Groovy vs JRuby: What are the differences?
What is Groovy? A dynamic language for the Java platform. Groovy builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. It makes modern programming features available to Java developers with almost-zero learning curve.
What is JRuby? A high performance, stable, fully threaded Java implementation of the Ruby programming language. JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information.
Groovy and JRuby can be categorized as "Languages" tools.
"Java platform" is the top reason why over 38 developers like Groovy, while over 7 developers mention "Java" as the leading cause for choosing JRuby.
Groovy and JRuby are both open source tools. JRuby with 3.32K GitHub stars and 830 forks on GitHub appears to be more popular than Groovy with 1.49K GitHub stars and 414 GitHub forks.
According to the StackShare community, Groovy has a broader approval, being mentioned in 79 company stacks & 73 developers stacks; compared to JRuby, which is listed in 13 company stacks and 4 developer stacks.

Some may wonder why did we choose Grails ? Really good question :) We spent quite some time to evaluate what framework to go with and the battle was between Play Scala and Grails ( Groovy ). We have enough experience with both and, to be honest, I absolutely in love with Scala; however, the tipping point for us was the potential speed of development. Grails allows much faster development pace than Play , and as of right now this is the most important parameter. We might convert later though. Also, worth mentioning, by default Grails comes with Gradle as a build tool, so why change?
