ObjectForge is a small factory library for Ruby objects with minimal assumptions about framework, persistence, or runtime environment. It is designed for cases where factory-style object construction is useful, but Rails-oriented or database-oriented tooling is a poor fit. ObjectForge works well with plain Ruby objects, hashes, arrays, structs, and custom build flows. The library focuses on explicit configuration, independent registries and factories, and replaceable components. It aims to provide a familiar workflow without coupling object generation to a framework or persistence layer.
