The Most Popular 10 React Apps Used by Massive Websites

Staying up-to-date with the latest trends in the ever-evolving digital landscape can be a daunting task. Nevertheless, leading players in the industry are managing to maintain their competitive edge. Amidst the perpetual change online, one trend that has come to the fore is the development of React applications using ReactJS. This state-of-the-art technology is instrumental in creating user interfaces that are not only intuitive but also highly responsive.

It’s impossible to ignore the immense potential of ReactJS. With an increasing number of resources capitalizing on its benefits, ReactJS has emerged as a favoured choice among developers. One of the best demonstrations of this popularity is the ReactJS framework, which we will delve into in this article, discussing its best applications.

For those curious, big names are on the horizon.

What is the definition of ReactJS?

ReactJS is a comprehensive JavaScript library that is specifically geared towards designing user interfaces. ReactJS enables developers to create intricate web applications without the need for users to frequently refresh the page, as data is updated in real-time. Its primary objectives are simplicity, speed, and scalability, which makes ReactJS a fast and straightforward way to run programs on a personal computer. Additionally, ReactJS is capable of processing the user interface for applications since it is a JavaScript runtime.

What leads businesses to employ React Native applications?

As they seek to build cross-platform applications, businesses are increasingly opting to employ React Native in order to streamline the process. React Native offers significant benefits, such as the ability to reuse much of the codebase without additional effort. As a result, businesses can launch their apps to customers with far greater speed and minimal delay. Additionally, React Native boasts superior adaptability and offers a simplified user experience, making it an optimal choice for developing next generation mobile applications across various platforms.

React framework is the backbone of internet giants


As the bedrock of its website, Facebook relies on ReactJS to allow the application code to function efficiently. The mobile app, on the other hand, is built using React Native, a framework developed on top of ReactJS. React Native is responsible for presenting native iOS and Android components rather than relying on Document Object Model (DOM) elements.

It is worth highlighting that Facebook is the originator of the ReactJS library, which is why it is logical for the platform’s app to integrate this library. Facebook has recently debuted a beta version of React Fibre, which involves rewriting the ReactJS library.


Netflix has also relied on ReactJS, notably on the Gibbon platform. This platform was created to replace the web browser’s Document Object Model (DOM) for low-performance television sets. According to a blog post from the streaming service, ReactJS has yielded favourable results for Netflix, including improvements in startup time, runtime efficiency, modularity, and more.


PayPal has incorporated ReactJS into its payment system to enhance the user experience for mobile device users. The inclusion of ReactJS enables customers to access the payment system while on the move, providing greater convenience and flexibility.

PayPal relies on two core code bases: the PayPal payment button in a website app and the companion script PayPalExpressCheckOut.js.


The React framework was employed in building Reddit, an immensely popular social news website. Users can submit content on any given topic, with other users reacting via upvotes or downvotes, as well as engaging in further discussion or debate on the issue, depending on its level of popularity.

If you are seeking a platform that offers React support, Reddit is an ideal option. Reddit utilises the ReactJS program, which enables users to rapidly create content and facilitates its sharing.


In constructing its Facebook-based user interfaces, WhatsApp utilises Underscore.js and Velocity in combination with ReactJS.

The WhatsApp Web app has recently integrated React, following in the footsteps of the Facebook online experience mentioned earlier. Learn more about how to organise a React app using atomic design principles in our blog post here.


ReactJS is utilised by Instagram to power many of its features and functions, including integration with Google Maps APIs and geolocation services, precise search capabilities, and the ability to source tags without relying on hashtags. The API supporting these components is impressive, delivering an unparalleled level of functionality.

Instagram is an entirely React-based application, offering its users access to all of its incredible features.


Dropbox, a well-established platform, initially leveraged ReactJS to take advantage of its benefits, including reduced file sizes and faster refresh rates. These features led to improved usability for users.

Several companies, including Dropbox, have adopted ReactJS due to the online data backup options and cloud storage it offers.


Discord is a social networking platform that allows gamers to share in-game media such as images and videos. React applications enable users to access a range of features and functions, with an impressive 98% of Discord’s code being based on the ReactJS framework. This facilitates a more engaging player-to-player communication experience while gaming across various applications. The React framework also ensures that the application is highly responsive and easy to use on any mobile device, regardless of the operating system (Android or iOS).


ReactJS technology has been implemented throughout Airbnb’s website to improve the user experience, particularly in regards to search and chat functionalities. The research team at Airbnb tasked sixty developers with building the company’s React-based application, after which these developers adapted the ReactJS code for use with other applications.


Pinterest is an innovative social media and content curation platform built on the React-based image-sharing website and accompanying application. This platform enables users to view any type of media, including GIFs, pictures, and videos, that they have saved to their personal pinboards. React is the programming language that powers this application, making all of these features possible.


In today’s market, companies are tasked with delivering top-tier applications for their customers. Consequently, many large organisations have started to develop React applications or integrate React into their existing software. This is due to the numerous advantages that React offers, which justify the time and resources required to update the framework. Ultimately, React applications deliver an exceptional user experience, making investing in React a wise business decision.
