Ruby on Rails vs Node.js – Picking The Right Approach To Web Development

In the late 2004 popular American psychologist, Barry Schwarts came up with a bit counter-intuitive idea, that sometimes having a choice brings much more anxiety and suffering than being left without one. Although his book “The paradox of choice” was mainly about the consumer market, the statement remains true even on the B2B market. The proof is seen when it comes to choosing between Ruby on Rails and Node.js.

We’ve also compared Ruby on Rails with other popular solutions. Read our guide on Ruby on Rails vs PHP and Ruby on Rails vs Django to stay informed!

What is Ruby on Rails?

Ruby on Rails is a framework for Ruby programming language, designed mainly to swift up the code development process and eliminate the bottlenecks of the processes. The framework comes with several important features from the coders’ perspective. The most important is the “Don’t Repeat Yourself” rule, which forces the developer to reuse the components as often as possible, effectively reducing the hidden dependencies within the code and the possibility to ruin something when changes are applied.


Moreover, the framework aims to reduce the amount of required configuration by preparing the environment that is as much ready-to-go as possible.


Hulu is one of the big companies using Ruby on Rails.


The technology is mature, with the first stable version released in 2005 and the latest bigger update, the 6.0.0 version, released in August 2019. The most recent release as of today (early April 2020) is Ruby on Rails from March 2020


Throughout the years, Ruby on Rails was adopted by various web giants, including Hulu, Shopify, Airbnb, and GitHub.

What is Node.js?

Contrary to the Ruby on Rails, Node.js is NOT a framework. The technology is an open-source and cross-platform runtime environment designed to execute JavaScript outside of a browser. The key component of the technology is a Google-designed V8 JavaScript engine, that powers the execution of the code outside the browser.

The project aims to enable developers to use a single programming language throughout the entire project, tackling the traditional separation of front-end and back-end technologies. It is most commonly used in designing the web applications executed in the real-time, like online games and communication tools.



Medium.com is not only based on Node.js, but also hosts the technology’s blog.


The technology is neither the first approach to executing the JavaScript on the server-side nor a recent moonshot. The first stable version was published in 2009 and nowadays, new versions of the framework are usually released two or three times a month. Node.JS 13.0.0 was released back in October 2019 and since then managed to be updated a few more times. At the moment, the most recent release of Node.JS is 13.12.0.


Just like Rails, Node.js is also commonly used by heavyweight IT players, including Microsoft, LinkedIn, SAP and IBM.


As mentioned above, Node.js is not a framework, but a runtime environment. To use it, it is crucial to provide the V8 engine, that comes as an interpreter and compiler, that makes running JavaScript outside the browser possible.


On the other hand, Ruby without Ruby on Rails web development framework remains a powerful and versatile programming language but is much less convenient to use.

Why compare them?

At first glance, both technologies appear to be similar. Both shine in the development of the online project and are used by web giants. Both have die-hard enthusiasts, ready to fight to the end in the internet battles.


The situation is far from being simple enough to provide a fair answer on which one to choose all the time. Considering that, we prepared this short guide to keep you informed.

Ruby on Rails vs Node.js – User Interface

As many web-based technologies, Ruby on Rails comes with many options to design the interface and deliver the user a more immersive and convenient experience. Yet – tools should be used what are they designed for and Ruby on Rails is not an exception. The language is designed to power the application, so leaving all the UX matters in the virtual hands of Ruby on Rails wouldn’t be the smartest move possible.


On the other hand, Node.js descended from front-end to back-end and is basically a javascript enabled to be used on the server side. Although there are ways to use Node.js on the frontend, why one would make life so complicated when the environment on the backend is fully compatible with javascript?

Verdict: none

In the end, you use something else (hint: no matter what you do, you end with JavaScript).



Ruby on Rails vs Node.js – Architecture

Ruby on Rails is a framework, thus the developer is provided with many basic concepts, that powers coding with predefined architectural concepts. The convention over configuration approach enables the developer to focus on designing the code, not to tackle the configuration problems. With Ruby being the object-oriented programming, delivering the consistent and stable architecture is relatively easy.


With the Node.js come all strengths and weaknesses of JavaScript, that is a script language, not designed to deliver and support the backend processes. With the environment come many support functions, yet it is hard to overcome the JavaScript-related limitations on designing modern architecture.

Verdict: Ruby on Rails

Ruby on Rails is a much better tool to deliver a powerful web architecture. Contrary to JavaScript-powered Node.js it was designed to do so.

Ruby on Rails vs Node.js – Speed of coding

Ruby on Rails (and Ruby itself) is one of the modern programming languages designed to be easy to use and to leverage all the modern IT tools. Considering that the Ruby on Rails programmers can deliver the code relatively easy and fast.


Node.js comes with all the power and experience gathered during JavaScript’s years of existence. Thus, there are numerous ready-to-use tweaks. On the other hand, JavaScript provides a limited set of possibilities when compared to the full-scale backend programming language. Considering that, there usually is no straightforward way to solve a problem and the team needs to find numerous detours to reach the destination.

Verdict: Ruby on Rails

Ruby on Rails web development wins in terms of delivering the solution faster. In the end – it was designed to run all the backend work, not forced to do it by the runtime environment.

Ruby on Rails vs Node.js – Performance

Node.js comes with Google-designed V8 engine and it really deserves its automotive-related name. It’s damn fast and its ability to write a high-speed asynchronous code is praised by many web developers. It shines especially in IO heavy operations.


Ruby on Rails is not fully supporting the asynchronous code and concurrency is much harder to achieve and requires more experience from developer. Thus, the performance of Ruby on Rails is visibly lower than in Node.js, although it may still shine in some CPU heavier scenarios.

Verdict: Node.js

Various benchmarks show that the performance of Node.js can be up to 20 times greater than the one provided by Ruby on Rails.



Ruby on Rails vs Node.js – Popularity

The popularity of a technological solution might be sometimes difficult to assess. The battle between Ruby on Rails and Node.js is a great example that confirms this statement.


Let’s start with some raw numbers based on currently live websites. 


Ruby on Rails is used on 1,899% of top 100k sites and 1,285% of top million sites while Node.js is seen on 1,987% and 0,983% respectively. The share exemplifies in 486,763 live websites powered by Ruby on Rails and 191,651 leveraging the Node.js technology.  


Interestingly, Ruby on Rails remains dominant in almost every part of the world except for a handful of places. Here is a quick breakdown of the popularity of both of these solutions in some of the most technologically important countries:


Zrzut ekranu 2020-06-28 o 14.12.13

All the above data is based on the report by SimilarTech as of the 4th of April 2020.


However, the number of live sites shouldn’t be the only way to measure the popularity of the technology. Some sites could be simply built a few years back and left running despite the IT world changing around. As Ruby on Rails was launched around 4 years before Node.js, it simply had more time to become a widely used solution.


So to make sure which technology is really more popular these days, let’s have a look at data from Google Trends.




As it can be clearly seen, since the end of 2013/beginning of 2014, Ruby on Rails is being clearly dominated by Node.js. But it can be also seen that RoR’s popularity is relatively stable while Node.js is in its prime. There are a few different theories of why Node.js is getting such a spike of popularity but the most convincing one is simple — it’s all about JavaScript. It’s the programming language of now, learned by nearly everyone who is trying to get into the world of web development. And with Node.js, the language of front-end has been brought to rule the world of the back-end as well.

Ruby on Rails (and Rails itself) on the other hand, are solutions for developers who tend to look for different, more unique ways of approaching problems. RoR never was and probably never will be a dominant technology among developers — even if it embraces the idea of easily understandable code.

Verdict: not yet

To fully understand how popularity affects the choice between Ruby on Rails and Node.js, we have to look at the other side of the coin — the community.

Ruby on Rails vs Node.js – Community

Even the most robust and advanced technology may become a flop if it doesn’t gather enough developers around itself. If you jump into an online forum for expert developers, you’ll surely find there people talking about some new programming languages and frameworks that are considered interesting but unusable on a larger scale due to the scarce community using them.


The bigger community around technology, the more possible it is that someone already had a similar issue to yours, meaning it can be solved way faster than figuring it out by yourself. That’s why, when considering Ruby on Rails vs Node.js, it’s important to review the popularity of these solutions only within the community of developers.


And one of the best ways to measure the community around the technology is to have a look at GitHub. This is what we did below.


Zrzut ekranu 2020-06-28 o 14.16.55

(Ruby on Rails vs Node.js GitHub data as of 5th of April 2020)


Personally, we would recommend to focus on the number of contributors and commits for each technology. These show the commitment of the community and how active it is the most. And in this category, Ruby on Rails is a clear winner - Node.js might have more stars, but Rails developers are the ones who truly love and explore their technology.

Verdict: Ruby on Rails

The numbers prove that someone who loved Rails once keeps loving it for years to come, actively supporting the community.

Ruby on Rails vs Node.js – Stability

When the technology is backed and used by internet giants, serious problems with stability aren’t usually the case. Both technologies are used by heavyweight internet (and not only!) players and come with numerous users around the web.


The key issues around the stability are not in the technologies, but in the way the users approach them. And that’s where the problems start. JavaScript, apart from being a versatile language with a long tradition of deployment, requires more code to deliver the same functionalities than Ruby on Rails. Considering that, there are many more occasions to insert the bug into the code when delivering the Node.js-based product. Moreover, there are many modules for Node.js that are not-that-top-quality and encountering one can end with the stability issues.

Verdict: Ruby on Rails

The stability is not a case in this context – both technologies are stable and can be trusted. The difference is in modules and extensions, where Ruby on Rails dominates the clash.



Ruby on Rails vs Node.js – Documentation

Both projects provide solid documentation on core components. The rest varies depending on the effort put by the team delivering the component. Considering the less strict approach to programming seen in Node.js, the add-ons may come in a less trustworthy quality than in Ruby on Rails.


Considering that, there is no clear way to point the better one.

Verdict: Draw

Ruby on Rails vs Node.js – The maturity of the platform

Again, both platforms enjoy the support and usage of internet giants. Both are not fresh kids on the block, with Ruby on Rails initially released in 2004 and Node.js in 2009. Moreover, the Node.js is powered and backed by the legacy (seen in a good way) of JavaScript, that is being used since 1995, the times of the dial-up internet and the Netscape Navigator browser.


Both technologies provide stable versions and are developed in regular releases. There are many companies relying on these technologies and looking for ways to leverage them in their projects.

Finally, both technologies can be easily used alongside and integrated with other popular solutions.

Considering that, there is no doubt that both technologies provide a solid and trustworthy base for any web-based project, be that e-commerce or a SaaS product.  

Verdict: Draw

Ruby on Rails vs Node.js – Case studies

Before we proceed with summarizing our findings, it’s good to consider the differences between Ruby on Rails and Node.js on real-life examples.


First, let’s start with Twitter. The famous social media platform is not using Ruby on Rails anymore, but it has been for many years. As some people say – without Rails, we might not have Twitter of today at all. The framework allowed the company to build its popularity fast, implementing new functionalities and improving its web app fast. The rapidness of writing good code is one of the most popular arguments for using Rails.


In the end, however, as we have already mentioned, Twitter moved from Rails. This is because of the scalability and performance issues. When Twitter really became a global phenomenon, Rails started to be not enough for the company’s needs.


LinkedIn has a similar case. They moved from Rails to Node.js due to the need for improving performance. As they have expanded to other countries, including China, the need for a quickly accessible platform for people from all over the world became a must.


We looked at Node and ran some load against it, at which point it would send a request out to something like six otheKiran Prasadr services, grab that data, merge it, and then pop it back out in a fairly simple way. We just ran with that all the way up to about 50,000 QPS (queries per second). Along the way, we discovered that Node was roughly 20 times faster than what we had been using and its memory footprint was smaller as well.

For many global IT companies, however, Rails still happens to be a viable and scalable solution. Years have passed since Twitter stopped using the framework and many improvements have been made. To make sure Rails still answers the modern needs, many of the Rails companies participate as contributors in the development of new versions of the framework.


The list of these companies includes GitHub who was using the beta version of Rails 6.0 and fully migrated to this new version of the framework just after 1.5 weeks after the official release.

By staying current with Rails master, we’re influencing the future of the framework to meet our needs and giving back to the open-source community in big ways. This process means that the GitHub codebase evolves alongside Rails instead of in response to Rails. Investing in our application by staying up to date with the Rails framework has had a tremendously positive effect on our code base and engineering teams. Staying current allows us to invest in our community, invest in our tools for the long term, and improve the experience of working with the GitHub codebase for our engineers.

Summary: beware the mumbo-jumbo

With both technologies being powerful, flexible and mature, it is challenging to pick the winner. It rather depends on the type of web product you want to create.


To make you distinguish the differences between Ruby on Rails and Node.js easier, we’ve set up a quick round-up table below.



Ruby on Rails



Object-oriented Ruby is great for the back-end.

JavaScript, being primarily a front-end language, not designed for the back-end.

Speed of coding

Designed to deliver code rapidly. JavaScript is an older, more traditional solution. Developers might need to take detours to reach their goals.

Learning curve

Ruby is easy to learn, but it’s rarely the first language to be learned by devs. Most developers start their web development career with JavaScript. There is a lot of learning resources, even if JavaScript is slightly more difficult to learn than Ruby.


Lower, especially with a team of inexperienced devs. Great, powered by Google’s V8 engine. Performance up to 20x times better than RoR.


Similar since its best times. Many websites still run on Rails. Constantly growing, surpassed Ruby on Rails in Google Trends a few years back, but still a lower number of sites live using Node.js.


Very active community; if you love Rails once, you’ll always love it. A growing number of devs learn it, but the community still isn’t as active as Rails’ one.


Takes more effort to scale with keeping up a good performance. Easier scalability.

Market share

A number of top companies use it and help in the development of new versions. Some have recently dropped the framework, though, mostly due to issues with scalability. A number of top companies use it, it’s getting more and more popular.

When to use Node.js?

  • When there is a need to use only one language – with the legacy of JavaScript, the company can deliver a complete solution, including, front end, back end, and mobile apps, using only JavaScript. Sometimes that’s fair enough.
  • When there will be a MASSIVE number of requests – Node.js is visibly better performing than Ruby on Rails, so every app that is going to be heavy on requests to the process can benefit from choosing the Node.js over the Ruby on Rails.

When to use Ruby on Rails?

  • When the project is heavy on databases – Ruby on Rails shines when it comes to database management and operations on data. The ability to perform requests with the Ruby on Rails code instead of integrating the SQL code comes with numerous advantages and the swiftness of the process is just one of them.
  • When the clarity is a must – Ruby on Rails comes with numerous best practices and guidelines to follow when developing the project. When combined with the good and clear documentation, the code becomes easy to read, manage and develop by a large, distributed team.
  • When there is a need for rapid delivery – the framework itself comes with all the technologies the web app would need to be launched – the web server, the database, etc. Thus, there is no need for the integration and configuration or looking for the best match. This saves a lot of time and effort and the development team can just sit and start to code.

Key takeout:

Whatever the project you have to deliver, picking the right tool is the first step to victory. What comes later is assembling a team of people who can actually handle the tool well and deliver the project on time and within budget.
