Chief Marketing Officer of Ideamotive. Travel addict and remote work advocate.

At Ideamotive, we just love Ruby on Rails. This amazing framework allows us to deliver state-of-the-art web applications and help startups and businesses of different sectors scale up quickly and efficiently.

We always love to see successful Ruby projects. That’s why we scanned the Web and created a carefully curated list of the largest, most prominent, and simply the best Ruby on Rails companies websites.


Read our blog post and learn what companies that use Ruby in their websites and web apps say about this framework!


And if you want to know even more about Ruby on Rails and how it can help your business, take a look at our free in-depth guide to Ruby on Rails development 👇


1. Airbnb

One of our all-time favorites, both in terms of idea and UX/UI design. This California-based startup connects travelers looking for a place to stay with hosts, who can easily rent their rooms or apartments.


Established in 2007 by 3 postgraduates offering one apartment, the platform offers for their 150 million users more listings than the world’s top hotel chains combined.

Airbnb’s system is based on a variety of technologies, including Ruby on Rails. Developers who created the site used a bunch of libraries, such as React.js, Moment.js, or Raven.js.



2. Groupon

Groupon is a worldwide e-commerce marketplace connecting customers with local businesses. It provides them with special offers and discounts on products or services. With its 50 million customers worldwide and over 1 billion groupons sold, Groupon is probably the biggest player in the sector.


As for the technology used, the original version of the platform was based fully on Ruby on Rails. A few years back, though, as Groupon was growing, they moved to Node.JS.



3. GitHub

If you work in web and application development, you surely know GitHub. It is the most popular software hosting service with a huge open-source library.

The service is now used by 1.8 million businesses, start-ups, and software development companies. It is also supported by the amazing community of nearly 40 million software developers who have contributed to over 100 million repositories so far.


From a technological standpoint, Ruby on Rails accounts for most of GitHub’s code. In August 2019, the Rails 6.0 version of GitHub has been launched.




4. Couchsurfing

Couchsurfing is based on the wonderful idea of creating a global community of travelers who can host each other while traveling the world. Thanks to the system of reviews and transparency, Couchsurfing proved itself to be usually a safe and really interesting way of finding accommodation.


Nowadays, Couchsurfing is a global community of around 15 million users participating in regular events in 200,000 cities around the world. Apart from accommodation opportunities, the platform provides an enormous amount of knowledge about traveling.


As for Ruby on Rails, it is a framework of Couchsurfing’s back-end. Their tech stack includes also Javascript, SCSS, MySQL, SOLR, Redis, and Thumbor.



5. Shopify

Shopify is an incredibly successful e-commerce software platform with over 600,000 online retailers. The company offers easily customizable e-com websites working within the same environment. Retailers simply pay monthly subscription of $29.99 — there is no commission applicable.


Shopify is probably one of the most successful Ruby on Rails-based tech companies worldwide. They have been scaling massively within the framework. Simon Eskildsen from Shopify boosted about being able to address 80,000 requests per second. They also utilize Liquid templating language for the front end and Turbograft, their hard fork of Turbolinks.




6. Ask.fm

If you are over 25 years old, you may have never even heard about this social media platform. But it is extremely popular among millennials and Gen Z, accounting for nearly 220 million registered users. The idea is simple – you ask a specific person a question (be it a friend or a popular Ask.fm celebrity), they answer. Sounds rudimentary? Well, go back to your Quora.


Although we currently see the outflow of users from the website Ask.fm still remains one of the biggest Ruby-based platforms. During the peak moment of existence, the portal attracted 350 million visits per month.


As for the tech stack, apart from Ruby on Rails in the back-end, Ask.fm utilizes also jQuery and AJAX.



7. Dribbble

An amazing directory with graphic design projects by the community of over 500K of web designers from all over the world. Dribbble allows its users to showcase and discuss their work as well as look for career opportunities. In 2017, Dribbble’s users showed off over 640k shots of their work.


The platform was built with Ruby on Rails but also utilizes jQuery and HTML5 History API elements.



8. Twitter

No introduction needed. Twitter is considered the most famous example of a Ruby on Rails-based product. It was initially created with RoR and jQuery which allowed the platform’s creators to develop a fully working product in a very short period of time.


Although a few years later Twitter was re-written using Scala, Ruby still remains a part of the back-end and reminds about the platform’s roots.



9. Etsy

Etsy is an e-commerce platform built with the aim of connecting retailers of handmade and vintage products with potential suppliers and clients.Think of Etsy as a huge bazaar or flea market with almost 2 million merchants and over 50 million registered users.


This e-commerce system is one of the pioneers of modern-day startups. Choosing Ruby on Rails allowed Etsy to maintain a strong database, easily implement additional features and conduct a series of systems integrations.



10. Fab

Fab is a design-focused marketplace, dedicated to helping customers discover beautiful and unique wellness/fitness products. The platform offers thousands of items, from pieces of art to clothes and tech gadgets. They all have one thing in common – beautiful design, which makes Fab a perfect place for aesthetes and high-quality design lovers.


Fab uses Ruby on Rails as its main framework with Ruby being the main language. It also utilizes Backbone.js and New Relic.




11. SlideShare

SlideShare is a slide hosting website with over 70 millions visitors monthly, currently owned by Microsoft. It allows users to store and post their digital presentations (PowerPoint, Keynote, etc.), text documents and videos.

In 2012, SlideShare was acquired by LinkedIn which was later bought by Microsoft.



12. Hulu

Hulu is a video streaming platform currently available only in the United States. It is smaller than Netflix and HBO GO but growing fast and releasing new, great shows every month. Despite its availability in only one country, there are currently around 28 million active subscribers of Hulu.


Ruby on Rails was with Hulu since the very beginning and they love this framework there.

The ideals of Rails – convention over configuration. Don’t Repeat Yourself (whenever possible, reuse as much code as possible rather than duplicating similar code in multiple places). Test first, and agile – are quickly becoming pervasive throughout software development.

stated Matthew Butt, ex-Hulu development manager.


Although the platform was re-written, RoR is still used in their back-end with Backbone.JS used in the front-end.



13. Kickstarter

In our opinion, this is one of the best Ruby on Rails companies' websites. This amazing platform allows you to seek funding for your project or support other people's ideas. Almost 150,000 projects were successfully funded via Kickstarter so far, including Oculus Rift or Wasteland 2.


We have also seen much weirder projects, e.g. combat kitchenware (a frying pan attached to a sword) or digging a hole without any reason whatsoever.

Kickstarter is one of our favorites RoR-based websites in terms of UX/UI design with a user-friendly interface and intuitive user path.


Service itself was built with Ruby on Rails framework and Perl language with the main libraries being jQuery, React, and History.js.



14. SoundCloud

SoundCloud is a Berlin-based startup originally created to allow musicians to share music with each other. Since then though, it developed into a full-on publishing platform allowing emerging artists to showcase and promote their music. With nearly 80 million registered users and over 200 million tracks submitted, SoundCloud is a pretty amazing place to look for new tracks and musical inspirations.


SoundCloud attracts mostly alternative, non-commercial, and niche artists. If you’d like to find a set of this DJ who recently played in Berghain, you will not be looking on Youtube or Spotify. He will be on SoundCloud.


SoundCloud was born on Ruby on Rails. It allowed the platform to iterate fast and keep high-quality code. Due to the enormous growth, SoundCloud was latter re-written using JVM.



15. UrbanDictionary

Urban dictionary is a fantastic place when you need to check the meaning of every slang word or create a new one (hoping that somebody will actually start using it). It’s also full of alternative definitions of well-known terms (e.g “programmer” – is a human, rock, or any other object capable of turning pizza and caffeine into code.)


The dictionary is based on the Ruby on Rails framework, along with special frameworks like Heroku Vegur Proxy and Foundation.  As for JS frameworks, React was used.


Urban dictionary

16. Basecamp

There would not be any Basecamp without Ruby on Rails and probably no Ruby without Basecamp. Both our favorite framework and this popular project management online tool was created by the same man – David Heinemeier Hansson.


Ruby on Rails is proven to be extremely successful in Basecamp growth.Getting from 45 accounts in 2004 to over 2 million in 2016 required scaling up quickly and effectively. Ruby on Rails developers from Basecamp did a great job there.
