Liberty
A minimalist web-framework for Ruby that gets out of your way so you can focus on your most valuable asset — your business logic.
Liberty is the state of being free from oppressive restrictions imposed by authority.
Liberty is also a minimalist web-framework for Ruby that seeks to get out of your way so that you can focus on your most valuable asset — the part of your application that is uniquely yours — your business logic.
Liberty is structured in a way that encourages you to separate your business logic from the underlying framework code. It provides a web adapter for a Hexagonal Architecture, and it works very well with Domain Driven Design.
