React Native: The other major cross-platform choice, rendering to real native components in JavaScript rather than drawing its own in Dart
Flutter
Google’s open-source framework for building apps from one codebase
As of 29 August 2026, Flutter is free to use. Google’s open-source UI framework. Softwr lists it under Mobile Development. Flutter is made by Google, launched in 2017, available on iOS, Android, Web, Windows.
Overview
What Flutter does
Flutter is an open-source framework from Google for building natively compiled applications for mobile, web, desktop and embedded devices from a single codebase. It is written in Dart, a language Google designed for fast startup and ahead-of-time compilation. Flutter differs from most cross-platform toolkits in how it draws. Rather than mapping to the host platform’s native widgets, it renders its own with its own engine, which is why a Flutter app looks identical across platforms and why it can hit high frame rates consistently. That is also the main trade-off: the interface is Flutter’s, not the platform’s, unless you do the work to match each one. The framework is maintained by Google with a large open-source community. The framework is under a Creative Commons Attribution 4.0 licence with code samples under the 3-Clause BSD licence.
What people use it for
- Shipping one app to iOS and Android with a small team
- Interfaces with heavy custom design that need to look identical on both platforms
- Adding web or desktop builds to an existing mobile codebase
- Prototyping quickly where hot reload shortens the design loop

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Flutter.
- Dart is used almost nowhere else, so the language itself is a hiring and learning cost
- Because Flutter draws its own widgets, apps can feel subtly unlike the platform unless deliberately styled per-platform
- Binary sizes are larger than equivalent native apps because the engine ships with the app
- Access to a brand-new platform API waits on a plugin, or on writing platform channel code yourself

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Flutter free?
Yes. Flutter is open source with no licence fee. The framework is under a Creative Commons Attribution 4.0 licence and its code samples under the 3-Clause BSD licence.
What language does Flutter use?
Dart, a language Google designed for fast startup and ahead-of-time compilation to native code.
Can Flutter build for more than mobile?
Yes. The same codebase targets iOS, Android, web, Windows, macOS, Linux and embedded devices, though mobile remains the most mature target.
How is Flutter different from React Native?
Flutter draws its own widgets with its own engine, so the result is pixel-identical across platforms. React Native renders to the real native components of each platform. Flutter uses Dart; React Native uses JavaScript and React.
