Vaadin

Vaadin is a web application framework for Rich Internet Applications (RIA). In contrast to Javascript libraries and browser-plugin based solutions it features a server-side architecture, which means that the majority of the logic runs on the servers. Ajax technology is used at the browser-side to ... [More] ensure a rich and interactive user experience. Vaadin is a big collection of UI components. There are server-side components like Button, Table, Tree that you use to compose the application user interface. The components use events, listeners and data binding to communicate with each other and the business logic. The component based architecture together with the data binding features help you to build applications that are easily modularized and refactored as needed. [Less]

Wicket

claimed by Apache Software Foundation

With proper mark-up/logic separation, a POJO data model, and a refreshing lack of XML, Apache Wicket makes developing web-apps simple and enjoyable again. Swap the boilerplate, complex debugging and brittle code for powerful, reusable components written with plain Java and HTML.

Crazy Eddie's GUI System

A free library providing windowing and widgets for graphics APIs / engines where such functionality is not natively available, or severely lacking. The library is object orientated, written in C++, and targeted at games developers who should be spending their time creating great games, not building GUI sub-systems!

qooxdoo

qooxdoo is a universal JavaScript framework that enables you to create applications for a wide range of platforms. With its object-oriented programming model you build rich, interactive applications (RIAs), native-like apps for mobile devices, light-weight traditional web applications or even ... [More] applications to run outside the browser. You leverage its integrated tool chain to develop and deploy applications of any scale, while taking advantage of modern web technologies like HTML5 and CSS3, its comprehensive feature set and a state-of-the-art GUI toolkit. qooxdoo is open source under liberal licenses, led by the world's largest web host 1&1, with a vibrant community.

Clutter Toolkit

Clutter is an open source (LGPLv2.1+) software library for creating fast, compelling, portable, and dynamic graphical user interfaces. It is a core part of MeeGo, and is supported by the open source community. Its development is sponsored by Intel. Clutter uses OpenGL for rendering (and ... [More] optionally OpenGL|ES for use on mobile and embedded platforms), but wraps an easy to use, efficient, flexible API around GL's complexity. Clutter enforces no particular user interface style, but provides a rich, generic foundation for higher-level toolkits tailored to specific needs. [Less]

Qt 5

Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.

Syllable operating system family

The goal of the Syllable project is to create a family of easy-to-use free software operating systems. It is the continuation of the BeOS-like AtheOS. Syllable Desktop has its own C kernel with symmetric multiprocessing, multithreaded pre-emptive multitasking, high POSIX compliancy, 64-bit ... [More] journaled filesystem (AFS) with metadata, an integrated native GUI architecture with an object-oriented C++ API, SDL, singular native toolkit and multi-user desktop environment. The system seeks to be an integrated, lightweight, easy-to-program, powerful, high-performance graphical desktop environment which avoids legacy OS paradigms that frustrate developers and have hindered the computing masses' adoption of a free-software desktop. Syllable Server is a matching small and efficient Linux server. [Less]

Ultimate++

Ultimate++ is a C++ cross-platform rapid application development suite. It includes a set of libraries (GUI, SQL, etc..), and an integrated development environment. Rapid development is achieved by the smart and aggressive use of C++ rather than through fancy code generators. In this respect, U++ ... [More] competes with popular scripting languages while preserving C/C++ runtime characteristics. [Less]

Ample SDK - JavaScript UI Framework

Ample SDK is a standard-based cross-browser JavaScript UI Framework for building Rich Internet Applications. It employs XML technologies (such as XUL, SVG or HTML5) for UI layout, CSS for UI style and JavaScript for application logic. It equalizes browsers and brings technologies support to those missing any.

jSeamless

jSeamless is a UI abstraction layer for Java to allow developers to write code for any platform and any environment (Web, Desktop, Mobile, etc.) without having to know ahead of time the deployment platform or environment will.
