Grails vs Groovy: What are the differences?
Grails: An Open Source, full stack, web application framework for the JVM. Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features; 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.
Grails can be classified as a tool in the "Frameworks (Full Stack)" category, while Groovy is grouped under "Languages".
"Groovy" is the top reason why over 44 developers like Grails, while over 38 developers mention "Java platform" as the leading cause for choosing Groovy.
Grails and Groovy are both open source tools. Grails with 2.48K GitHub stars and 945 forks on GitHub appears to be more popular than Groovy with 1.49K GitHub stars and 414 GitHub forks.
Starbucks, PedidosYa, and AgoraPulse are some of the popular companies that use Groovy, whereas Grails is used by LinkedIn, PedidosYa, and MercadoLibre. Groovy has a broader approval, being mentioned in 79 company stacks & 73 developers stacks; compared to Grails, which is listed in 47 company stacks and 22 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?
All the power of the JVM, with the ease-of-use of a modern web framework.
