React Native vs Flutter: which should you build your app with?
Both build iOS and Android apps from one codebase, and both are mature. The real differences are language, rendering, ecosystem and your team. A plain comparison and a recommendation.

Short answer: choose React Native if your team already works in JavaScript or React, or you want to share code and people with a web product. Choose Flutter if the interface itself is the product — heavy custom design, rich animation, and pixel-identical screens on every device. Both are mature, both are used in large production apps, and either is a sound choice for most business apps. The deciding factor is usually your team, not a benchmark.
The comparison at a glance
| React Native | Flutter | |
|---|---|---|
| Backed by | Meta | |
| Language | JavaScript / TypeScript | Dart |
| How it draws the UI | Uses the platform's native components | Draws every pixel with its own rendering engine |
| Look across devices | Feels native to each platform | Identical on every platform |
| Ecosystem | Very large, shares npm with the web | Smaller but well curated (pub.dev) |
| Code sharing with web | Strong, especially with React and Next.js | Possible, less common for content sites |
| Hiring | Large pool of JavaScript developers | Smaller pool, often very focused |
| Best for | Business apps, teams with web skills | Design-led apps, custom UI, animation |
Performance: closer than the arguments suggest
For forms, lists, feeds, bookings and checkouts — most business apps — users cannot tell the difference. Flutter's own rendering engine gives it an edge in complex animation and graphics-heavy screens. React Native's newer architecture has narrowed the gap considerably for everyday interfaces. If your app is a game or a video editor, neither may be right; go native.
User interface: native feel vs total control
React Native renders real platform components, so an iOS user gets iOS behaviour and an Android user gets Android behaviour with little effort. Flutter draws everything itself, which means your design looks exactly as designed everywhere — ideal for a strong brand, but you must deliberately recreate platform conventions where users expect them.
Ecosystem and integrations
React Native benefits from the whole JavaScript world: analytics, payments, maps and most SaaS vendors ship a React Native library. Flutter's package ecosystem is younger but solid for mainstream needs. For an unusual integration — a specific payment gateway or hardware device — check that a maintained package exists for your choice before committing.
Team and hiring
This is where most decisions should be made. If your web product is built in React or Next.js, React Native lets the same people and much of the same logic serve both. If you are building a mobile-first product with a dedicated team, Flutter's single language and tooling are a pleasure to work in. Changing later is a rewrite, so pick the one you can staff for years.
Cost
Both save a similar amount over building iOS and Android separately. Cost differences come from the team's familiarity, not the framework. Our guide to mobile app development cost covers what really moves the number.
Our recommendation
- A business app with a web counterpart — booking, ordering, account management: React Native.
- A design-led consumer app where the interface is the selling point: Flutter.
- An MVP to test an idea quickly: whichever your team knows best. Speed of learning beats framework choice (see how to scope an MVP).
- Heavy native features — advanced camera, AR, background processing: consider native, or a cross-platform app with native modules.
We build on standard, well-supported technology on purpose — React, Next.js and Flutter — so what we hand over stays maintainable whether we keep working on it or you take it in-house. The same thinking applies to websites; see WordPress vs a custom website.
Still undecided? That is the first conversation in our software engineering work. Tell us what the app needs to do.
