React Native vs Flutter: Which to Pick for Your MVP

React Native vs Flutter is usually settled by one question: which language your team already writes. Both ship a single codebase to iOS and Android, both are fast enough for the apps founders actually build, and both get you into the App Store and Google Play. React Native is JavaScript and React. Flutter is Dart.

This guide is for founders choosing a mobile stack for a first app, and for teams who inherited one and want to know what they signed up for. It covers how the two differ underneath, which is easier to hire for, what a mobile build costs to run, how quickly you can fix a bug after launch, and the store rules that catch first-time publishers. If the backend and database are still open questions, our framework for choosing an MVP stack covers those layers.

Key takeaways

• React Native renders with the platform's own UI components. Flutter draws every pixel itself. That one difference explains most of the others.
• Hiring decides it for most startups. A competent React developer can maintain a React Native app. Flutter needs someone who writes Dart.
• Both are current and actively funded. The New Architecture has been the React Native default since version 0.76, and Impeller has been Flutter's default renderer on iOS and on Android API 29+ since the 3.27 release.
• React Native with Expo can push JavaScript and asset fixes over the air between store releases. Flutter compiles to machine code, so the same fix means a new build and another review.
• Store accounts cost the same either way: $99 a year for Apple, and a new personal Google Play account must run a closed test with 12 testers for 14 continuous days before it can publish.

React Native vs Flutter: the short version

Both give you one codebase, two apps and a fast edit-and-reload loop. They differ in the language you write, how the screen is drawn, and what happens after launch.

What to compare	React Native	Flutter
Language	JavaScript or TypeScript	Dart
How the UI is drawn	Real platform components	Flutter paints its own widgets
Hiring pool	Any React developer	Dart developers, a narrower pool
Fixes without a store release	Yes, for JavaScript and assets	No first-party option
Beyond phones	Mobile first, web possible	Mobile, web, desktop, embedded
Backed by	Meta, with Expo as the toolkit	Google

Read the hiring row first. Framework arguments end in a week. A vacant role lasts months.

How do React Native and Flutter actually differ?

They differ in one place that matters: what is on the screen. React Native asks the operating system for its own buttons, lists and text fields. Flutter ships a renderer inside your app and paints its own.

React Native: JavaScript driving native views

Your code is React, written in JavaScript or TypeScript, and the components it renders become real iOS and Android views. A list is a platform list, so scrolling, accessibility and the system keyboard behave the way the platform does without extra work.

The historic cost was the bridge between JavaScript and native code, which serialised every message across it. React Native's New Architecture replaced that bridge with a direct interface between the two sides, and it has been the default in new projects since version 0.76. That removes the class of stutter older comparison articles still complain about.

Almost nobody starts a bare React Native project now. Expo is the standard toolkit on top of it: project setup, maintained native modules for camera, notifications and biometrics, cloud builds for both platforms, and updates you can ship without a store release.

Flutter: Dart and its own renderer

Flutter apps are written in Dart and compiled ahead of time to native code. The widgets belong to Flutter rather than the platform, so a screen can look identical on a four-year-old Android phone and a new iPhone, down to the pixel.

That control is the reason to pick it. Flutter's Impeller renderer compiles shaders when the engine is built instead of while the app is running, and it has been the default on iOS and on Android API 29 and above since the 3.27 release. On iOS it is now the only renderer.

The trade-off is that platform behaviour is something Flutter imitates rather than inherits. When Apple changes how a control feels, a React Native app often picks it up on the next rebuild. A Flutter app picks it up when the framework ships a matching widget.

Which one is easier to hire for?

React Native, for most startups, because you are hiring from the React pool rather than the Dart pool. A developer who has shipped React web apps is useful in a React Native codebase within a couple of weeks: same components, same state management, mostly the same tooling.

Flutter developers are not rare, but they are a separate specialism. If your web app is React and your mobile app is Flutter, you are staffing two ecosystems, reviewing two languages, and writing the same validation rules twice.

The useful question is not which framework is better but which one you can replace. If the one person who knows the codebase leaves in month eight, how long until someone else is productive in it? Answer that honestly and the decision usually makes itself.

What does a mobile app cost to run?

The frameworks are free. The recurring costs are store accounts, build infrastructure and whatever the app talks to on the server.

An Apple Developer Program membership is $99 a year, and you cannot publish to the App Store without one. A Google Play developer account has a one-time registration fee. Put both in the company's name rather than a contractor's, and start them early, because identity verification takes longer than founders expect.

Building for iOS needs macOS somewhere. Either a team member has a Mac, or you rent one from a hosted build service, which both ecosystems support. Everything else (the backend, the database, push notifications, analytics) costs the same whichever framework draws the screens, and our breakdown of what an MVP costs to build covers how scope and team shape the rest of the number.

How fast can you fix a bug after launch?

This is where the two genuinely separate. A React Native app that includes the expo-updates library can send a new JavaScript bundle straight to installed apps. A Flutter app cannot, because the Dart is compiled into the binary.

EAS Update is the first-party service for this. Copy changes, styling, layout fixes and JavaScript bug fixes go out between store submissions:

eas update --channel production --message "Fix checkout button alignment"

The limits are set out in the same documentation. Anything that touches native code, native dependencies, app permissions or the Expo SDK version still needs a new binary and a new review. Over-the-air updates cover typos and logic bugs, not a new camera feature.

For Flutter, every fix is a new build through the stores. Third-party code-push services exist, and they are a vendor and a cost rather than part of the platform. If your product is at the stage where you correct something most weeks, that difference matters more than any rendering benchmark.

What do the app stores require before you can launch?

More than first-time publishers plan for, and the requirements are identical whichever framework you chose. Open both developer accounts in week one of the project, not the week before launch.

Google Play adds a step that catches people out. Under Google Play's testing requirements, a personal developer account created after 13 November 2023 has to run a closed test with at least 12 testers opted in continuously for 14 days before it can apply for production access. Organisation accounts are not subject to that rule, which is one practical reason to register as a company.

Plan the 14-day window into the launch date. Recruiting twelve real people who keep the app installed takes longer than building the screen they are testing.

When should you choose Flutter instead of React Native?

When the interface is the product, or when the same app has to run well beyond phones. The table below is the decision in one screen.

Your situation	Better fit	Why
Your web app is already React or TypeScript	React Native	One language across web and mobile, one hiring pool
Animation-led UI that must look identical everywhere	Flutter	It draws its own widgets instead of borrowing the platform's
The same product on mobile, web and desktop	Flutter	One codebase targets all of them
Frequent small fixes in the first months after launch	React Native	JavaScript changes ship without a store release
A team that already writes Dart	Flutter	The stack you can staff beats the stack you prefer

Three of those five rows are about people rather than technology. That is roughly the right ratio.

What if your app started in an AI builder?

Then the choice may already be made. Bolt sets up mobile projects with Expo, which means React Native underneath, and Replit can produce mobile projects too. Our comparison of how the main AI app builders differ covers which one handles mobile and what each leaves for you to finish.

Whatever generated the first version, treat it as a draft. Store submission, permissions, crash reporting and the access rules behind the screens are the parts that decide whether the app survives real users.

Common mistakes

• Choosing on benchmarks. Both render a list smoothly. Neither framework is what makes an app feel slow; an unindexed query and a 4 MB image are.
• Starting a mobile product as a web project. Converting later is a rebuild, not a setting.
• Forgetting the Mac. iOS builds need macOS, whether it sits on a desk or in a build service.
• Leaving store accounts until the end. Verification, the Play testing window and a first review can add two weeks on their own.
• Running two ecosystems. React on the web and Flutter on mobile means two languages, two sets of review habits and the same rules written twice.
• Shipping without crash reporting. You cannot read a user's console on a phone. Without reports, you learn about crashes from one-star reviews.

Frequently asked questions

Is Flutter faster than React Native?

Not in a way users notice in a typical app. Flutter has an edge in dense animation because it controls the whole rendering pipeline, and React Native's New Architecture closed most of the gap for ordinary screens. Startup time, image sizes and slow network calls affect perceived speed far more than the framework does.

Can one developer maintain both iOS and Android?

Yes, and that is the main reason cross-platform is the default for early teams. Expect a share of the work to stay platform-specific: push notification setup, permissions, deep links and store listings are done twice. Budget time for that rather than assuming one codebase means one of everything.

Do I need a Mac to build an iOS app?

You need macOS somewhere in the pipeline, but it does not have to be your laptop. Hosted build services compile and sign iOS binaries in the cloud for both frameworks, which is usually cheaper than buying a Mac for one project. You will still want a real iPhone for testing.

Can we switch from one to the other later?

Only by rewriting the app. Screens, navigation and state management share nothing between Dart and JavaScript. What does survive is everything behind the API, which is a good argument for keeping business rules on the server instead of in the app.

Pick the stack you can keep staffed

Start from the team, not the framework. If your developers write React or TypeScript, React Native keeps one language across web and mobile and keeps the hiring pool wide. If the interface is elaborate, has to look identical everywhere, or the same product needs to run on desktop as well, Flutter earns the second ecosystem. Open both store accounts in week one either way, and put the Google Play testing window in the launch plan.

If you would rather hand the build to engineers who have shipped to both stores, here is how we build cross-platform mobile apps: one fixed price, a working demo every week, and the store submission handled for you.
