Ruby is a versatile, dynamic, and interpreted language for object-oriented programming. The language is similar to written English, so even someone who doesn't really know how to code can, to some extent, understand code written in Ruby.
However, coding sites in Ruby is a tedious job. That is why a special tool was created to optimize the development process: Rails.
9 years after the release of Ruby, the Ruby On Rails (ROR) web development framework was created at Basecamp in order to
facilitate the programming of applications to create complex websites. It also marked the beginning of the massive popularity of Ruby and the arrival of companies built on Ruby on Rails, such as Capsens for example. It is our core technology ❤️
Why Ruby on Rails? The main objective of Ruby is to quickly create new and efficient web platforms. However, there's really no definite answer when it comes to using Ruby because, like any general-purpose programming language, it's suitable for a wide range of programming tasks. No web development company would treat code as something that exists outside of a project's commercial goals. Each programming language, each technology stack is designed to solve certain problems. So, depending on the objective, RoR may or may not be the right choice for your web project (but most of the time it's the right one;)).
What types of projects is Ruby on Rails best for:
The number of websites and platforms created using Ruby on Rails is over one million in the world (over 4 million of which existed at any given time), and that number is constantly increasing.
RoR is also strongly oriented towards developers who particularly appreciate it.

Ruby on Rails is one of the favorite technologies for startups. The list of companies that use Ruby on Rails includes abroad: Airbnb, Shopify, Kickstarter,... And in France companies such as Doctolib, Sorare, Qonto, Qonto, Pennylane and others. In other words, Rails is something that can be considered “made for business.”
Moreover, RoR is particularly used in companies whose product is “tech”: Github, for example, is coded in RoR. Closer to us, the school 42 intranet is also in RoR.
So what are the qualities of Ruby on Rails and why did these companies decide to use RoR for the development of their web projects? You will find the list of the qualities of this framework This other article.
