Errai isn’t really like any other GWT framework. From what I know, DominoKit feels closer to GXT. Errai’s big thing is that it lets you use HTML templates directly within GWT, so you’re not tied to a specific UI widget library. Since it’s built on top of GWT, you still get all the GWT features, but with the flexibility to work with plain HTML and CSS.
On top of that, Errai brings dependency injection to the browser, which I haven’t seen in any other GWT-based framework. From what I can tell, it looks like DominoKit might even use Errai under the hood, but I’m not 100% sure on that.
