8 Famous Apps Built on NodeJs

Several well-known applications use Node.js for a variety of reasons. We know you’ve been bombarded with articles about NodeJS, about how fantastic JavaScript is, and about how JavaScript is nearly conquering the world of web development. However, this article is going to be so different. Here we will be trying to portray how well is NodeJS and why the top companies are building their tech based on it.

You may be shocked to learn that many applications that you use daily are developed on the NodeJS platform. If you are interested in learning more about the names of these applications, we have compiled a convenient list of well-known organizations that have used NodeJS for their applications. Before we get started, let me give you a brief introduction.

What exactly is NodeJS?

NodeJS is a javascript runtime environment that is free and open-source. Previously, Javascript was only helpful for developing client-side applications; however, the power of Javascript has now reached the server-side, and you can utilize Node.js to develop the back-end services for your application. It is lightweight, scalable, quick, and extremely pleasant to work with for developers to use.

That being said, without further ado, here are the top ten most popular NodeJS applications available today.

Popular Node JS Mobile Apps

1. PayPal

Elon Musk is a name that is now widely known around the world. PayPal, which Elon Musk co-founded, is the largest and most commonly used online payment service in the world today. PayPal opted in 2013 to transition its programme from Java to Javascript and NodeJS, with over 200 million users and over 100 currencies.

Why NodeJS?

PayPal’s engineering teams were divided into two groups: those who developed for the browser (using HTML, CSS, and JavaScript) and those who worked for the server (using Java), which created a significant dilemma for the company’s developers. As a result, the best answer was to adopt Javascript, a single language that could be used for both the browser and the server.


  • With fewer workers, the software was produced almost twice as quickly as it might have been.
  • Compared to the prior Java-based programs, the new application has 33% fewer lines of code and 40% fewer files, making it significantly lighter in overall weight.
  • NodeJS helped increase the number of requests serviced per second twofold while reducing the average response time by 35%.

2. Netflix

I do not feel that this application requires any more explanation. Netflix is the world’s leading supplier of video streaming services, including movies and television programs, and is available in more than 190 countries worldwide. The company had more than 81 million customers throughout the world as of April 2016, with more than 46 million in the United States alone. The Node.js programming language was used to create the whole Netflix user interface.

Why NodeJS?

The developers chose Node.js to offer a lightning-fast, modular, and lightweight application. They wished to reduce the time it took for the application to start up. When dealing with a high-traffic video content source such as Netflix, speed and load time were crucial factors to consider. Because their frontend had previously been created in Javascript, the team looked for an excellent and rapid solution.

NodeJS was the ideal answer for them. Because the developers were already familiar with javascript, it was easy to pick up on the various runtime environments quickly. NodeJS also contains many modules, allowing developers to get the task done more rapidly by relying on these modules rather than building certain functionalities.


  • The application’s starting time was decreased by 70% due to this improvement.
  • The development process is expedited because just one language is used for both the client and the server sides.
  • Customization by the user is now possible.

3. LinkedIn

LinkedIn is a professional networking and career-building social media platform. With over 675 million users in 200 countries and regions worldwide, LinkedIn is available in more than 24 languages. Moreover, guess what? Node.js power the server-side of LinkedIn’s mobile application.

Why NodeJS?

The new mobile app has incredible speed, consumes less memory, and is 20 times quicker than the old Ruby on Rails-based version. It also has a smaller footprint. Furthermore, resource consumption has been significantly improved, resulting in a tenfold reduction in the number of servers required to execute the mobile application!


  • Because of this, they have freed up resources and decreased the number of servers from 30 to 3.
  • Client-side performance has been improved by up to ten times due to the increased traffic capacity.
  • They sped up the development process by merging the teams previously working separately on the front-end and back-end into a single group responsible for both.

4. Uber

With its cab app, Uber is a transportation network corporation best known for its ride-hailing services. Uber is currently accessible in 85 countries and over 900 cities throughout the world, and it completes more than 14 million rides every day on average. By implementing a new business model, the corporation could alter the course of transportation history.

Uber was one of the first firms to put Node.js into total production when it created an extensive matching system using the Node.js framework. Thus, as a result of the technology choice to utilize Node, Uber’s app significantly improved its performance, processed information more rapidly, increased the operating speed of the service, and issues could be addressed instantly without the need for a restart.

As a result, Uber can now process more than 2 million remote procedure calls (RPCs) every second, even when faced with large volumes of traffic.

5. Godaddy

GoDaddy is a web domain hosting firm with more than 13 million clients and hosts more than 61 million domains. They picked Node JS mobile app because it aided them in developing high-quality applications, adding new features, and having access to the Node Package Manager (NPM).

Because of Node JS, they were able to reduce their reliance on servers tenfold while maintaining the speed and functionality of the application. Node JS allows GoDaddy to handle all of its functions with only a tenth of the hardware they were utilizing in the previous version.

As Stephen Commisso, Senior Software Developer at GoDaddy, explains, utilizing Node makes it simple to construct a high-quality application, publish new features fast, perform unit and integration tests effortlessly, and work with REST. Another important aspect is access to the NPM.

The programme can now handle the same amount of demand with only 10% of the available hardware.

6. Groupon

Subscribers to Groupon’s worldwide e-commerce marketplace may save money on activities, travel, and other products and services by purchasing them at a discounted rate from local merchants. In 2019, Groupon operated in 15 countries worldwide and had more than 48 million active clients, according to the company.

As of June 2015, the firm announced that the entire Groupon web and mobile traffic from the Ruby on Rails application to a new Node.js stack had been completed successfully.

The reasons are simple scalability, a dynamic community, Node.js Package Manager (NPM), and performance. These are based on the former enterprise Node.js developer at Groupon, Sean McCullough.

In comparison to the previous Ruby on Rails platform, web pages have improved by around 50% in speed and have the ability to handle significantly more traffic.

7. eBay

eBay is a global e-commerce corporation based in the United States that provides consumer-to-consumer and business-to-consumer online sales services. It is completely free for customers to use; however, fees for listing and selling things are charged solely to sellers.

According to Statista, the service is available in 32 countries (as of 2019) and has 182 million active users in the second quarter of 2020.

Speed and simplicity, performance, scalability, a sense of transparency and control, single-threading, managing I/O-bound tasks, and not-blocking I/O are just a few of the criteria that the corporation deemed to be in its best interests.


Isn’t it a strange choice for a name like this to appear in a list of Node.js examples? Although you may be surprised to see NASA’s name on this list, NodeJS has assisted NASA in keeping its astronauts safe.

Bringing our species to the edge of the universe is a monumental undertaking; the system is intended to give as much protection to humans as possible in the vast and hostile vacuum of space, and NodeJS was instrumental in preserving the lives of astronauts.

In 2013, Luca Parmitano, a NASA astronaut, was involved in a potentially life-threatening event. His spacesuit began leaking water into his helmet, and NASA was tasked with investigating the cause of the leak. Following this event, NASA decided to develop their own end-to-end data system, which they implemented using NodeJS.

However, because of the system’s existing design, it was discovered that this was not a straightforward operation. NASA found that their data was dispersed over many different places. NASA transferred everything to the cloud and built a Node.js enterprise-scale architecture using the technology. They utilized a web API to connect two different settings.


Node.js is being used on the back-end of many large organizations’ applications because of its advantages, including outstanding performance, simple scalability, high extensibility, and improved efficiency. And it is time for you to implement the same in your business.

There are many other technologies you can go to, for instance, there is Golang which is a worthy opponent for Node.js. It is new, with its own advantages to improve development.
