Monolithic Clean Architecture

Free WMS uses the same battle-tested architecture — combining Clean Architecture principles with the simplicity of a monolith.

Clean Architecture

Application, Domain, Infrastructure, and Presentation layers are clearly separated. Each layer has distinct responsibilities, making the codebase maintainable and scalable.

CQRS + MediatR

Commands and Queries are separated into distinct handlers. MediatR pipeline behaviors handle validation, logging, and transactions without polluting business logic.

Headless API

Fully decoupled backend API enables seamless integration with any frontend. Complete REST API with Swagger documentation and JWT authentication.
