Ruby on Rails’ websites have been spreading across the media for over twenty years now. It is time-tested, reliable, agile, and object-oriented which makes it a great option for many marketplaces, real estate, streaming, and even data analytics applications. The popularity of Ruby is globally recognized, and the TIOBE index in 2024 shows Ruby among the top 20 programming languages, right beside Kotlin and Swift.

Many websites across the web leverage this technology, and in this article we will swiftly brush up on the top 30 most intriguing examples. Here’s a sneak peek: among the most famous Ruby on Rails websites are headliners like Goodreads, Airbnb, and Twitch. 

So, without further ado, let’s look at the most famous examples of Ruby on Rails implementations.

What is Ruby On Rails

Ruby on Rails is actually not just a programming language, but rather a framework that consists of two parts: Ruby programming language and the Rails software library that extends its capabilities.

  • Ruby

Developed more than twenty years ago by Japanese software developer Yukihiro Matsumoto, Ruby still ranks as one of the top ten most popular programming languages. Matsumoto stated that programming tools should be developed so they’ll be easier for humans to use, not for machines to understand, so it is very user-friendly, and designed specifically with usability in mind.

Ruby is a general purpose language. It can be used for various software development tasks, but it’s especially effective in web application creation.

  • Rails/Ruby on Rails

Rails, also known as Ruby on Rails, is a software library that extends the capabilities of Ruby programming language. In simple terms, it’s program code that is added to Ruby to make it more versatile and add more features. Rails was created in 2003 by David Heinemeier Hansson, when he grew disappointed with the more common languages like Java, which he thought was unnecessarily complicated, or PHP, which was full of repetitive code. He combined HTML, JavaScript and CSS with Ruby, and created one of today’s most popular programming tools.

Now, RoR is a framework for the creation of a wide variety of websites. It is used for creating server-side (or back-end) web applications, i.e. those that run on the server (the applications that run on the user’s browser are called “front-end” applications).

Another core feature that makes RoR awesome for developers of Ruby on Rails sample projects is its RubyGems feature. RubyGems is a package manager that enables the creation and sharing of Ruby software libraries, called “gems”. There are many useful gems for all sorts of situations available on the dedicated RubyGems website, and are easy to download and use. And with the huge community Ruby on Rails has, new gems are appearing as fast as new issues in programming arise.
