What is Node.js?
Node.js is an open-source, cross-platform JavaScript runtime environment that enables Node.js developers to run JavaScript code outside a web browser.
Built on Google Chrome’s V8 JavaScript engine, it supports server-side JavaScript, enabling the development of scalable server- and network-based applications.
The latest version of Node.js, i.e., v25.9.0, released in April 2026, introduced performance optimizations, security hardening, and better alignment with modern web standards.
You can always consult the Node.js official release schedule for the latest LTS (Long-Term Support) and current versions.
What’s good about Node.js is that it allows you to build your web application by using just one programming language, i.e., JavaScript, for both server-side and client-side.

List of 10 Websites and Mobile Apps Built With Node.JS
From industry giants to disruptive startups, Node.js has become the backbone of modern web architecture. Here are 10 world-class websites and mobile applications that leverage Node.js. These companies use it to handle massive traffic. They ensure real-time performance. They also maintain a competitive edge in 2026.
1. Netflix & Node.JS
With over 325 million paid subscribers across 190+ countries as of Q4 2025 and ad revenue hitting 1.5 billion in 2025, Netflix is currently the world’s biggest video streaming platform for movies and television series.
Serving such a staggering number of customer-base with personalized streams is a huge operation that is done by the Node.JS framework. According to Kristofer Baxter’s Netflix Tech Blog post, Node.JS has improved Netflix’s load time by 70%. Netflix developers use TTI (time to interact) metric to measure this improvement. It’s the time taken between app startup and user interaction.
With a huge number of personalized content packages, every push cycle slows app scalability, so Netflix decided to move to a lightweight and fast Node.js. Many other similar apps use Node.JS to build a Netflix-like streaming platform.
If you talk about Netflix’s microservices architecture, Node.js is also an important cog in that wheel, enabling services such as content delivery, user authentication, and a recommendation engine to scale independently. Because of this architecture, Netflix can serve hundreds of millions of simultaneous streams without performance degradation.
2. Uber & Node.JS
With over 40 million trips per day and more than 200 million monthly active users globally, Uber needed a platform to deliver navigation and real-time tracking at a massive scale. That’s where Node.js came into the picture.
Uber saw three core strengths that Node.js could provide:
There are more than 600 stateless endpoints written in Node.js that handle more than 2 million remote procedure calls (RPC) per second in Uber’s API ecosystem. You can read about Uber’s Node.js architecture decisions on their engineering blog.
3. PayPal & Node.JS
PayPal is amongst one of the largest companies that use Node.JS. PayPal has over 400 million active user accounts across 200+ countries, making Paypal one of the most popular websites built using the Node.JS application. Node.JS was used to build the client-side Node.JS web application.
Building their application website using Node.js took only half the time of previous Java-based applications, with 33% fewer lines of code, resulting in 40% fewer files to build the whole Node.js app.
Jeff Harrell, Senior Director of Payments Products and Engineering at PayPal, wrote in the PayPal Engineering blog:
“Node.js helps us solve the boundary between the browser and server by enabling both the browser and server applications to be written in JavaScript. It unifies our engineering specialties into one team, which allows us to understand and react to our users’ needs at any level in the technology stack.”
4. eBay & Node.JS
eBay is amongst some of the famous websites that are powered by Node.JS. With a customer base spanning over 135 million active buyers worldwide, it offers e-commerce trading platform for consumer-to-consumer and business-to-consumer dealings.
eBay was facing needs to make its website more real-time responsive than existing condition. This is where Node JS came in the picture, as it was the only reliable solution that eBay could trust its giant e-commerce traffic with. The beauty in Node.JS application done by eBay is that they followed, Build once, deploy everywhere and automate the rest of the modules. This made eBay one of the greatest Node.JS examples in applications.
Senthil Padmanabhan, Principal Web Engineer at eBay, detailed the approach on the eBay Tech Blog:
“We had two primary requirements for the project. First, make the application as real-time as possible while maintaining live connections to the server. The second was to orchestrate a huge number of eBay-specific services that display information on the page.”
5. GoDaddy & Node.JS
GoDaddy manages more than 84 million domains and has a user base of 20 million+ customers. This makes GoDaddy the world’s largest domain registrar. So, GoDaddy being one of the companies who use Node.JS, gives a great reputation to this platform.
To maintain their position at the peak they need to keep themselves updated. Node.JS gives the ability to release new features with a quality application and easy integration tests. Node.JS made it possible for GoDaddy to handle the same load with just 10% of the previously used hardware.
Antonio Silveira, Vice President at GoDaddy states:
“We are now using about 10x fewer servers to host our customer websites, and we reduced the Time-To-First Byte (TTFB) considerably from ~60ms to something around ~12ms. Performance is a key differentiator when we talk about web applications, including a better position in Google’s search results.”
Due to the Node.JS application, GoDaddy’s servers were drastically cut from 15 to 4, doubling the traffic capacity. The Node.JS app works 10 times faster on client-side.
6. LinkedIn & Node.JS
With more than 1 billion users across 200+ countries, LinkedIn is the world’s largest professional network. It’s available in 26 languages and owned by Microsoft. LinkedIn used Node.JS to improve server-side of their mobile app. Node.JS helped their mobile app to perform 20 times faster with just a fraction of resources used when compared to its predecessor Ruby on Rails.
According to LinkedIn’s Mobile Development Lead, Kiran Prasad:
“One reason was scale. The second, if you look at Node, the thing it’s best at doing is talking to other services.”
LinkedIn is probably the best example to show both, website and app created using Node.JS development.

7. Walmart & Node.JS
Walmart, the world’s largest retailer made its way to online retail market to expand its horizons. They selected Node.JS to build their online retailer app as they believed in the potential that it can achieve. What interested Walmart into Node.JS was it’s asynchronous I/O and it’s single-thread loop model which can handle concurrent requests.
The move to Node.js yielded fruitful results for Walmart during peak traffic periods, such as Black Friday. The platform handled 500 million page views per hour with zero downtime, something the earlier monolithic architecture couldn’t. Moving to Node.js was a huge step for Walmart, putting them on the path to continuous growth.
8. Yahoo & Node.JS
An American technology company offering multiple services likes a search engine, web portal, and many other relatable facets. Yahoo has over 1 billion monthly active users across all its services. Node.JS app changed the whole front-end development culture at Yahoo.
Eric Ferraiuolo, Principal Software Engineer at Yahoo explains:
“You can make it scale, and it is very performant, and every property that we’ve moved over to the Node.js stack has seen an increase in performance.”
Node.js powers many of Yahoo’s features through the Flurry analytics infrastructure and other media services, even after its acquisition by Apollo Global Management.
9. Groupon & Node.JS
Just like eBay, Groupon is one of the sites built with Node.JS. It is a global e-commerce platform where users can connect with private local sellers of goods and services. In June 2015, Groupon migrated from Ruby on Rails to Node.js, resulting in pages loading 50% faster while serving higher traffic.
Adam Geitgey at Groupon mentioned:
“We’re serving the same amount of traffic with less hardware compared to the old stack. Teams can deploy changes to their applications independently. We’ve been able to make a site-wide feature and design changes much more quickly than we would have been able to with our old architecture.”
10. Mozilla & Node.JS
Mozilla is a free software community created by the members of Netscape communication as navigation and web browsing tools supporting over 80+ languages on OS platforms like Windows, Linux, OS X, Firefox OS, etc.
Mark Mayo, Principal Engineer at Mozilla, says:
“We concretely decided to do Node for two reasons: One was the memory footprint, and the second was to be able to use the same language on the server side as well as the client side. It’s super empowering for the whole team.”
Mozilla primarily uses Node.js across its developer tooling ecosystem, including the MDN Web Docs platform, Firefox DevTools, and several internal build systems. Therefore, Mozilla is a prime example of how Node.js not only empowers consumer products but also enhances the developer experience.
