Groovy is the leading open source dynamic language for the Java Virtual Machine that offers a flexible Java-like syntax that most Java developers can learn in matter of hours. Groovy provides features seen in other dynamic languages like Ruby, Python or Smalltalk. Groovy really shines in its ability to easily define internal Domain Specific Languages (DSLs) that can be used as an abstraction layer that enables non-technical subject matter experts to codify business rules.

Grails is an advanced and innovative open source web application platform that delivers new levels of developer productivity by applying principles like Convention over Configuration. Grails helps development teams embrace agile methodologies, deliver quality applications in reduced amounts of time, and focus on what really matters: creating high quality, easy to use applications that delight users.
