Dancer is a Perl framework for building Web applications with minimal effort. It started as a port of Ruby's Sinatra project, but has grown on its own path. A Dancer app can run as a standalone Web server or from any Web server using PSGI. It lets the user write an application with very few lines of code. It's powerful and flexible enough to knock up a simple Web site or Web service very quickly, and can scale to much larger projects. Building a Web application with Dancer is as easy as loading the library and defining route handlers. Dancer provides an elegant syntax for defining route handlers, can render views with a variety of template engines, supports static file serving, session support, and many more features.
WebMotion is a Web application development framework based on a REST architecture and the Java EE 6 standard. It features a presentation layer management using pages (JSP, HTML, etc.) and REST service exposition (e.g. XHR calls). It enables you to serialize service results into JSON or XML. The framework has deliberately limited capabilities, but it focuses on the ease of use. It leaves open the choice of persistence framework, dependency injection, and validation.
