What problem does it solve?

The Firefly Rule Engine provides a YAML DSL and multi-module architecture to define, parse, evaluate, and audit business rules with a reactive runtime and optional Python compilation.

Core Features & Use Cases

• YAML DSL for rule definitions, including inputs, constants, when/then/else, and complex conditions.
• AST-based parsing and evaluation with support for audits, validation, and REST APIs.
• Multi-module structure (interfaces, models, core, web, sdk) and a Python compilation option for offline execution.
• Use cases include defining credit checks, eligibility workflows, and batch rule evaluations across services.

Quick Start

Provide a YAML rule that encodes a simple business decision and evaluate it using the Rule Engine to obtain outputs and audit trails.
