Ruby on Rails (ROR) has become a leading choice for web development. The incredible framework delivers state-of-the-art web apps, helping startup organizations scale up quickly and efficiently. No wonder ROR is the 14th most popular programming language in the world, powering over 5.9% of websites whose server-side programming language is ROR. In this article, we will look at the most popular and high-traffic Ruby on Rails Websites that are developed with RoR, demonstrating the framework’s effectiveness. So, let’s begin. 

What is Ruby on Rails (ROR)?

ROR is an open-source server-side web app framework that was created in 2004. The framework is based on Ruby, which is a dynamic programming language developed over two decades ago by Yukihiro Matsumoto, a Japanese software developer. And even after being so old, Ruby still ranks among the top ten popular programming languages across the globe. 

Rails, or Ruby on Rails, is primarily a software library that further extends the unique capabilities of Ruby. Developed by David Heinemeier Hansson, the framework was originally created to provide developers with a simple language that is much less complicated than Java or PHP. Hansson combined JavaScript, HTML, and CSS with Ruby to create ROR, one of the best programming tools for Ruby on Rails Websites today.

ROR is a comprehensive solution that offers an array of tools to write both client-side and server-side code, enabling developers to easily create the entire structure of web applications. 

One of the best aspects of using this framework is its RubyGems feature. This feature serves as a package manager that allows the creation and quick sharing of specially curated Ruby software libraries called “gems”. There are multiple gems available to suit the specific requirements of any project. Also, with the ever-growing Ruby on Rails community, the number of gems is increasing at a rapid pace.

Ruby on Rails is extensively used for creating new high-performance web platforms and backend solutions. As per the Stackoverflow 2021 Survey, developers claimed that they choose Ruby and Rails 6.75% and 7.04% times among the other available programming languages and frameworks respectively. 

Additionally, it is seen that the number of live websites and web applications developed using the Ruby on Rails framework is over 1 million worldwide

As per Tiobe Index, Ruby stands strong among the 20 most popular programming languages in 2022. And the annual survey by Stack Overflow also shows the language appearing in a similar spot.

Top Websites Built with Ruby on Rails

Over the years, several versions of ROR have hit the market, and each version has further simplified custom app and website development by offering many new and improved gems. Today, developers are using this framework to build different kinds of websites, including social networking sites, eCommerce websites, custom database solutions, and more. 

Here, we will look at the updated list of the most popular websites developed using the ROR framework. So, let’s begin.


1. Twitter

Twitter, the leading news and social networking site is among the top websites based on ROR. It was first developed using ROR and jQuery which enabled the developers to create a fully-functional product in a very short time. Although subsequently, Twitter moved a part of its back-end services to Scala and Java, ROR still remains a part of its front-end layer.


2. Shopify

Shopify is a well-known eCommerce software giant that powers over 600,000 online global retailers. The company offers highly customizable eCommerce websites to retailers for a fixed monthly subscription fee. As one of the best ROR-based companies, Shopify uses the framework to expedite web store development. The company even allows developers to benefit from RubyGems and get access to smart ROR applications quickly.


3. GitHub

GitHub is a software hosting service used by thousands of software developers on a regular basis. The high-traffic website is also backed by an incredibly massive community of 40 million developers who have contributed over 100 million resources so far.

Even today, the website relies on ROR applications to quickly and effectively process the large number of requests encountered each day.


4. Airbnb

Airbnb, the California-based startup, has quickly emerged to become a leading app for all travelers. The app connects travelers searching for a place to stay with hosts who can rent out their apartments. And this app’s infrastructure is largely based on Ruby on Rails. Developers who built the website used RoR in addition to Moment.js, Raven.js, and React.js. ROR is primarily used by Airbnb for its payment stack.


5. Twitch

Twitch is an online video streaming service that is especially popular among the gaming community. The incredible website is ideal for both professional and amateur gamers and has over 1,000,000+ broadcasts every month without any scalability issues.

Groupon serves as an eCommerce marketplace connecting over 25 million customers with local businesses. A lot of people are nowadays subscribing to Groupon to find the best deals on local products, services, and even events. Earlier, the high-traffic website was using Ruby on Rails for its front end. However, subsequently, the company had to switch to Node.js to efficiently scale and manage the increased web traffic.


7. Dribbble

With a network of millions of web designers from across the globe, Dribbble is among the best creative directories.

Ruby on Rails is an excellent framework for almost all kinds of projects, thanks to its extensive library of gems available. The framework follows a quick and flexible development process that radically accelerates the process and ensures the best outcomes. 

Below are some of the most common reasons why ROR is such a popular choice among developers. 

  • High speed: Ruby is a simple, logical, and clear language with a lean codebase. This results in quick and expedited development of web applications. 
  • Flexibility: Ruby on Rails framework is highly flexible. Even if the developers miss out on integrating some functionality in the website, they can do it separately using different modules. Additionally, individual parts of the application can be separately modified and expanded if needed. 
  • Massive community: Ruby on Rails is among the frameworks that have a huge and helpful community. In case of any issue, the developers can discuss the problem and seek solutions from the community members. Also, there are over 1,700,000 RubyGems that can help any developer to enhance the value of their web product. 
  • Scalability: For many years, ROR has faced issues in terms of scalability. However, Ruby on Rails 6 released in 2019 addressed all these issues. The version was considered scalable by default, allowing developers to launch scalable multi-threaded applications. 
  • High reliability and maintainability: Ruby on Rails leverages test-driven deployment or TDD approach. This means that the framework supports extensive testing, thus ensuring highly stable and maintainable solutions. ROR is supported by automated testing tools that make the final product bug-free in no time. 
Ruby on Rails Websites


Ruby on Rails is one of the most sought-after frameworks that is over 15 years old. But even today, the framework is deemed effective, thanks to its features like Ractors and schedulers, extensive libraries, and an active community. No wonder it is still a favorite tool for developers. If you wish to create a feature-packed web application, you must certainly consider this framework. You can get in touch with renowned ROR developers to get started today.
