モバイル・アプリの構築に最適なのはReact NativeとFlutterのどちらか

Published: 23 January 2023


React NativeとFlutterは、ネイティブに近いモバイル・アプリ・エクスペリエンスを実現する代表的なフレームワークである。ネイティブ・アプリの構築に向けて、クロスプラットフォーム開発ツールを探しているソフトウェア・エンジニアリングのリーダーは、本リサーチノートに挙げた要素を比較検討し、開発チームのためにReact NativeとFlutterを評価すべきである。

Included in Full Research


  • Androidソフトウェア開発キット (SDK) であるAndroid Studioや、iOS SDKであるXcodeなどのネイティブ・ツールセットを用いれば、開発者は、これらのネイティブ・モバイル・プラットフォームの最新イノベーションを確実に取り入れることができる。しかし、このメリットと引き換えに、アプリとスキル両方のポータビリティが失われることも理解している。

  • React Nativeアプリは、モバイルOS上で直接実行されるネイティブ・コードと、スクリプト言語とのバランスを取る。このフレームワークは高度な柔軟性と生産性をもたらす。

  • 優れたユーザー・エクスペリエンス (UX) を提供するには、アプリのパフォーマンスが極めて重要である。Flutterアプリはマシン・コードに直接組み込まれるため、解釈プロセスのパフォーマンス・リスクがまったく生じない。



  • 開発者がWebアプリにReactや他のJavaScriptフレームワークを使用しており、iOSとAndroid向けにJavaScript言語を用いて単一のコードベースからWebアプリとモバイル・アプリの両方を構築しようと試みている場合、React Nativeを使用する。

  • 開発者がDart言語を使用して、iOS、Android、Windows、macOS、またはLinux向けに、単一のコードベースからネイティブ・コンパイルされるモバイル・アプリ、Webアプリ、デスクトップ・アプリを構築する態勢が整っている場合、Flutterを使用する。
