8 Best Cross-Platform App Development Frameworks for 2021

The development and eventual availability of frameworks that would support development of apps for multiple platforms has heralded a new chapter in the field of mobile app development.  


Developers now have the luxury of choosing either one of two development strategies – create separate native applications or build a single cross-platform app that works seamlessly across platforms. Businesses that foresee a strong potential in multiple geographies and user bases but are limited by financial and time constraints will find that building a cross-platform app is the ideal solution to build a minimum viable product. 


They may also choose cross-platform development if their needs only dictate a simple mobile app with no complex visuals or features. 


Cross platform development frameworks are a boon for businesses and developers alike as it enables them to create mobile apps with the same code base that can run on multiple platforms with infinitesimal changes. Today, there are several cross-platform frameworks available for mobile application development that help build world class applications.


The worldwide mobile app development market is expected to touch $100 billion by 2022.
