Benefits of using GWT
- I18N support
- Strongly typed language benefits: No JavaScript syntax errors
- Tooling support: eclipse, etc.
- Debugging support
- Unit Testable
- Compiled to specific targets: no browser specific code
- Cross browser support
- Users are familiar seeing/using GWT widgets: Google application suite and many other Web 2.0 apps
- Able to use 3rd party libraries via JSNI (JavaScript Native Interface)
- Rapid development using GWT tools such GWTShell etc.
- 3rd party tools for producing WYSIWYG UI
- MVC implementation that is very similar to programming in AWT/SWING
- "When working with GWT as a developer, it's best to think of it as an analogue to the Java Abstract Windowing Toolkit (AWT). It's the basis for your application framework, not the framework itself."
- GWT4Gadgets: Support for iGoogle Gadgets / OpenSocial Apps / Google Mapplets
- Offline applications using Google-Gears
- Full access to the GData APIs
- Supports GWT-RPC, REST, WS, etc. communication to back-end, and or Data-APIs

- Accessibility support: ARIA support on FireFox 3+, or FireFox2 with FireVox
- Works with Java-Applets and or Flash
- Optimizes out redundant metadata from JSON communication to reduce bandwidth cost of client-server communication
