What is Flutter?

Flutter is an open-source UI software development kit created by Google to create applications that work on different operating systems - such as iOS or Android - using one codebase. 

Flutter uses the Dart programming language. It allows developers to create custom widgets that allow them to create cross-platform apps that not only perform well but also look visually appealing. 

History of Flutter

Flutter was first announced at the Dart Developer Summit in 2015 and then officially released as Flutter 1.0 by the end of 2018.

Since then, Flutter has evolved into a mature and widely adopted cross-platform development framework, with regular stable releases introducing performance improvements, new platform capabilities, and tooling enhancements.

A major milestone came with Flutter 2.0 in March 2021, which expanded Flutter beyond mobile to support web and desktop platforms, including Windows, macOS, and Linux. This positioned Flutter as a unified UI toolkit for building applications across six platforms from a single codebase.

Flutter 3.0, released in 2022, further strengthened desktop support, improved performance, and introduced enhancements for emerging device categories such as foldables. It also brought significant updates to developer tooling and productivity.

Since then, Flutter has continued to evolve through frequent releases in 2024–2026, with improvements in rendering performance (including the adoption of the Impeller rendering engine as default on mobile platforms), better web support (including WebAssembly-based builds), and ongoing investments in developer experience and ecosystem stability.

Flutter is actively maintained by Google and supported by a large global community. It is used in production by companies across industries, and its cross-platform capabilities now extend beyond mobile to web, desktop, and embedded devices.

Companies using Flutter

Flutter was initially adopted as a fast and efficient solution for startups and small-scale projects, thanks to its rapid development capabilities and single codebase approach. However, over the years, it has evolved into a mature framework that is now widely used in large-scale, enterprise-grade applications focused on performance and long-term maintainability.

Several high-profile companies and projects have adopted Flutter for app development. Notable examples include:

• Google Ads: Google’s advertising platform uses Flutter for its mobile applications, demonstrating the framework's robust capabilities.
• Google Earth: an example of a truly cross-platform experience with the reach for IOS, Android, and the web - all thanks to Flutter.

What is React Native?

React Native is an open-source framework created by Meta (formerly Facebook) for building cross-platform applications using JavaScript and React. It was first released in 2015 and has since become one of the most widely used technologies for mobile app development.

React Native allows developers to build applications primarily for iOS and Android using a shared codebase, while also supporting additional platforms through its ecosystem. It uses a declarative, component-based approach, enabling developers to create user interfaces that closely match native platform behavior.

History of React Native

Although React Native was officially announced in 2015, its origins date back to an internal Meta (then Facebook) hackathon project around 2013. The goal was to bring the advantages of React – Meta’s JavaScript library for building user interfaces – to mobile app development.

From the beginning, React Native was designed to combine the flexibility of JavaScript with the performance and capabilities of native applications. Over the years, React Native has grown significantly in both adoption and maturity, supported by Meta and a large open-source community.

A major turning point in its evolution has been the introduction of the New Architecture, which includes:

• Fabric renderer
• TurboModules
• JavaScript Interface (JSI)

These changes replace the legacy bridge-based model and enable more efficient communication between JavaScript and native code.

Today, React Native is widely used in production by many companies and has a robust ecosystem of libraries, tools, and resources.

Companies using React Native

React Native has been widely adopted by many top players in the tech industry. The list of the most popular React Native apps includes:

• Facebook: As the creator of React Native, Facebook uses it extensively for its own applications, including Facebook Marketplace and Ads Manager.
• Instagram: As another social media giant owned by Meta, Instagram has integrated React Native into parts of its app to improve developer productivity.
• Airbnb: An early adopter that helped demonstrate React Native's potential (historical example).
• Tesla: The electric vehicle manufacturer uses React Native for its mobile app, allowing seamless interaction between drivers and their cars.
• Walmart: The retail store chain uses React Native to provide a consistent shopping experience across mobile platforms.

Flutter vs. React Native: an in-depth comparison

To compare Flutter and React Native effectively, it’s important to evaluate both technical and business-related factors.

In this section, we analyze the two frameworks across the following key criteria:

• Reusable code base
• Time to market
• Cost of development
• Integration with native SDKs
• Performance
• UI and design system
• Web capabilities
• Maintenance
• Community
• Packages and libraries
• Hiring and building a team

Each of these factors plays an important role in selecting the right technology for your project. Let’s take a closer look at each of them.

Reusable code base

First, let’s talk about the main advantage of both technologies: the ability to share a single codebase across multiple platforms.

Flutter

Flutter enables developers to build applications for mobile (Android and iOS), web, desktop (Windows, macOS, Linux), and embedded devices using a unified codebase. Its widget-based architecture ensures consistent UI and behavior across platforms, as the rendering layer is fully controlled by Flutter itself.

Flutter’s web support has also matured significantly. With the introduction of WebAssembly-based builds and ongoing improvements in rendering performance, Flutter Web is increasingly used for production applications. While there are still platform-specific considerations (such as browser support and performance trade-offs), Flutter continues to move toward its goal of being a truly universal UI toolkit.

React Native

React Native, on the other hand, is primarily focused on building applications for iOS and Android. While it is possible to target web and desktop platforms using tools such as React Native Web or platform-specific extensions, these approaches rely on additional libraries and are not part of the core framework.

In practice, React Native is most commonly used in mobile-first projects, often benefiting teams that already use React for web development.

Key difference

Flutter provides a unified approach to building applications across multiple platforms from a single codebase, while React Native focuses primarily on mobile development with optional extensions for web and desktop.

Time to market

For businesses wanting to survive in highly competitive markets, reducing the time it takes to build the final product is crucial for success.

Flutter

Flutter’s extensive library of preembedded design systems and powerful customization options can significantly reduce development time. Thanks to robust documentation and community support, developers can be sure they get what they need to finish the job quicker.

Additionally, one of the technology's huge advantages is the “hot reload” feature, which makes the development process significantly faster.

React Native

React Native's biggest advantage is the use of JavaScript. The large ecosystem of third-party libraries and components speeds up the development process, and using JavaScript allows users to work with their IDE or text editor of choice.

Additionally, teams familiar with React can often reuse knowledge and parts of the codebase across web and mobile applications, which can further accelerate development.

Key difference

Flutter accelerates development through built-in tools and a unified architecture, while React Native enables faster onboarding and development for teams already experienced with JavaScript and React.

Cost of development

The ability to maintain a single codebase for multiple platforms can lead to significant cost savings in the long run, and both Flutter and React Native offer these capabilities. So what might be the difference in terms of the cost of development?

Flutter

In general, Flutter has always been a technology meant to build apps quickly, which has a great impact on lower development costs. Its performant tooling helps reduce the time spent on testing and debugging, and its free and open-source nature further reduces initial setup costs

Flutter also provides a rich set of pre-designed widgets, which can speed up UI development.

React Native

React Native can offer cost advantages through easier hiring and a large developer pool. Since it uses JavaScript, recruitment can be faster and more accessible. As a more established technology, React Native also has a mature ecosystem, with many well-documented solutions and a large community for support.

Its extensive ecosystem of libraries and third-party plugins can accelerate development by providing ready-made components and integrations.

Key difference

Cross-platform consistency can be one of the main differentiators between these two technologies. React Native relies on native components, so there can be discrepancies in how an app looks and behaves across different platforms (iOS vs. Android), which may require additional platform-specific adjustments.

Flutter offers a more consistent experience across platforms since it renders everything using its own rendering engine and shared codebase.

Integration with native SDKs

Integration with native software development kits is essential for accessing platform-specific features.

Flutter

Flutter provides a rich set of plugins for accessing native features; if a required plugin is not available, developers can write platform-specific code using platform channels that enable communication between Dart and native code.

This flexibility ensures that Flutter apps can leverage the full range of native functionalities.

React Native

React Native benefits from the vast JavaScript ecosystem, but integrating native SDKs often requires connecting JavaScript code with native code (written in languages like Kotlin, Objective-C, or Swift). 

In modern React Native, this is handled through its updated architecture, including mechanisms such as TurboModules and the JavaScript Interface (JSI), which enable more efficient communication between JavaScript and native code.

Key difference

In general, for both Flutter and React Native, you have to write some code in Dart/JavaScript (Flutter) or Kotlin/Swift (React Native), along with a layer of integration code. 

What we would praise is Flutter's clean approach. It is opinionated about how to structure native plugin code and provides tooling to generate parts of the integration layer.

Performance

Flutter

Excellent performance is probably one of the most well-known benefits of Flutter and an area where the technology truly shines. High performance is particularly noticeable in graphics-intensive applications and animations, which is what Flutter’s capabilities are perfect for.

Additionally, Flutter uses its own rendering engine (Impeller), which is now the default on mobile platforms, replacing Skia in most cases. With Impeller, Flutter benefits from improved animation performance, reduced shader compilation issues, and more predictable rendering behavior.

React Native

React Native performance is generally considered good, but it may require more optimization in visually complex applications. 

React Native’s use of native components ensures a fluid user experience, but complex animations and heavy UI interactions can demand additional effort from developers.

Modern React Native uses a new architecture (including Fabric, TurboModules, and JSI), which significantly improves communication between JavaScript and native code compared to the legacy bridge model. However, achieving consistent high performance across platforms may still require additional optimization in complex applications.

Key difference

Flutter provides a more consistent performance model across platforms due to its own rendering engine. React Native relies on native components, which can deliver great results but may require more platform-specific tuning in complex scenarios.

UI and Design System

Creating a visually appealing app is the key to user engagement. 

Flutter

Flutter’s rich set of customizable widgets and its own rendering engine make it easy to achieve pixel-perfect UIs across all platforms. Because Flutter renders all UI elements itself rather than relying on native components, it provides a high level of consistency across platforms.

This approach allows teams to build strong product and brand identities with full control over design. Flutter also enables developers to work at a low level when needed, making it possible to create fully custom views and advanced UI experiences.

React Native

React Native uses native components, which can make achieving a consistent design across platforms more challenging. With the right libraries and tools, developers can still create high-quality UIs, but it may require additional effort compared to Flutter.

At the same time, using native components makes it easier for applications to follow platform-specific design patterns. This means Android apps feel like Android apps, and iOS apps feel like iOS apps, aligning with user expectations on each platform.

Key difference

Flutter offers greater control and consistency in UI design across platforms, while React Native provides a more native look and feel with platform-specific behavior.

Web capabilities

Web support is an important factor when choosing a cross-platform framework, especially for teams looking to extend mobile applications to the browser.

Flutter

Flutter for Web development has improved significantly over the years, offering a good transition from mobile to web. Its web support continues to evolve, with improvements in performance, rendering, and developer tooling.

The flexibility of Flutter's rend ering approach allows for building responsive and interactive web applications. Flutter also supports WebAssembly-based builds, which further enhance performance in certain use cases.

Flutter is particularly well suited for web applications such as dashboards, internal tools, and product interfaces that benefit from a shared codebase with mobile.

React Native

React Native does not support web development as part of its core framework but can be extended to web platforms using solutions such as the "React Native for Web” library. 

The main challenge lies in balancing high-quality web app needs with React Native API compatibility. For web-focused projects, it is generally considered that React.js or other dedicated web frameworks may be a more suitable choice.

Key difference

Flutter provides a more integrated approach to cross-platform development across mobile and web, while React Native relies on ecosystem tools and is primarily focused on mobile applications.

Maintenance

Maintenance is an important factor when evaluating the long-term viability of a cross-platform solution.

Flutter

The single codebase and extensive documentation make Flutter applications relatively easy to maintain. Google’s active development and regular updates contribute to a stable and evolving ecosystem.

Flutter’s structured and declarative coding style also improves readability and maintainability, making it easier to manage large codebases over time.

React Native

React Native’s use of JavaScript and its large developer community make it relatively easy to find solutions and maintain applications.

At the same time, because React Native relies on native components, changes in underlying platforms (such as new OS versions) may require additional adjustments. Managing third-party libraries and keeping dependencies up to date can also be a factor in long-term maintenance.

Key difference

Flutter offers a more controlled and consistent environment for maintenance, while React Native provides flexibility and strong community support but may require more effort in dependency and platform management.

Community

A strong community is vital for providing developers with the support and resources they need. Both Flutter and React Native are open-source technologies supported by large, global communities.

Flutter

Flutter’s community has grown rapidly since its launch, with a wealth of tutorials, libraries, and forums available. Google’s active involvement also ensures ongoing support and continuous development.

As of March 2026, Flutter has over 176k stars on GitHub, reflecting its strong adoption and growing popularity. However, the overall pool of experienced Flutter developers is still smaller compared to the broader JavaScript ecosystem.

React Native

React Native, as a more established technology, has a long history of community support and a mature ecosystem of tools and resources. As of March 2026, React Native has around 126k stars on GitHub.

Its strong connection to the JavaScript and React ecosystem results in a large developer base and extensive community-driven development. The wide range of third-party libraries and solutions makes it easier to find support and address common challenges.

Key difference

Flutter has a fast-growing community with strong backing from Google, while React Native benefits from a larger developer ecosystem built around JavaScript and React.

Packages and libraries

The availability of packages and libraries can significantly enhance development efficiency. 

Flutter

Flutter’s ecosystem of packages and libraries continues to grow, with many high-quality options available. The official Pub.dev repository provides a centralized location for finding and managing packages. 

Flutter’s package ecosystem covers a wide range of functionalities, from UI components to backend integrations (check our list of non-obvious Flutter packages). Additionally, a lot of packages (like Patrol by LeanCode, for example) are officially supported and developed by companies.

React Native

React Native has a well-established ecosystem with a wide range of libraries and components available. Its compatibility with existing JavaScript libraries and tools further strengthens its package ecosystem. 

While the community-driven approach results in a rich collection of third-party libraries, it can sometimes lead to differences in quality and maintenance.

Key difference

Flutter offers a more curated and centralized package ecosystem, while React Native provides a larger and more diverse ecosystem driven by the JavaScript community.

Hiring and building your own team

Finding the right talent is crucial for any development project. Flutter and React Native are very similar in terms of typical usage and general philosophy. 

Flutter

While it might take longer to find Flutter app developers, the growing popularity of Flutter means the pool of skilled developers is increasing rapidly. It is also relatively easy to transition between these technologies, which is a strong point for Flutter. It is also common for native iOS and Android developers to adopt Flutter as part of their skill set, especially in teams transitioning to cross-platform development.

However, it may still be challenging to find senior Flutter developers compared to more established technologies, such as React Native. Training existing team members in Flutter and the Dart language can be a viable strategy for building a competent Flutter team, but it might be easier and faster to look for an established Flutter app development company. 

React Native

React Native benefits from the widespread use of JavaScript and the maturity of the React ecosystem. This makes it relatively easy to find experienced developers and build teams quickly.

Its similarity to React also allows web developers to transition into mobile development more easily, significantly expanding the available talent pool.

Key difference

Flutter has a growing but smaller talent pool, often requiring training or external support, while React Native benefits from a larger and more accessible developer base due to its foundation in JavaScript and React.

Final: React Native vs. Flutter Comparison

Building a mobile application from scratch with Flutter vs. React Native

When building a new mobile application, both Flutter and React Native offer compelling advantages. The choice between the two will largely depend on specific project requirements and priorities, as well as developer expertise

Flutter

Flutter is perfect for projects that require a high degree of customization. The single codebase combined with Flutter’s rich set of widgets can accelerate development and ensure a consistent UI across platforms. 

It’s particularly suited for applications that require complex animations and a high level of visual fidelity. Where high performance is a priority, you can’t go wrong with Flutter. 

Code push solutions are also available for Flutter, for example through tools like Shorebird, which enable delivering updates to applications without full app store releases on supported platforms. You can learn more about it in our recent interview with Eric Seidel, the author of Shorebird and a former head of the Flutter engineering team.

React Native

React Native is a good option for projects that prioritize rapid development and leverage existing JavaScript knowledge. The framework’s mature ecosystem and strong community support can help in building robust applications quickly. It’s an excellent choice for applications that require frequent updates and dynamic content, such as social media apps. However, additional libraries may be needed for more complex UIs.

Replacing an existing mobile application with Flutter vs React Native

Migrating an existing app to a new framework is quite a challenge, as it involves taking several factors into consideration. 

Flutter

For Flutter, the framework’s high performance and customizable UI make it a strong candidate for replacing existing applications that require a modern, responsive interface.

The Flutter Add-to-App feature allows developers to integrate Flutter modules into existing native applications, providing a way to gradually adopt Flutter without a complete rewrite. This approach helps leverage Flutter's UI capabilities while maintaining the existing app's native functionality and architecture

Additionally, Flutter’s ability to replicate intricate designs and smooth animations can enhance the user experience during the migration.

React Native

When it comes to React Native, its ability to integrate with existing native code can facilitate a smooth transition for applications that already use JavaScript - or have modular architectures. 

The large ecosystem of libraries can also help replicate existing functionalities. React Native’s flexible architecture allows for gradual migration, reducing the risk of major disruptions.

How to choose between Flutter and React Native?

Choosing between Flutter and React Native depends on several factors. The most important things to consider are:

1. Specifying your criteria of choice: Identify the key criteria that matter most for your project, such as performance, time to market, cost, and UI requirements.
2. Analyzing your business and IT environment: Consider your existing tech stack, developer expertise, and long-term maintenance capabilities.
3. Preparing the design phase: Structure your project and identify potential frictions, such as integration with existing systems or specific performance requirements.

Let’s examine each of those in more detail so you can make the most informed choice for your business.

Specifying your criteria of choice

When choosing between Flutter and React Native, it is essential to establish clear criteria based on your project needs. Look at the most important factors for your project - is it supposed to handle heavy animations? Will it require high-performance capacities?

For the purpose of specifying requirements, prioritize: 

• Performance requirements: Assess whether your application needs high-performance capabilities, especially for graphics-intensive tasks. For that purpose, Flutter will be the better choice. 
• Development speed: Consider the time-to-market constraints and the availability of developers skilled in Flutter or React Native. If you already have React web developers on your team, getting them to learn React Native might be more efficient than looking for a new team from scratch. 
• UI/UX design: Determine the importance of pixel-perfect UI and complex animations in your application. Flutter beats React Native in that regard, as it’s perfect for visually heavy apps. 
• Cost: Evaluate the development budget, including developer salaries and availability, development time, maintenance, and the ecosystem itself. 

Both technologies will produce the same result—a cross-platform mobile app. However, depending on your priorities, one option might be better than the other, so make sure to evaluate those first. 

Analyzing your business and IT environment

Understanding your current business and IT environment can influence your decision as to which technology you should choose. 

Take a look at your existing tech stack. As we’ve already mentioned, if your team is already proficient in JavaScript and React, building a React Native app might be the better choice. If you’re looking for a fresh start with a greenfield solution, then Flutter is a clear winner. 

You should also consider how well each framework integrates with your existing systems and tools. 

Flutter is generally better for scalability due to its performance advantages. A feature-based Flutter architecture enhances scalability by isolating features into independent modules, allowing for easier maintenance and development.

That said, the extensive React Native ecosystem also makes it highly scalable, especially for teams familiar with JavaScript and React.

Preparing the design phase

Companies like to focus on the development stage itself, but the research and design phase is critical to ensure a smooth development process. 

Remember to plan the project structure and identify the components that will be shared across platforms versus those that need platform-specific implementation. Identify potential frictions such as third-party service integrations, performance bottlenecks, and UI/UX consistency across platforms.

The most important design difference between both technologies is that React Native uses native components, making it easier to achieve a platform-specific look and feel. This is great if your design requires adhering closely to iOS and Android standards. However, it’s important to remember that with this approach, you lack control over the final design, as it’s strictly translated from JavaScript.

Flutter is fantastic when you want something more custom and unique. Its rich set of customizable widgets allows for highly flexible and creative designs and enables a consistent look across platforms.
