Flutter vs React Native: Which is Better for your Startup?

​Flutter is an open-source UI software development kit created by Google. It's based on Dart (A programming language influenced by Java, C#, and Swift) and designed natively to compile mobile, web, and desktop apps while doing mobile-first projects.


React and React Native provide a broader ecosystem. JavaScript is ubiquitous in web dev allowing the integration of frontend, backend, and mobile services in a compatible way thanks to easier integration with existing JavaScript libraries. Developers can also use the same code base for web/mobile platforms.

React + React Native
Development Language
Learning Curve
Moderate (widely used JavaScript)
Steeper for those unfamiliar with Dart
Community Support
Vast community
Growing community
Development Speed
Fast due to widespread JS knowledge.
Fast due to hot reload feature.
Bundling JS assets and dependencies for web and native code for mobile
(AOT) Native binary for mobile and compiles to JavaScript for web
High for Web and Native in Mobile due to direct access to device features.
Can vary in Web and Excels in Mobile (ARM code: fast rendering).
Support iOS, Android, and all web browsers.
Also supports all platforms along with desktop & embedded devices.
Excellent for web, good for mobile with React Native
Excellent for mobile, improving for web.
Tooling and Libraries
Extensive and Mature ecosystem with numerous libraries, pre-built & plugins.
Extensive, but less mature than JS + active contributors to update libs & plugins.

Choose Flutter as part of your Tech Stack if:

  • You want to build native-looking apps for multiple platforms with a single codebase.

  • You prioritize rapid prototyping and iterative development.

  • You value smooth performance and visually stunning UIs.

On the other hand, choose JS if you need a large talent pool and a flexible ecosystem, or if your focus is primarily on web applications and if you have expertise and the rest of your development is based on JavaScript libs or frameworks.

Flutter or React Native for Tech Stack? CTO's Insights

This year, CTOs carefully consider Flutter's mobile-first approach rather than JavaScript's extensive ecosystem, due to the importance of high user experience and the migration of users into mobile apps. And while Flutter is a robust framework ideal for complex animations and UI displacement in mobile development plus its single codebase approach, it is not advisable to sacrifice the cross-platform flexibility of a tech stack with Node.js for the backend, React for the frontend and React Native for mobile that offers create a complete software solution without sacrificing web, SEO, and maintainability.
