What are the Top 5 Cross Platform Mobile App Development Frameworks

Mobile applications have transformed business. Most companies, including SMEs and startups, are using apps for both internal and external software needs. In such a highly competitive market, developers use new tools and frameworks for cross-platform mobile app development to reduce dev time and costs.

By using cross-platform app development, companies can widen the reach of an app while controlling the budget. As a result, most companies prefer cross-platform mobile app development over native mobile app development. 

Moreover, if you want a simple mobile application without complex functions and animation, cross-platform mobile app development works great.

To select the best cross-platform app framework for your requirement, you should consult an experienced developer. The right technology and framework will fuel the growth of your business.  

Before we talk about the most common cross-platform app development frameworks, let’s learn a little about the basics. 

What is a Cross-Platform Mobile App Development Framework?

A cross-platform mobile app development framework is a set of tools or software to develop native-like apps for multiple platforms such as iOS, Android, Windows, Blackberry, and Web with a single codebase.  Cross-platform app development allows you to reach a larger targeted audience at a lower cost and in less time.

As one of the most popular development methods today, most mobile app development companies use it extensively.

Programming languages used in some open-source, cross-platform app development frameworks include:

What Are the Benefits of Cross-Platform Mobile App Development Frameworks Over Native Development?

The benefits of cross-platform app frameworks include reduced costs and faster timeframes. Let’s discuss these advantages in more detail.

Reduced Cost

Cross-platform app development frameworks reduce your overall costs because this method requires fewer resources. That helps you balance quality, budget, and development time.

Reusability of Codes

Also called “Write Once Run Anywhere” (WORA), the reusability of code is one of the biggest advantages of cross-platform frameworks. Developers write the code once and then reuse it on multiple platforms—saving time, effort, and operational costs.

Ease of Deployment and Maintenance

With a single codebase for multiple platforms, an app is easier and faster to deploy, maintain, and update, which results in savings of both time and effort.

Uniform Design

With cross-platform frameworks, you can easily share a unified UI/UX across different platforms while maintaining platform-specific standards. 

Market Reach Expansion

Because you can deploy your app on multiple platforms, you get wider exposure to the targeted audience.
