RadControls for Silverlight are natively built on Silverlight 4 to offer a rich environment for developing robust and lightning-fast line-of-business applications. The suite is engineered for unbeatable performance through UI and Data Virtualization, streamlined themes and templates and more. Sharing the same codebase with Telerik WPF controls, the Silverlight controls offer a clean and intuitive API, Blend support and powerful theming capabilities that will radically improve your RIA development. RadControls for Silverlight provide support for Visual Studio 2010, offering toolbox support, property browsing and WYSIWYG preview for all controls.

RadControls for WPF is the most complete commercial toolset for building next-generation Line of Business and kiosk applications for WPF. Derived from the same codebase as RadControls for Silverlight, the two suites allow for substantial code and skills reuse, enabling you to get the most out of working with Telerik RadControls for XAML. Discover how uncompromising performance, visual appeal and rich capabilities co-exist to deliver a new kind of user experience.

Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.

Gaia Ajax Web Widgets is an Open Source Ajax library for developing Ajax applications for ASP.NET. (2.0 and higher) It is a commercial library, but has a GPL version for developing Free Software with. It has a different approach than most of the other Ajax widgets libraries that mostly update the complete HTML and sends HTML over the net. Instead Gaia has chosen to mirror the control class hierarchy on the client side and post JavaScript updates to concrete objects. It relies heavily on Prototype.js and Scriptaculous in its core and consists of fairly advanced JavaScript code like prototype inheritance and JavaScript "polymorphism". Like Google Web Toolkit, JavaScript is abstracted away, so the developer can develop in the .NET language of choice without knowledge of JavaScript.

Visual WebGui is a platform for rapid development, simple deployment and easy migration of desktop applications and abilities to the web. It is incorporated with an SDK which is integrative to Microsoft Visual Studio, enabling the most productive, secure and responsive desktop-like RIAs (Rich Internet Applications). Visual WebGui is coded using standard .NET languages (C#.NET/VB.NET) and utilizes the productive proven WinForms development paradigm to develop generic web applications including a WYSIWYG forms designer.

CloudGarden's Jigloo GUI Builder is a plugin for the Eclipse Java IDE and WebSphere Studio, which allows you to build and manage both Swing and SWT GUI classes.

Jigloo creates and manages code for all the parts of Swing or SWT GUIs as well as code to handle events, and shows you the GUIs as they are being built. Jigloo parses java class files to construct the form that you use when designing your GUI (round-tripping), so it can work on classes that were generated by other GUI builders or IDEs, or hand-coded classes. It can also convert from a Swing GUI to a SWT GUI and vice-versa.

The goal of this project is to provide a small and cohesive set of powerful UI components with functionality similar to or superseding that of Vista Explorer and Office 2007. The components provide consistent visuals under the existing core and third-party look-and-feels, respect the DPI settings of the user desktop and follow the core Swing guidelines in the external APIs and the internal implementation details.

Altia DeepScreen is a graphics code generator that converts prototype graphics into deployable graphics code. Altia DeepScreen uses the same Altia design that has been a part of the project from the very beginning. To generate code, simply select the design objects that represent the display portion of the product and click on the "Generate Code" menu. ANSI C or Java code is generated in seconds rather than months. DeepScreen was created to remove the tedious, time-consuming task of converting prototype graphics into lines of code.

WUI (Web User Interface) is an MVC framework for writing web UIs in a single language: Java. Write web apps with components, widgets & events, not JSPs. Runs in any servlet 2.3 container. Similar to Model 2 / Struts, only better. Apache-style license.
