Differences Between Onion Architecture and Clean Architecture

Onion and clean architectures are both used to create maintainable, scalable, and testable applications by structuring code into layers. Onion architecture is centered around a domain layer with a concentric layer approach focusing on dependency management. Clean architecture, while sharing these principles, organizes code around distinct use cases and emphasizes independence from external systems. The choice between them depends on the priority given to flexibility, business logic complexity, and team familiarity with strict guidelines.
