Ruby on Rails vs Node.js. Which to Choose for a Startup?

Statistics have shown that the hardest decision for a startup has to do with choosing a technology or language to use.

However, in the midst of this dilemma, the top most popular languages and frameworks, Ruby on Rails and Node JS tend to have a huge debate as to which is better for startups.

In this article, we will have a look at the comparison of RoR vs Node JS, together with the attributes of these two technologies. You’ll see the reason for this argument so that startups of this kind of situation can easily make a quick decision.

Check out: Ruby on Rails for a startup.

Ruby on Rails

Ruby is an object-oriented language that sums up important features of other languages, while Rails is an application framework built around the Ruby language. Ruby on Rails has quite a number of benefits that make it appealing for startups. These benefits are:

  • – rapid application development
  • – good code quality
  • – large community
  • design-friendly
  • – saves time and effort
  • – enables you to write fewer codes
  • – has good libraries

Pros of Ruby on Rails

Startups tend to go for Ruby on Rails not just because of the benefits, but the pros as well. Here are the pros/advantages of using Rails:

  • – cost-effective as you tend to spend less
  • – easy to code which applies also to refactoring codes
  • – fast delivery process from initial idea to users, and saves your time and money
  • – suitable for all business

Cons of Ruby on Rails

It is often said that whatever has a good side always has its downside. It will be unfair to look into the benefits and pros of Ruby on Rails without talking about its cons.

  • – runtime speed of Rails is very slow, as compared to other languages
  • – multithreading leads to performance issues
  • – boot speed is slow and takes more time than usual to start
  • – ActiveRecord as your domain becomes tightly coupled with your persistence mechanism
  • – usually hard to find good documentation


More on Pros and Cons of Ruby on rails



Node.js is an open-source platform for executing JavaScript code server-side, as it was built on the JavaScript runtime. With the help of event-driven, non-blocking I/O model, Node.js tends to be more efficient and lightweight. Node.js has its advantages and disadvantages. Further, we will see it’s pros and cons.

Node.js Pros:

  • – full package from HTTP server to templating engine
  • – client and server side has the same language
  • – simple to deploy, monitor, and provide support for
  • – page loading is faster
  • – high demand rate in the market
  • – powerful underlying libraries

Node.js Cons:

  • – not suitable for intensive processor tasks
  • – unstable API
  • – does not have a standard library
  • – most of the codes will have a JavaScript problem
  • – requires the Asynchronous Programming Model, which many developers find more difficult

Node.js vs. Ruby on Rails Comparison

Comparing Node.JS vs Rails is like comparing a mango and guava.

Node.js is an application runtime environment that allows writing on the server-side application using Javascript, while Ruby on Rails is a framework.

Take a look at the core difference between Node JS vs Rails

Node.JS Ruby on Rails
Flexibility Node.js is very flexible and can do things out of the box, but you will have to write some code and install some modules. Ruby on Rails is not a flexible framework and makes you adhere to its way of doing things out of the box. You have to build your app in a particular way.
Setup Node.js gives you nothing but a fresh install. Rails, on the other hand, gives you a lot more than a fresh install, which includes generators.
Development process Node.js takes more time, as you need to find the modules and follow the instruction for integrating them. Ruby on Rails seems to be faster, as you can perform some task, like database migration, with just a few commands.
Learning curve The learning curve is partially less than with Rails. It is flexible and understandable for developers with or without any prior background. Though learning Rails is easy, you might need to know and understand the attributes, like objects, classes, Ruby-level methods, etc. that are important and take considerable time.
Finding Talent Depends on the market: for instance, it is quite easy to find Node.js developers in the USA, while in some European regions this task may be tricky. It can be hard to find Ruby on Rails developers with good experience. The popularity of each technology depends on the market, but finding an experienced developer is always challenging.
Pricing The price for developing your application using this framework tends to be higher because it takes more time. On the contrary, you tend to pay less because Rails helps you develop your project faster.


In conclusion, it is not that easy to choose a tech stack for a startup.

Startups have to consider looking into their business model and analyzing the pros and cons of both technologies, which means making a decision is by preference.

Both Node JS and Ruby on Rails can help you achieve the same results, but Rails is perfect when you want to move at a high pace. When building your application, the language or framework doesn’t really matter, but the execution is important. Analyze the pros and cons features and then get started.
