The Grails Framework was inspired by the popular Ruby on Rails (see https://en.wikipedia.org/wiki/Grails_(framework) )
The main difference is that Ruby on Rails required developers to learn the Ruby language, whereas Grails is based upon the Groovy language which is effectively an extension of the Java syntax (see https://groovy-lang.org ).
For developers with Java expertise, Grails can be easier and faster to learn than Ruby on Rails (see https://rubyonrails.org ).
Most importantly, it offers many of the same benefits:
- Object Relational Mapping to the database layer similar to Java Hibernate (see https://en.wikipedia.org/wiki/Hibernate_(framework) )
- Integrated web server and Groovy Server Pages (see https://gsp.grails.org/latest/guide/index.html ).
- Security framework based upon Spring Boot (see https://livebook.manning.com/book/spring-boot-in-action/chapter-6/26 )
