Difference Between Ruby and Ruby on Rails

0 upvote


If you are a part of the programming world, you must have heard about them. Today we’re going to talk about the difference between ruby and ruby on rails and the unique purpose they serve in the domain of Web development.


Ruby is an object-oriented programming language that dates way back to 1995. It was developed by Yukihiro Matsumoto. Although it is written in the C programming language, Ruby also contains certain characteristic features of other languages like Perl and Python. Ruby comes loaded with useful features and is extensively used for Web app development. With a simple and neat syntax (just like C and Perl), Ruby is easier to both understand and write, and is hence, a great language choice for beginners.

Despite fashioning a simple and elegant syntax, Ruby was not really a hit with programmers in the past. The real moment of fame for Ruby came with the development of the Rails framework that was built on the core aspects of Ruby. It allows for the smooth and convenient integration of high-level abstractions (for instance, metaprogramming) which further helps in developing a domain specific language.

Ruby on Rails

Ruby on Rails (RoR), better known as Rails, is a web application framework that was developed by David Heinemeier Hansson. While he started developing the Rails framework in 2003, it was made public only in 2004. Written in the Ruby programming language, the Rails framework is based on the MVC (model view controller) architecture. The specialty of the MVC architecture is that it allows data to be delineated from a UI to offer varying possible views of the data. Apart from this, the Rails framework also supports RESTful API. Essentially, Rails was developed to function as a support framework for web application development by facilitating seamless integration of Ruby with JavaScript, HTML, and CSS.

The Rails framework strictly abides by two fundamental concepts. The first one is the DRY (don’t repeat yourself) and the second one is the COC (convention over configuration). Don’t Repeat Yourself, as the name suggests, stresses on the fact that one should never have to repeat the same lines in a code again and again. COC ensures that a code is concise and readable as in it should not contain big configuration files. Instead, it allows you to use a set of default configuration files. Both these principles make sure that a code written on the Rails framework is clean, well-designed, and scalable.

How Is Ruby Different From Ruby On Rails?

Here are the basic differences between Ruby and the Rails framework:

  • Ruby is a programming language that was built on C. Ruby On Rails is a web application framework built on Ruby.
  • Ruby is mainly used to build and develop desktop applications. As mentioned before, RoR is used to develop Web-based applications.
  • While Ruby drew inspiration from languages like C, Perl, and Smalltalk, RoR took inspiration from PHP as well as Django and Laravel of Python.
  • At the core of Ruby lies the principle of user interface design whereas RoR upholds the principles of DRY and COC.
  • The syntax of Ruby is similar to that of C, Perl, and Python. The syntax of RoR is similar to Laravel in PHP, Django in Python, and Phoenix in Elixir.


it can be said that both Ruby and Ruby On Rails have specific features that are best suited for particular domains of application development. However, it is advised that before breaking the ice with Ruby On Rails, it is essential to building a good foundational knowledge of Ruby. and if you’re ever stuck in between the two, carefully assess the requirements of your project at hand, and your dilemma will be solved!
