What Makes a Great Cross-Platform Development Framework in 2025?

To define the best framework for cross-platform mobile development, we want to pay attention to the following criteria:

• Performance & User Experience. A top-tier framework should deliver seamless, native-level performance. This ensures smooth user interactions, quick load times, and a delightful user experience. Also, a consistent UI/UX design across all platforms is important for business. If you are looking for a great framework, pay attention to what tools and libraries it provides. It helps maintain a consistent look and feel, regardless of the device.
• Development Speed & Cost. Using the right tools for cross-platform application development can help you launch your product faster. This allows you to release your minimum viable product (MVP) sooner. When choosing the framework, opt for the one that will reduce the time and cost required to launch the app and start making a profit more quickly.
• Scalability & Maintenance. It is wise to consider future perspectives from the very start. Look for systems that support more users and adapt to changing business needs without losing performance. Another crucial aspect is future maintenance. A well-structured codebase simplifies updates, bug fixes, and future enhancements.
• Developer Ecosystem & Community. Some cross-platform mobile app development frameworks and technologies are more popular among developers or have a more accessible learning curve. Therefore, companies have access to a broader talent pool. Also, a strong developer community is a big advantage for a framework. It provides helpful resources, tutorials, and support forums.
• Platform Coverage. A good framework works flawlessly on many platforms, including mobile (iOS, Android), web, and desktop. Still, most solutions show better performance on some of them. Keep your objectives in mind and choose a framework that performs best on the platforms of your choice.

By looking closely at these factors, businesses can choose a cross-platform framework that meets their goals and provides great user experiences.

• Native Script for apps with custom native integrations, applications requiring full hardware functionality, cross-platform apps where performance is critical
• PhoneGap for simple apps like calculators, forms, or content-based apps, early-stage MVPs, apps with limited performance and native feature needs.

Flutter

Flutter is one of the most popular mobile app development frameworks in 2025, gaining even more popularity over time. Google created this platform to help developers quickly build attractive and fast apps for iOS and Android. There’s also a wide range of widgets and tools that come in handy when developing beautiful and responsive applications.

Apps built with Flutter show fast performance and are highly customizable. This framework is popular among developers because of its flexibility and simplicity. It helps shorten the development cycle while maintaining quality and functionality.

Stfalcon's developers prefer Flutter over other frameworks, and here's why:

• Ability to create apps with a single codebase. It saves specialists a significant amount of time and effort.
• Dart programming language. Dart is widely acclaimed for being fast, reliable, and easy to use.
• Hot reload feature. The ability to see changes in real time makes the development process much faster and more efficient. You also don’t need to restart the app every time there's a change in the code.
• Flutter's widget library. It provides pre-made functionality, which reduces overall coding time. The widgets are easily customizable, allowing developers to create unique UIs that match the app's look and feel. You can use widgets as building blocks to create complex and interactive user interfaces.

Flutter's best use cases: eBay, Google Pay, BMV.

One of Stfalcons most successful cases with Flutter is BingeBooks app. Our developers created a mobile application for iOS and Android that lets book lovers discover new works and exchange recommendations. Its main functions are content search, book browsing, and user list management.

Best use cases: Facebook, Skype, Shopify.

Kotlin Multiplatform

Kotlin Multiplatform is gaining recognition as a robust solution for cross-platform app development. JetBrains, the company behind Kotlin, developed this technology. It lets you write most of your app's code once and then use it on different platforms.

Kotlin Multiplatform has a major benefit: it works well with the Kotlin programming language. Its advantages include Kotlin's concise syntax, strong type system, and a rich standard library. Devepolers appreciate Kotlin for being simple and safe. It works well with existing Java code, making it a good choice for developers who are used to working in the Android environment.

The framework is flexible and has a modular design. This helps developers build customized and efficient applications. Kotlin Multiplatform is an excellent option for teams that want a consistent development approach. It helps create high-quality performance and user experience on various platforms.

Ionic

Ionic is a popular, open-source, free mobile cross-platform framework based on Angular. Developers use JavaScript, HTML, and CSS to create applications with effective performance and appealing interfaces.

One of the reasons Ionic is so convenient is that it accesses native features like the Audio Recorder, GPS, and Camera via Cordova plugins. Due to this, developers can create hybrid apps with a native-like look and feel.

Ionic offers a great choice of UI components and tools that can be used to create native-like apps.

Still, the framework has its drawbacks, and the most significant one is security risks. Applications built on Ionic rely on web technologies and are packaged as hybrid apps. It presents such risks as data leakage and unauthorized access. To prevent that, developers need to implement robust security measures.
