March 13th, 2024

Businesses especially start-ups are going gaga over opting for cross-platform app development. Reasons are many including better reach to prospects, cost and time effectiveness, faster time to market, high performance across all platforms and devices, easy amenities and the list continues.

This leads us to find the best cross-platform app development framework or programming language that developers can leverage to develop the desired mobile or web application. As per Statista, the most used cross-platform development framework is Flutter.

Flutter’s rising popularity is quite known among developers. Let us find out more about flutter (meaning, features, companies using flutter, etc.).

What is Flutter?

Flutter is called many things by the developers whether it be:

  • Google’s UI toolkit
  • Open-source mobile app SDK (software development kit)
  • Open-source mobile app development platform
  • Open-source UI software development kit
  • Cross-platform software development kit (SDK)

And more but one thing that you will find all over on the official site of Flutter is the words “single code base” which makes high-quality native Flutter app development (mobile, web, desktop, and embedded apps) that work across various platforms.

Flutter’s built-in programming language is Dart(a reactive programming language with a syntax like JavaScript). The former comprises a software development kit (SDK) and a widget-based UI library. The widgets enable developers to build both visual and functional components of the app.

Flutter Features

  • Platform-agnostic
  • Library of pre-made widgets
  • Layered architecture
  • Hot-reload function
  • Fast Prototyping
  • Extensible and open model
  • Expressive and Flexible UI
  • Supports stock platform app development
  • powered by language optimized for fast apps
  • Suitable for MVP (Minimum Viable Product) apps
  • Native performance
  • Ease of debugging
  • Features automated testing
  • Available on different IDEs

The companies using Flutter or having a flutter in their tech stack for building apps are Alibaba Group, Google Pay, Dream11, Kotak, CrowdSource, Bytedance, Baidu, BMW, eBay, Geeky Ants, Tencent, SpaceX Go, and more.

Having said everything good about Flutter, it is wise to have one thing clear not every project requirement may find Flutter as a framework that fulfills it. This is where you need to find the Flutter competitors or alternative to Flutter which may not be the most used framework but works best for your project requirements.


12 Best Flutter Alternatives For Cross-Platform Apps

Let us explore these flutter competitors in detail.

  1. React Native

    This ideology is the reason this open-source JavaScript framework (released by Meta Platforms, Inc. previously Facebook on March 26, 2015) is known as one of the most developer-friendly frameworks.

    Flutter was able to beat React Native by 4% as per the statistics making Flutter the most used cross-platform by 42% of developers and React Native stands at 38% making it the best Flutter alternative.

    Developers use React Native (also known as RN) mobile-first platform to natively render mobile applications for iOS and Android. It is a cross-platform mobile application written entirely in JavaScript using React and offers an extensive collection of external UI kits to use during React Native development to get true native capabilities.

    React Native Features

A lot goes into the decision-making of choosing the right framework for your development project. The business owner’s or developer’s mind is surrounded by a lot of questions that they seek an answer to when considering alternatives to Flutter or any other framework.

  • Is good documentation available?
  • Does the framework have an active user base?
  • Would the framework make your development teams more productive?
  • Can your developers easily reuse code?
  • How active is the framework community?
  • Does it offer in-built unit testing?
  • What are the “bonus” features of the framework?
  • Does the framework have any specific Hosting Prerequisites?
  • Does the framework have any licensing costs?
  • Is the framework suitable for businesses with limited resources?

And the list continues.

Developers who have worked with Flutter often struggle to find an alternative to this most chosen cross-platform. All these frameworks have some things in common with Flutter making them appropriate alternatives to Flutter for most projects.

However, the final decision is still affected by the answers that you are seeking corresponding to specific requirements of the overall development process and business goals. This way you would have a platform that works best for your project’s requirements and is cost as well as time effective.

Flutter is indeed one of the best choices for teams seeking cross-platform development, but this does not necessarily mean it is the best and developers are only compromising on the quality of the framework when choosing other frameworks or programming languages for mobile app development.

So, weigh each framework or programming language on your requirement criteria and choose the one that gets the best answers to all such requirements questions as above.
