When it comes to building scalable and high-performing web and mobile applications, React.js and React Native are two of the most popular frameworks people turn to.
Choosing between these two options is super important for those responsible for making final decisions, as it will significantly impact the performance, user experience, and overall development cost of your service or product.
Whether you want to create an interactive web platform or a high-performing mobile app, understanding the key differences between React.js and React Native will help you make an informed decision for your project.
This guide reveals all about their unique features, benefits, and how they compare to each other. So, without further ado, let’s learn more about both technologies.
What is React.js?
React.js, often just called React, is an open-source JavaScript library created by Meta (formerly known as Facebook) for building user interfaces, primarily for web applications. This technology is the second most used framework in the community, with 39.5% of users worldwide (recorded as of 2024).
Key features of React.js:
- Virtual DOM: Its virtual DOM optimizes rendering, ensuring faster updates.
- Component-Based Architecture: This allows you to develop reusable UI components, thus making it easier to manage and scale applications.
- Declarative Syntax: Its declarative approach simplifies the process of creating dynamic UIs by describing how the UI should look at any given state.
- JSX Syntax: Allows you to write HTML-like code in JavaScript, making it easier to define UI elements directly within JavaScript code.
- Unidirectional Data Flow: Ensures data flows in a single direction, improving code maintainability and debugging.
- Ecosystem Support: Extensive ecosystem of tools, libraries, and community resources to enhance functionality.
What is React Native?
Developed by Meta, React Native is a framework based on React.js principles. It is specifically designed for building cross-platform mobile apps - iOS and Android – and provides a closer-to-native app experience.
With over 20,000 apps and 60 billion downloads, React Native holds a significant 6.81% market share, powering popular apps like Instagram, Messenger, and Netflix.
Key Features of React Native:
- Cross-Platform Development: Write code once and deploy it on both iOS and Android, thus reducing development time and costs.
- Native Components: Renders using actual native components, providing performance close to native apps.
- Live & Hot Reloading: Allows you to instantly see changes without restarting the app, thus improving productivity.
- JavaScript-Based: By utilizing JavaScript, it empowers your development teams to efficiently build and maintain both iOS and Android apps.
- Rich Ecosystem: Benefit from a large number of libraries and community contributions.
- Third-Party Plugin Support: Supports third-party plugins to extend functionality, including access to native device features like the camera and GPS.
React.js vs React Native: A Detailed Comparison
To help you decide which technology is right for your project, refer to this detailed comparison of React.js and React Native across key areas:
1. Development Approach
React.js
- It focuses on building dynamic web applications that run in the browser.
- React.js uses JavaScript, HTML, and CSS to create interactive UIs.
- This technology is ideal for developing single-page applications (SPAs) or complex web platforms.
- According to State of Frontend’s survey report 2024, 69.9% of developers used React.js to develop modern web applications.This makes it a key technology for business owners and founders to consider when planning their digital products.

React Native
- Designed for mobile app development, React Native allows your development team to write code that works on both iOS and Android.
- It uses JavaScript and JSX to create native apps, rendering them into native codes for optimal performance.
- It’s a cross-platform solution, meaning you can write code once and deploy it anywhere, thus saving your development time and resources.
2. Performance
React.js
- It uses Virtual DOM to efficiently update only the necessary parts of your website. This means your app can handle complex interactions and data changes without slowing down.
- React's speed and efficiency make it ideal for crafting websites that constantly change and adapt, such as e-commerce stores with real-time inventory updates or social media platforms with live feeds.
- If you are building complex web applications like dashboards or social media platforms, choose React.js for delivering fast, smooth experiences.

React Native
- As mentioned before, React Native provides near-native performance for mobile apps by utilizing native components (iOS or Android).
- While this cross-platform framework is fast, it doesn’t fully match the speed of native apps built with Swift (iOS) or Kotlin (Android), especially for complex apps.
- However, for most business apps, like e-commerce and social networks, it provides unmatched performance and a seamless user experience.
3. User Interface and UX
React.js
- Thanks to its modular component system, you can create interactive, responsive web UIs that will work across browsers.
- React.js works seamlessly with popular design libraries like Material-UI and Bootstrap. This means you can quickly add stylish and professional-looking components to your app, without starting things from scratch.React.js is best suited for web apps where flexibility and a fast user experience are crucial.
- With React’s wide support for styling frameworks, businesses can create customizable and scalable designs without extra effort.
React Native
- Its native mobile UI components ensure that your app looks and feels like a native app on iOS and Android.
- It does provide some unique UI elements, but you may have to adjust designs according to different screen sizes and resolutions.
- You get a consistent user experience across mobile devices. This makes it an excellent choice for apps that require seamless navigation and responsive design.
4. Community and Ecosystem
React.js
- React's thriving community and ecosystem provide your team access to a wealth of third-party libraries and frameworks, which contributes to accelerated development time and ensures enhanced application capabilities.
- Your development team can use a range of libraries for everything - from data handling to UI elements.
- With regular updates, strong community contributions, and comprehensive documentation, you can rely on this technology for long-term support.
React Native
- While React Native’s ecosystem isn’t as large as React.js, it still includes a broad range of mobile-specific libraries and tools.
- More mobile-specific resources are being added continuously, which means you can easily build fast, high-performing mobile apps.
5. Cost and Resource Management
React.js
- Since it’s used primarily for web development, you will require less initial investment.
- Your development team can quickly transition to React.js, thus reducing training and hiring costs.
- React's component-based architecture and extensive library support streamline the development process, leading to faster time-to-market and lower maintenance costs. This makes it an economical solution for building web applications.
React Native
- Building React Native apps requires developers with expertise in mobile platforms, which may lead to higher hiring costs compared to web developers.
- However, its ability to share a single codebase across iOS and Android platforms can significantly reduce your development time and costs.
- It also reduces the need for separate teams for each platform. If you want to cut down on mobile development costs, React Native is the clear winner.
