React Native vs Flutter-Which One To Choose?

Developers keep discussing about the trending technology and React Native vs Flutter but now it has become the talk of today’s town. As the demand for application has increased, the pressure has also increased on enterprises, entrepreneurs, and even start-ups to focus more on mobile app development.

At the same time, there has been plenty of new technologies that help both users and service providers to optimize services, based on user demands.

But, this freedom is provided by the app development platforms.

There are various development platforms available for developers to create or build mobile applications, even for cross-platform apps.

In the most popular cross-platform software development React Native and Flutter are at the top with the reference of Statista. Previously developers need to write their individual application programs for both android and iOS mobile apps. Because of these two popular frameworks with the single code writing Apps are making and can run into both Android and iOS mobile platforms. That less coding work code has also impacted on the building cost of overall app making positively.
By using Hybrid App Development frameworks the app making costing is reduced and also the line of codes.
In this article, we are going to talk about which cross-platform is the best one in 2021, and why?
So, to compare React Native and Flutter we have contrasted them according to six important criteria of frameworks:

  • Performance
  • User Interface
  • Development Time
  • Stability
  • Clientele
  • Documentation & Toolkit

React Native, launched in 2015, has been into the limelight for allowing developers to create cross-platform apps for both major platforms such as Android and iOS.

However, the top tech giant Google came following Facebook’s React Native and launched its much-hyped cross-platform framework -Flutter in 2017.

After going through various experimental and improvement process, it has launched the sixth and final version of Flutter Preview 2 which will be followed by the stable version of Flutter 1.0.

Update: Google finally comes up with the much-awaited Flutter 1.0 release. Cheer up for developers who are looking for stable release.

That resulted in tough competition between the two top mobile app frameworks -Flutter and React Native. Now developers are actually puzzled in between two frameworks like which one to choose.

So, we have found out solutions to provide you with the comprehensive ideas of the two platforms so that you can easily find their significance and imply as per your usability.

What is React Native?

React Native was invented by the Facebook, it offers the developers the capability to create cross-platform applications for both Android and iOS device.

It’s a JavaScript Framework that supports real-time Android and iOS applications with a native rendering approach.

React Native came offering an alternative to developers who were struggling to develop apps using Android Studio for Android and XCode for iOS.

What is Flutter?

Flutter is developed by Google and its first preview 1 was released in 2017 and get large user attention across the world. The mobile app SDK offers to create high quality and extremely fast application which can run on both Android and iOS devices.

React native uses JavaScript language to write while Flutter uses Dart for the same. However,flutter has a thin layer of C/C++ code which developers can easily approach and also provides complete control over the system.

Let’s take a look at the quick overview of the two Cross-Platform frameworks React Native Vs Flutter;

Features React Native Flutter
Initial Release It was initially released in 2015 Flutter’s first Preview released in 2017
UI Components Based on Proprietary Widgets Based on Native Components
Language It uses JavaScript Flutter uses Dart language
Speed React Native works Faster It’s a bit slower than React Native
Configuration Setup Provides no streamlined setup and Configuration Flutter offers compact and straightforward Conf. Setup
App Performance Performance is a bit slow due to interaction initiated through JavaScript bridge Extremely fast due to interaction initiation is higher at 60fps animation standard.
Tooling React Native incorporates the bulk of IDESs & tools. Flutter has compatibility with IntelliJ Idea, Visual Code Studio, and Android Studio
Code Structure Code Structure direct with React Native as it uses JavaScript It is messier with Flutter as it has a separation between templates, styling, and data in the file
Stateful Hot Reloading React Native offers hot reloading Flutter also offers hot reloading
Less due to dependency on third-party apps Better due to access to the device’s core functionality
Hardware Specific APIs It has supporting API to specific hardware Flutter too has supportive APIs for specific hardware
Documentation It’s a bit disorganized and clumsy Flutter offers regimented and smooth documentation
Community Has large community support It is new, so it has not so strong community support

Let’s compare React Native vs Flutter based on these below mentioned features
react native vs flutter Comparission Points

1. Performance

Both React Native and Flutter provides the awesome performance to users. But there are some areas where developers may find an edge between the two of them. Some may like React Native while some may choose Flutter to work with. Let get more clear insight through the comparison right here.

React Native:

React native works excellently when you choose to build native apps. You are not going to face any problem regarding its performance. To code in React Native, you first need a bridge that harnesses the Javascript code with the native environment of the device. For that, you simply need an interpreter to harness both JS coding and device environments. But that bridge is an additional object which requires more time in setup of that and also in processing time. Although, you will get standard and reliable performance, without any doubt. But, the issue begins with when you build a hybrid app. You may face a problem with its architecture, libraries, and native components.


Well, as far as Flutter is concerned, you get everything customised right of your choice. Flutter framework requires Dart language in mobile app developments. The main advantage of using Dart is that there are no requirements to create interlayers for accessing the native features of the device. Because of that flutter takes less time to execute code and uses require fewer resources for that. Every app made using this platform are very fast and responsive even takes less time to load complex animations.

My View: Honestly speaking Flutter has the edge over React Native here. But, developers may choose the framework as per their comfort of use or requirement.

2. User Interface

Creating a quality user interface does matter and developers especially eye on the UI feature while selecting the development frameworks.. When it comes to depicting User Interface the designing approach is different for both frameworks. Just go through the comparison given here.

React Native:

When it comes to finding ‘User Interface,’ React Native is based on the native components. It inherits the native visual element and appearance from the device like buttons, navigations, and menus. That inheritance of React Native makes all element looks like native to the user but provides the best experience compared to the native one. Building blocks for user interface become quite easy and Expert React Native Developers may provide the best results using the React Native components.

However, React Native also has one drawback in UI design and that is it will look different in both Android and iOS.


Here’s, developers meet a completely new and different scenario as building blocks and creating an excellent user interface. With Flutter, developers can build quality and fully customised UI designs with additional native support. Flutter has the plus point in user experience because of its consistency. If the source code is upgraded by the developer then and only the User Experience may differ and if not then it will act as familiar. Flutter broadcasts the images on the screen directly using the C++ graphics rendering engine But, it faces some problems while creating UI for iOS and that is the major drawback of Flutter in UI.

My View: Both are good here, but if you have quality demand for iOS UI, then opt for React Native.

3. Development Time

On time delivery of the project, this is what has been promised by every company while taking a project.Yes, there are plenty of frameworks providing cross-platform application but only a few stands by the promise and they are everyone’s favourite React Native and Flutter (Flutter is more reliable than React Native). Also, Flutter and React Native saves time and resources in mobile app development because of their hybrid nature.So, let’s find out which one serves you well as far as development time is concerned.

Entity React Native Flutter
Github stars 89,600 98,900
Github commits 20,774 20,151
User community 19,800 13,700
Stackoverflow Questions 82,954 57,469

React Native:

React Native offers ready-to-use components and you get more exceptional supports as it creates fewer issue and helps developers build a faster landscape of mobile applications.The big reason behind that is its oldness. React Native has so many libraries that help developers to make their lines of code less and easy to make it. However, with the positive side, it also has the negative side those libraries and packages are not updated for a long time and because of that sometimes it results in bugs. React Native has a huge building community and that it is fully dependent on it.


Flutter is released just after two years of React Native but since then it is fully supported and updated by google engineers. Still, flutter has better documentation and a sufficient collection of library codes that are regularly updated by the big G. Just like React Native it does not need to connect with third-party libraries to work correctly. That promises high productivity by the flutter to develop any app in less time. But on the other end, it is still under the development process (as a stable version for Flutter 1.0 yet to be released), it takes a bit longer time to complete your project. It offers better usability, but as far as development time is concerned, it requires more improvement.(Every app build in Flutter are more good in user experience compare to React Native)

My View: Development time is an important factor to look into. However, if you have projects which are abided by any time-bound, you are free to choose any platform you want. However, if you have to finish the project within the time-frame, then will suggest working with React Native.

4. Stability

Stability is one of the biggest things to look into when it comes to choosing the right frameworks. Being a trusted mobile app development company, you need to opt for such frameworks that offer improved stability. When it comes to the listing of the more stable performance of app that directly points towards their frameworks. React Native and Flutter provides the best stability across many other cross-platform frameworks also they are made by reputed companies like Facebook and Google and more important is they are open-source.

React Native:

React native old and trusted framework which is supported by a large community and therefore very famous among developers. It is stable since its launch and helps developers to provide stable cross-platform apps quickly.But still, it requires additional attachments for iOS and Android individually and it is also dependant on native elements of the device. Also, when a new firmware update comes it becomes really hard to make changes. Because of Android 10.0 and iOS 13.6, even the Reacts latest updates apps are facing some small bug problems or the entire app is crashing. In the remedies of that, developers made many changes in OS updates and focused more on QA testing of apps in-depth and updating apps respectably. Every developer should be updated with these kinds of updates. This drawback is a kind of compromise for getting the efficient performance of the native behave of this framework.


Flutter is new and available in beta version only. When the device gets new OS updates that time flutter shows it’s resistant behavior towards changes. Flutter has it’s own QA testing tool while React Native does not have any. Therefore, developers need to wait untill the tech giant launches the stable version ‘Flutter 1.0. However, the recently released Flutter Preview 2 offers more tools to developers.

My View: To me React Native steals the show here due to its maturity in the industry.

5. Clientele

Having a large number of clients entirely depends on quality service, reliability and stability. So, you need to find which one from the two -React Native and Flutter surpasses the criteria.

React Native:

React Native is new and has been in the market for a long time. So, there is no doubt that it has the edge over Flutter. There are some big brands that are the most trusted clients to React Native which include, Skype, Facebook, Tesla, Airbnb, Instagram, Walmart, etc.


As far as Clientele of Flutter is concerned,  it has some valuable clients such as Alibaba, Nubank, Live Quiz and much more4. These websites are not entirely dependent on Flutter, but they have started using it gradually. Besides, as the technology is new, the Flutter also trying with all its means to make its presence felt in the market and tech industry.

My View: Again React Native rules roost due to the advanced maturity level.

6. Documentation & Toolkit

Frameworks with quality documentation and toolkits are impressive. Let’s check out gets more score out of the two here. It developers to know the right structure, architecture, find the code easily.

React Native:

React Native has documentation, but it’s a bit disorganised and clumsy. So, developers have to put in a bit of extra effort to look for the new architecture.


While Flutter has more organised documentation and offers extensive IDE which is the best option for developers to get things done in fewer efforts.

My View: Here Flutter wins the Race.

Market Trends & Further Technology Development:

After February 2020 the search volume of flutter is increased compared to React Native that is showed in the below image:

React vs React Native

The world is changing rapidly in this modern tech era. As soon as you come to the market more reputation you can get. React Native came into the market two years before flutter launched and that is the biggest reason for it in developers and market manipulation. Even if flutter launched two after react-native currently it is still breaking the market value of React Native and that time is near when flutter will take over the leadership of the whole cross-platform market.

In 2019, the Google team demonstrated the beta version of Flutter in the I/O event that supports web applications and mobile applications. Now, flutter’s portability feature is under development but after the work is done it is going to change the cross-platform development market.

Both React native and Flutter holds some exceptional quality in respective fields. But, while going through the topic, one can say that React Native is a bit friendly than Flutter because of the availability of developers in the current market scenario. Flutter is better in performance, User Interface designing, Stability, and for better future developments.

To clear more doubts like what to choose and what not for that we have created a small survey. So, let’s check it:

Entities React Native Flutter
Performance Good Best
User Experience Good Best
Development Time Good Best
Stability Good Best
Making Charges Best Good
Market Trends & Further Technologies Good Best

The results are clear after reading this whole blog we can say that flutter will have a brighter result in the nearest future but the importance of React Native will not be going to remove.
