No, Groovy is used in many other places than Grails. One can think of the Gradle build automation tool (http://gradle.org/), for instance, which uses Groovy as a DSL. But actually, one of the very big use cases for Groovy outside of Grails is as an embedded DSL, for business-oriented languages, to further customize the business rules of an application, for configuring it, etc. Groovy's used in many sectors: healthcare, insurance, banking, travel, scientific simulations, biomedical, etc.

Gradle's the only provable specific example you gave of Groovy being used as a DSL. But is Gradle used for much more than building Groovy, Grails, and Griffon?

Unfortunately, I cannot give some of the real-world DSLs that I know of or that I've worked on, as my customers request that we don't publicize that information.

Just to give you a couple examples which are more or less public, I can mention the Amadeus travel company (whose services are used by 80% of airlines and travel agencies in Europe) or the European Patent Office who did presentations at conferences about their usage of Groovy for DSLs.

The various sectors I mentioned earlier are sectors for which I know companies that are using Groovy for such DSL purposes, although I'm not in a position to publicly speak about them unfortunately :-(

As for Gradle, yes, of course, it's used beyond the Groovy ecosystem. For example, the Spring project (and other related Spring projects) is built with Gradle, as well as Hibernate. Some major projects have switched to Gradle from Maven.

Gradle builds Groovy, Spring, and Hibernate, all software bundled inside Grails. Sounds like Rocher's been busy consolidating the package.
