We are talking about a programming framework that was created by David Heinemeier Hansson. This tool is focused on creating websites and combines Ruby (which is a dynamic and multi-purpose programming language) with HTML, CSS and Javascript with the mission of creating web applications that work with a web server.
Despite this, it is also true to say that Ruby on Rails is more than a framework, it is the central project of a giant community that constantly produces libraries to make any complex task of creating web applications much easier.
Something very fundamental to understand why Rails is so important and famous has to do with its effectiveness, and that is what makes it possible for you to build web applications and leave them running online. To give you an idea, the first version of Twitter was made in one day using this tool.
Another important point is that there are more than 800,000 websites that use Rails, including many recognized such as: Walmart, Groupon, Cisco, CNET, IBM, JP Morgan, NASA, Yahoo.
It should be clarified that only in Ruby on Rails you cannot build a mobile application, but you can build a web application and it works as a backend of a mobile application.
We can also have a tool called RubyMotion whose function is to facilitate the construction of iOS and Android apps with Ruby on Rails.
The conclusion then is that with Ruby on Rails, it will not be possible to create mobile applications, but there is something very concrete and that is that it can end up being an essential part of a mobile project.
These are some cases of ruby on rails development company working:
Twitter: Although currently it works with another type of tool to be able to manage the millions of messages in real time, this social network initially worked with Rails.
Hulu: This paid advertising-supported website works with streaming TV shows and movies from NBC, FOX, and many other networks and studios. It currently only works in the United States. It is built with Rails.
Airbnb: It is a company, based on a software platform that is dedicated to offering lodging, different from hotels, to natural persons or tourists in all parts of the world.
Bloomberg: Founded in 1981, it is one of the largest corporations in the world dedicated to the world of finance, with its own news agency and stock software and with more than 15,000 employees. This is one of the largest companies that uses Ruby on Rails.
Groupon: The giant of discounts worldwide. Launched in November 2008 in Chicago, its base is Ruby. Millions of people around the world benefit from discounts on the web daily.
Soundcloud: The YouTube of sound. The Swedish platform manages 175 million unique visits per month and the rise of twelve hours of audio per minute, and has become a reference for both users and creators. It was originally written in Ruby, but like Twitter later adopted Scala for certain parts of the app, although Ruby is still present in the SoundCloud code.
