Streamlined is a framework on top of Rails that allows you to quickly generate interfaces for your ActiveRecord models. It started as a way to generate Administrative backends, but has become more general purpose over time.

Specifically, Streamlined aims to bring the declarative goodness of ActiveRecord to the view layer. It manages the presentation, creation and editing of instances of your models, with full-featured scaffolds that include relationship management.

Streamlined is a Rails plugin, although in previous versions it used to be a generator.
