- Auto AJAX: full AJAX UI from server-side Groovy code
- Instant App: get a full database app from your Groovy domain objects, without writing any UI
- Live Edit & X-Ray: Modify your layout with drag and drop, see through component hierarchy of running app
- First Class Groovy Support: UI components and persistent domain objects can be written in Groovy. Groovy 1.6 is embedded with full project build support for compiled Groovy, and runtime support for on-the-fly Groovy reloading.
Most of the examples are written in Groovy (Java is also supported) as can be seen in these screencasts.
