Super Charge Your Startup Product with React + Ruby on Rails


If you are an entrepreneur planning to launch a product, there might be many questions in your mind, like, what tech stack is right for your product? Or, which technology will help you reduce the technical debts, ensure future viability, and ensure security?

Well, you are not alone in this boat.

Before building a product, one of the most important things to consider is the technology stack as it lays the foundation on which a product needs to be developed. So, it is good to be as analytical as possible while choosing the right one.

At Netsmartz, we do a lot of analysis about client requirements before recommending any tech stack. And, recently, many of our clients asked us about the buzz around using React with Ruby On Rails (RoR). Many of them wonder whether RoR is still a framework worth using in 2021. The answer is “Yes” and this blog lists many reasons why

What is React?

Developed by Facebook, React is a front-end JavaScript library used for developing reusable UI components or beautiful user interfaces. It lets developers build large-scale web apps that can update the requested data without reloading the whole web page. Due to its amazing features like virtual DOM, one-way data binding, and component-based nature, it has been used by Fortune 500 companies for developing web apps. Some of the amazing properties of React include:

  • Component-based architecture
  • Server-Side Support
  • Virtual DOM
  • Native Approach
  • Seamless Performance
  • Mobile Support
  • Easy Testability

What is Ruby on Rails?

Ruby on Rails is a web framework based on Ruby, a programming language developed in the 90s. The goal behind creating RoR was to create a framework using which developers can build high-performing web apps fast. ROR is a Model-View-Controller (MVC) full-stack framework and the entire code in it is separated into layers. While Model contains high-level classes, View contains data that users interact with and Controller connects both of them. Here are some of the properties of dedicated ROR developer that make it a perfect fit for a startup:

  • Mature and evolving
  • Time and cost-effective
  • Vast ecosystem
  • Free-to-use
  • Perfect for building MVPs

What Makes “React + Ruby on Rails” a Perfect Solution?

Here are six solid reasons why React and ROR is a match made in heaven for startups:

1. Less Server Response Time

What irritates users most while using a web app is slow loading. While the website load time depends on a number of factors like web page design, browser, hosting server, speed of internet connection, an ideal web app should load within 2 seconds.

A Google study shows, as page load time increases, the number of page views decreases.

Any website taking more than two seconds to load would push users away which nobody desires. However, when using React with ROR, websites load fast as the combination reduces the server response time by up to 70%.

2. Accelerated Time-to-Market

If you are a startup and want to test your idea faster, React with Ruby on Rails can do wonders for you. Especially, if your business model is freemium, this combination would help you save a lot of time and money. It also works well when creating single-page applications using React on the frontend and ROR on the backend.

Another important reason is that if you are just planning to test the market, you will get success or failure a lot faster with this magical combination to make future decisions.

3. Reliability and Stability

The combination of React and ROR is used by big brands like Twitter, Airbnb, and many others. Thus, it is one of the most trusted tech stacks for building dynamic web apps. Whereas Ruby on Rails is backed by a big and strong community, React is a library supported and maintained by Facebook. Thus, you can expect your app to be stable and developed with amazing efficiency with React and ROR.

4. Less Memory Usage

In case you’re confronting issues related to memory usage, deploying an app using ROR and React would be an ideal solution. A perfect example of this is – a brand that improved memory usage and response time after using this magical tech stack. After this deployment, their app’s performance improved as well.

5. Simplicity to Use

With a well-defined lifecycle, component-based structure, and use of just plain Javascript, React is simple to use and learn. It uses a syntax called JSX which lets developers mix Javascript and HTML to build professional web and mobile apps easily and without wasting a lot of time handling complexities.

On the other hand, ROR also has an intuitive and easy-to-use syntax that lets programmers accomplish more in less time. ROR developers can develop a web app faster by writing less code. Moreover, the framework ensures the highest readability and code is more understandable. Thus, when you combine both these technologies together, you can achieve wonders.

6. Easy Business Logic Implementation

When using Ruby on Rails, implementation of business logic is not a problem no matter how complex it is. For example, you can create the APIs you need faster using ROR and save time. And when you pair it with a feature-rich front-end framework like React, it becomes a win-win situation, for developers as well as business owners.

3 Brands that are Using the Magical Combination of React + Ruby on Rails

When choosing the right tech stack from a pool of technologies, it helps to take lessons from big brands. Here are three companies using React with Ruby on Rails for delivering amazing experiences:


We all are fans of the seamless and engaging experience that Airbnb offers. Well, it is developed using Ruby as the primary programming language, React for creating UI, and Rails for the server-side configuration. Isn’t this an amazing choice?


Gusto is an online payroll platform that uses React and Rails for processing billions of dollars on its platform having a large user base. Rails and React provide them the agility and accuracy required to handle huge transactions with ease and security.


Opendoor is one of the best real estate websites in the USA. It is the first choice for anyone who plans to buy or sell a property in the USA. When they started building their platform in 2014, they chose ROR and Angular to develop an MVP. But, later on, they shifted to React.

Final Words

As a tech startup founder, you need to make sure the technologies you select to build your product are robust enough to support your business needs and sustainable enough to support your expansion plans. Ruby on Rails on the backend with React on the frontend is the best approach for most new companies.

However, is RoR with React an ideal solution for all types of applications? Absolutely not! Just like no one size fits all, there is no ideal tech stack that suits all types of web applications. For example, if you plan to use high-end technologies like Blockchain or Machine Learning in your app, it won’t work well.

But, if you plan to develop a dynamic app that supports microinteractions, it is a perfect choice. If you need to know more, drop us a message. We’ll be eager to assist you in accomplishing your business goals.
