What each one is
React Native is an open-source framework from Meta. Developers write in JavaScript or TypeScript using React, and the framework turns their components into the platform's own buttons, lists and text fields. Most teams build with Expo, a set of tools and services that handles builds, updates and common device features.
Flutter is an open-source framework from Google. Developers write in Dart, and Flutter draws every pixel of the interface itself with its own rendering engine instead of using the platform's controls. The same code can also target the web and desktop.
Both projects release several times a year. Details in this comparison were checked against the React Native and Flutter documentation when it was reviewed, and version-specific points will date.
The two at a glance
| React Native | Flutter | |
|---|---|---|
| Language | JavaScript or TypeScript, with React | Dart |
| How the interface is drawn | With each platform's native controls | By Flutter's own engine, pixel for pixel |
| Look and feel | Follows iPhone and Android conventions by default | Identical on both unless you design the differences |
| Sharing with a web product | Logic, types and people shared with a React site | Its own web target. Little is shared with an existing React site |
| Hiring | Draws on the large pool of JavaScript and React developers | A smaller, growing pool of Dart developers |
| Device features | Through a large library ecosystem, and native modules when needed | Through plugins, and platform channels when needed |
| Updates without store review | Supported for the JavaScript part through update services | Possible through third-party services |
| Backed by | Meta, with Expo and a wide community | Google, with a wide community |
When each one fits
Choose React Native when
- Your website or web app is built with React
- Your developers know JavaScript or TypeScript
- The app should use each platform's familiar controls
- You expect to hire, and want the widest pool
- You want to push small fixes between store releases
Choose Flutter when
- The design is custom and must match exactly on every device
- The team already works in Dart, or starts with no web code to share
- The interface is heavy on animation or drawing
- One codebase should also reach desktop screens
- A partner you trust builds in it and will maintain it
What matters less than it used to
Older comparisons spend most of their length on performance. For business apps, which are mostly lists, forms, maps and media, that argument has largely closed. React Native's current architecture removed the bottleneck its critics pointed to, and Flutter's current renderer removed the stutter its critics pointed to. Both feel smooth when built with care and slow when built without it.
The question of which will be abandoned is also asked less. Both have been in production for years at large companies, both are open source, and both have published roadmaps. The realistic risk is not the framework disappearing. It is your app falling behind on updates because nobody was assigned to keep it current.
What the choice costs over time
The first build costs about the same either way. The difference shows later, in three places.
- People. If your web team can also work on the app, one team covers both. If the app needs specialists your company has nowhere else, every change waits for them.
- Upgrades. Apple and Google release new system versions every year, and both frameworks follow. Budget for an upgrade each year whichever you pick.
- Native work. A feature neither framework covers needs platform code in Swift or Kotlin. It happens in both, so ask any partner whether they can write it.
If an app depends on heavy device work throughout, such as continuous background processing or advanced camera pipelines, weigh fully native development as well. Our comparison of native and cross-platform development covers that choice.
A worked example
A clinic group and a fitness brand
Both companies are invented. Each wants one app for iPhone and Android.
- The clinic groupHas a patient website built with React and three web developers. The app books appointments, shows results and sends reminders.
- Its decisionReact Native. The web team extends into mobile, booking logic is shared with the site, and standard platform controls suit a healthcare audience.
- The fitness brandHas no existing web product. Its designers have drawn a distinctive interface with animated workout screens that must look the same on every phone.
- Its decisionFlutter, built by a partner with a Dart team. Nothing existed to share, and exact visual control was the priority.
The clinic chose for its people. The brand chose for its design. Neither chose on benchmarks.
A checklist to decide
Tick what is true. The first four favor React Native and the last four favor Flutter. If the ticks are even, pick the one your team or your partner knows best.
React Native or Flutter
0 of 8 checkedWhat to do next
Write down who will maintain the app in its third year, and what they know today. That answer settles most cases. We build cross-platform apps with React Native, and we say so plainly when a project would be better served by something else.
If you are still shaping the product, planning a mobile app MVP helps you fix the scope before the framework.
Common questions
Is Flutter faster than React Native?
For ordinary business apps the difference is not something users notice. Both now run on modern engines and architectures that removed their earlier weaknesses. Speed in practice depends far more on how the app is written: how lists are loaded, how images are sized and how much work is done on each screen. Judge a team by apps they have shipped, not by framework benchmarks.
Which is easier to hire for?
React Native, in most markets, because it uses JavaScript and React, which a very large number of web developers already know. Flutter developers are fewer but the pool is growing, and Dart is not hard for an experienced developer to learn. If you plan to build an in-house team later, look at who is available where you hire before you choose.
Can we share code between our website and our app?
With React Native and a React website, yes, in part. Business rules, data fetching, validation and type definitions can be shared, and the same developers can work on both. Screens are still written for each. Flutter can produce a web version of the app, but it does not share code with an existing React site.
Will we be stuck if the framework loses support?
The risk is low for both. Each is open source, backed by a large company and used in production by many others, so neither would vanish overnight. The more common problem is neglect. An app that misses a few yearly upgrades becomes hard to update at all. Whichever you choose, plan for maintenance from the first release.
