To help you make an informed decision, here’s a quick preview of what we’ll cover in this blog.
We first take a step back and quickly understand how we got here. In the early days of mobile app development, building an app meant developing separate versions for iOS and Android, using different programming languages like Objective-C and Java. This process is known as native app development, It requires writing and maintaining two entirely different codebases.
Enter cross-platform frameworks. They altered the game since they allow developers to write one codebase for both iOS and Android platforms. Little wonder then, by 2023, almost 50% of mobile apps were being developed using cross-platform frameworks such as Flutter and React Native.
The most popular frameworks found in today’s ecosystem are Flutter, launched by Google in 2018, and React Native, introduced by Facebook in 2015, both frameworks have high adoption levels in the development world, each one with its unique strengths.
This guide will take you through the core difference between Flutter and React Native so you’re able to identify which one is best suited for your app project. By the end of it, you will be much clearer about which one will get you to market, deliver a seamless user experience, and keep your costs in check.
React Native is a free and open-source platform by Facebook that allows developers to build mobile applications using JavaScript. You can use React Native to build Android and iOS apps from one single codebase. Once developed, these apps can be published on the Google Play Store and Apple App Store with ease.
Flutter is the open-source framework by Google for building cross-platform applications on mobile, web, and desktop. Flutter is especially praised for its rich set of pre-built widgets and flexible design capabilities, enabling the creation of highly customizable and responsive UIs.
Before we dive into the full details, let’s briefly talk about key aspects that will help you choose between Flutter and React Native for your app development project.

Hire ExpertReact Native vs Flutter popularity is no secret, and if you’re looking to develop an app, understanding the key differences between these two frameworks is a must. While both Flutter and React Native support cross-platform app development, they cater to different needs depending on your app’s complexity. For example, if your app requires AI-based functionalities, Flutter might be a better choice. If you’re looking for a more native feel or have a team with strong JavaScript expertise, React Native could be a better fit.
A very important consideration in choosing a framework is how easy it is to learn, especially if you are building a development team or deciding which technology to adopt.
React Native uses JavaScript, the most widely used programming language. This may seem like an advantage, but JavaScript is known to have quirks and complexities that can make it challenging for some developers, especially those who are new to it. You might have to deal with classes within classes and other irritating syntaxes, that will complicate coding and slow down production.
Flutter uses the language Dart, which Google developed. Dart is known as a much more intuitive language regarding easier learning, especially for developers who have experience in native mobile development, since it is close to Java and Kotlin. Due to its simplicity, it appeals to many developers as easier and pleasing to work with, which may lead to faster and more productive app development.
Although both Flutter and React Native are cross-platform development-friendly, they differ slightly in the scope of platforms they support.
React Native is used to develop apps for iOS, Android, and the web (via React). Recently, it has also expanded to desktop apps for Windows and macOS, making it a versatile tool for cross-platform development.
Flutter then takes the cake by supporting not only iOS and Android but also macOS, Windows, Linux, and embedded systems (like infotainment systems in cars). The simplicity of using one codebase across these platforms with Flutter 3 is a very attractive prospect for a business looking to reach as many people as possible on as many platforms as possible.
It is important to have access to a wide array of packages and libraries for building feature-rich apps efficiently.
React Native has a much larger ecosystem because of NPM, the Node Package Manager, and it already hosts over 1.8 million packages. Although this gives any developer access to a huge range of tools and libraries, most of them were designed for web development, so they are not optimized for mobile apps. You need to research your third-party packages very carefully to make sure they will be suitable for production.
Flutter, though younger, gathers speed rapidly. Pub.dev is the repository of Flutter, which is expanding rapidly, and packages are mostly of higher quality because they suit the use of Flutter-specific apps. In 2023, the number of Flutter repositories counted almost doubled as evidence of its fast-growing application and maturity.
Good documentation can be a lifesaver, particularly when developers start using a new framework for the first time.
The documentation of Flutter is said to be more comprehensive and much better organized than React Native. It has detailed developer guides whether you are coming from a native technical background or whether you come from web development.
React Native is less structured in comparison to others. Even though it covers the basics, more comprehensive resources can be hard to find and require support through community-driven services such as Stack Overflow or even a direct search on Reddit.
Performance is one of the critical aspects that can affect the success of an app, especially for complex, feature-rich applications. When comparing Flutter vs React Native performance, it’s important to note that Flutter often has the edge due to its direct compilation to native code, while React Native relies on a JavaScript bridge, which can introduce some latency.
React Native uses a JavaScript bridge between JavaScript and native components. This additional layer slows down the performance considerably with respect to complicated features that entail anything from sensors to Bluetooth being device-specific.
Flutter doesn’t rely on such a bridge. It directly compiles into native code, which makes it faster and better in most scenarios. Flutter has also shifted over to a new rendering engine called Impeller recently, optimizing the GPU usage of animations and frame rates. That gives Flutter a noticeable performance lead in handling visually demanding applications.

Your development environment setup experience as a developer is greatly influenced by how easy or difficult it is for you to set it up.
Flutter comes with a built-in command-line interface (CLI) that includes a tool called Flutter Doctor. This tool checks the local machine for all the necessary tools and configurations needed for development, making the setup process much smoother. Flutter Doctor guides you through setting up your development environment, whether you’re targeting iOS or Android.
React Native comes with a CLI, but during the setup process, it doesn’t quite give you as much detail. On the other hand, React Native has a tool called Expo where development becomes pretty straightforward by providing services and libraries in order to have everything accomplished. You can preview your app directly on your phone through Expo instead of using Android Studio or XCode, thereby making the whole development process much faster.
Debugging forms an integral part of development, and both frameworks offer you the tools to identify and solve the problems within your apps.
Debugging within React Native can prove a little tricky at times, especially when errors occur within the native components. However, React Native has released Flipper, a debugging tool that aids you in managing any errors in both your JavaScript code as well as your native code and makes the process a little less daunting.
Flutter has a much smoother debugging process. For example, Flutter has something called DevTools, which is actually integrated right into Android Studio and Visual Studio. Moreover, in Flutter, developers can see the UI and why elements appear this way, so they can easily debug visual issues.
Both frameworks provide a feature named Hot Reload that enables the developer to view all changes in real time without rebuilding the whole app.
The most significant highlight of Flutter is Hot Reload. This gives developers an instant view of changes and lets them tweak things without requiring them to restart the app. This really speeds up development and debugging.
React Native serves a similar purpose, allowing real-time updating during development. Although both frameworks offer this functionality, it feels as though Flutter’s edition has been more reliable and fast for more complex changes.
IDE (Integrated Development Environment) support can make all the difference in productivity while developing.
Flutter is supported by a vast number of IDEs like Android Studio and Visual Studio. It is easier to work in Flutter for developers who have worked on native development for Android previously because they already have experience with Android Studio.
React Native can be developed in Visual Studio, WebStorm, or even Notepad, but preferably in Expo because the setup and the development are so quick.
The size and activity of a framework’s community are key factors influencing the likelihood of solving problems quickly or finding help in time.
React Native began in 2015, so it is an ancient library with a very large, vibrant community behind it. This implies you are sure to find libraries, third-party tutorials, and online help abundantly.
Although Flutter is a more recent framework, it gains momentum very fast. The framework is backed by Google, so there is assured long-term support and enhancements. In GitHub activity, the community of Flutter closes issues and fixes bugs much faster than React Native, which makes it a reasonable pick for developers who would prefer the latest fixes and updates in a timely manner.
Reusing code helps reduce development time, overall cost, and the possibility of bugs and errors.
Flutter takes the reusability of codes to a completely new dimension with the thorough use of widgets. Widgets in Flutter are reusable building blocks used to build UI components in such a way that they will look and feel consistent across platforms. This gives Flutter an efficiency and consistency advantage because developers can reuse code without ever thinking about how it would look on other devices.
When it comes to code reuse, React Native allows this as well. But in terms of consistency, Flutter beats that of React Native. This means that the React Native UI widgets rely on native elements. Therefore, at some point, an app developed using React Native may not look exactly similar on the Android platform as it would be on iOS. However, it has vast and matured third-party libraries which gives the maximum flexibility to developers when building platform-specific features.
The biggest challenge in building a cross-platform application is that the UI may not be so consistent on Android and iOS. Consistency is an important design requirement because consistency will always make it seamless for users to move around, irrespective of whether they are on Android or iOS.
Flutter excels in UI consistency because it doesn’t rely on platform-native UI components. Instead, Flutter provides developers with Material Design (for Android) and Cupertino (for iOS) widgets, which mimic the native look and feel of each platform. This means that Flutter apps look almost identical on both Android and iOS, providing a consistent user experience.
On the contrary, React Native employs native components to draw its UI, which could sometimes create inconsistent rendering between platforms. While this approach allows React Native apps to feel more “native” on each platform, it can create challenges when trying to achieve a unified look across Android and iOS.

Probably, the main benefit of cross-platform application development is that it allows businesses to come into the market with quicker applications.
Flutter is all about fast-developing cycles. The framework has already integrated its widgets and big libraries, so it allows developers to make even more applications than React Native in a relatively short period of time. Additionally, Flutter comes with Hot Reload technology that allows developers to see the results of their code changes live and, therefore, speeds up the development cycle.
React Native also offers Fast Refresh, a similar feature to Flutter’s Hot Reload. However, because React Native relies on native components and third-party libraries, there may be more hurdles to overcome, which can slow down development. That said, if your development team is already experienced with JavaScript, React Native’s time-to-market could still be competitive.
Both Flutter and React Native offer cost-effective solutions for businesses looking to develop apps for multiple platforms. The overall development cost depends on expertise and the location of your development team.
Having highly skilled developers with expertise in these frameworks can streamline the development process, ensuring efficient and high-quality outcomes. However, these developers may be on the pricier side of the equation.
Similarly, location is the other side of the coin. For instance, if you’re building a cross-platform on-demand application, like a food delivery app in Dubai, the cost may be lower compared to hiring a team of developers in the US.
Developers who specialize in Flutter are a little more expensive also due to the newer technology that underlies the framework and the smaller supply of programmers who write code in Dart. However, Flutter’s shorter cycles of development and entirely reusable code manage to offset these higher up-front costs.
React Native benefits from a larger pool of developers, thanks to its use of JavaScript—the most popular programming language in the world. If your team is already familiar with JavaScript, React Native may be the more cost-effective choice. On the other hand, if you need to hire specialized React Native developers, costs could be comparable to Flutter.
