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.

What is Crystal?

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.

What is Groovy?

It is a powerful multi-faceted programming language for the JVM platform. It supports a spectrum of programming styles incorporating features from dynamic languages such as optional and duck typing, but also static compilation and static type checking at levels similar to or greater than Java through its extensible static type checker. It aims to greatly increase developer productivity with many powerful features but also a concise, familiar and easy to learn syntax.
