PhpPeanuts is a framework for developing database-backed applications in PHP. Rather than building an application from the bottom up, you initially only build domain model classes in which you specify properties, relationships, and database table names in metadata. The framework dynamically scaffolds getters and setters, persistency, navigation over relations, and input and delete validation. The abstract user interface instantly offers a rich set of pages for searching, browsing, drilling down, editing and reporting over your domain model. From there on you extend and refine both the domain model and the user interface to make it what you want by defining specialization classes and overriding inherited methods.
Roosevelt is a Web framework for Node.js which uses Teddy for HTML templating and LESS for CSS preprocessing. Built on Express, Roosevelt is designed to abstract all the crusty boilerplate necessary to build a typical Express app, sets sane defaults with mechanisms for override, and provides a uniform MVC structure for your app.
Jenner is a Web page templating system with a twist: it runs completely within a Web browser. Templates are just normal Web pages with special syntax inside text nodes, attributes, or comments. Unlike other in-browser templating systems, Jenner does not require overloading of "class" attributes or invalid HTML; all Jenner templates are valid Web pages and the template expressions flow in a very natural way. Having the template engine in the Web browser instead of on the server takes a lot of load off of the server, and makes for a clean separation of presentation and content. Jenner is very powerful: it has the full power of the Esel expression language at its disposal. Templates can be rendered from JSON data, and can be re-rendered without a browser-to-server round trip.

RMI WebSocket provides a library for remote method invocations between a browser and a Jetty Web Server using the HTML5 WebSocket. The idea is to enable tight method-level integration between the user interface and the server so that patterns such as MVP (Model-View-Presenter) can be applied in a Web environment. The method-level communications between the browser code and the server code allows the developer to think about the Web page and server-side components as objects in a UML world. Details such as the over-the-wire protocols in WebSockets are abstracted away in the process.
