They are not. It's a third party fork that's keeping it alive. It's dead because Google didn't put any resources into it and just threw it out to see if it sticks. Then didn't keep up with the capabilities of JavaScript frameworks and didn't release any proper templates.

Did gmail migrate off GWT?

It never used GWT. They claimed GWT can be used to build apps like gmail and that was misleading. They didn't write it using GWT since it predated the existence of GWT.

Thanks. Did any well known Google apps use GWT?

[invalidname]

I think Wave was written in it... Not sure if there were others.

When I checked 2-3 years ago, Google Cloud portal was based on GWT.
