Crystal vs Groovy: What are the differences?
Developers describe Crystal as "Fast as C, slick as Ruby". Crystal is a programming language that resembles Ruby but compiles to native code and tries to be much more efficient, at the cost of disallowing certain dynamic aspects of Ruby. On the other hand, Groovy is detailed as "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.
Crystal and Groovy can be categorized as "Languages" tools.
"Compiles to efficient native code" is the top reason why over 27 developers like Crystal, while over 38 developers mention "Java platform" as the leading cause for choosing Groovy.
Crystal and Groovy are both open source tools. Crystal with 13.5K GitHub stars and 1.05K 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 Crystal, which is listed in 7 company stacks and 14 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?
i leaving php, node, and python cause i have a new love, crystal
