn't justify a rule engine
• you need a mature ecosystem like Drools on the JVM
• your project isn't written in Go
