Free & Web-Based Development IDE: UIzard
UIzard is an open source development tool for creating web applications on the web.
It has built-in support for various project types like:
- standard web applications
- Google API-based widgets/gadgets
- mobile web applications
User interface elements can be controlled with drag’n drops just like a desktop IDE & UIzard’s built-in editor has support for code-highlighting.
With an instant preview feature, the outputs of the design & code can be seen easily.
P.S. The application is currently in beta status & can be a little unstable.
