The document compares the Ruby on Rails and Groovy on Rails frameworks. Ruby on Rails is built on the Ruby programming language and uses an active record approach, while Groovy on Rails is built on Groovy and Java and uses a domain-oriented approach. The document discusses factors to consider when choosing between the frameworks like skills, community support, and deployment options. It notes that Ruby on Rails is more established while Groovy on Rails may be easier for Java developers.

INTRODUCTION
Have you ever wondered as to what these terms are – Ruby, Groovy, Rail and got confused as to what
all this is about? Which one to choose? Which one is better and which is not? Well then here is a blog
which I write with the intention of making things clear between Ruby on Rails and Groovy on Rails.
Rails was founded by David Hansson and is an open source web application development framework
which can produce powerful web applications at a fast pace. It was first released in July 2004.
Applications built using Rails automatically inherit the best practices concerning security, performance
and stability . It uses a programming pattern called MVC (Model View Controller) that differentiates
the business logic (Server) and presentation (Client), adding to the ease of development and
maintenance of codes. Even top companies
like Twitter, GitHub, Basecamp, YellowPages and Shopify are using Rails.
Grails is one of the most popular open source Java Web Development framework built on Java EE,
Spring, Hibernate & Quartz. It was released in 2008 & is now owned by Mware.

Normally when you build any application, you need Database Management, User Interface, Service
Layer and Configuration.
Both Rails & Grails framework provides you all these. That’s why it is called full stack. Grails uses
Groovy which is an agile, object oriented & dynamic programming language for JVM(Java Virtual
Machine).
If we compare the similarities between Rails & Grails, then both are used for rapid application
development which is easy to configure and produce. Both work on principles of convention over
configuration, scaffolding and don’t repeat yourself (DRY).
Now comes the tough part of deciding which one to choose. Before we can conclude as to which one to
choose let’s first check out the differences between both the frameworks so that we can compare &
select the best one out of it based on your preferences:

3. ACADGILD
So choosing among the framework depends upon what skill set you have. If you want to maximize
advantage of your existing Java skills or have developers experienced in Java than go for Grails. But if
you are more accustomed with Ruby, HTML, CSS and JavaScript then go for Rails.
Other factors which will influence your choice are the available career opportunities, community,
documentation support, development & deployment time for either one of them.

Ruby on
Rails or Rails
Groovy on
Rails or Grails
Ruby is a scripting language that is based on C and
requires a Ruby interpreter, usually written in C.
Groovy is a scripting language that is based on
Java and requires JVM to run it.
Rails framework is used for developing Web applications
for Ruby.
Grails framework is used for developing web
applications for Groovy.
Rails can be deployed on servers like FastCGI, Jboss
Portal, Mongrel &
JRuby+GlassFish.
Grails can be deployed on many popular J2EE
servers like Tomcat, Jboss, Weblogic, IntelliJ
Ultimate, Jetty & GlassFish.
It follows database oriented approach. It follows a domain oriented approach.
It supports only dynamic typing. It supports dynamic as well as static typing.
Rails setup is a bit painful, especially on Windows. Grails is easy to setup.
Rails framework is lightweight and requires mediocre
memory & CPU.
Grails framework is heavy and requires more
memory & strong CPU.
Rails ORM is based on ActiveRecord which is limited but
is an evolving framework.
Grails ORM is based on Hibernate which is an
industrial strength ORM framework.
The learning curve is longer than Grails since Rails operate
on Database model. The learning curve is fast for Java developers.
It has many successful user stories, including twitter.com,
groupon.cometc. It also has lot of job opportunities. It
has the highest popularity in StackOverFlow. Most of the
questions were already asked and solved.
Grails is quite young as compared to Rails. The
community and documentation is not as good
as Rails. There are very less job opportunities.
