"RIFE is a full-stack web application framework with tools and APIs to implement most common web features. Its design provides the best of request-based and component-based approaches in a consistent component object model. RIFE's engine provides a solution that values maintainability without compromising on productivity. Through a centralized site structure, an application can be split up into easily reusable binary modules that can be seamlessly integrated into other projects."
