Choosing The Best Mobile App Framework
Progressive Web App (PWA)
A Progressive Web App (PWA) differs significantly from a traditional web app. In a typical web app, when a request is made to a server, the server generates all the code and sends it back to the browser, which then displays what the server renders. In contrast, with a PWA, when the browser makes a request, all the data is downloaded to the user’s mobile device, and the browser handles all the rendering. This approach allows users to interact with a website as if it were a native mobile app.
The most significant advantage of PWAs is that they do not need to be packaged separately or distributed through app stores. Instead, they can be published online and accessed through a web browser on a computer, smartphone, or tablet. When a user visits the link, the PWA is downloaded and installed locally on the mobile device. This enables developers to push out new versions of the app directly to users, who can receive updates simply by restarting the app.
While native apps built with other frameworks require distribution through app stores and must be reviewed by Google and Apple before being published on Google Play and the App Store, PWAs bypass this process. The review process can take several days and might result in the app being rejected. However, this review process has its benefits, as it involves a thorough examination of the code by Apple and Google, which can identify security risks and other vulnerabilities.
Overall, PWAs offer a flexible and efficient way to distribute and update apps without the need for app store approval, making them a compelling option for many developers. However, the security and quality assurance provided by the app store review process remain valuable for ensuring the safety and reliability of native apps.

Owner
Most web frameworks can be adapted to run as Progressive Web Apps (PWAs) by incorporating the necessary PWA principles and features. However, the ease of implementation and the level of built-in support for PWA functionalities vary between different frameworks.
Some examples of web frameworks that have strong support for creating PWAs include React.js, Vue.js, Ionic, Angular, and Blazor WebAssembly.
Tailored
UI / UX
In Progressive Web Apps (PWAs), each framework is responsible for rendering the entire user interface (UI) and user experience (UX) using the technologies specific to that framework. For example, Blazor uses C#.NET, while React relies on JavaScript. If you want to add a button or any other component, the chosen framework must render it. Similarly, for navigation, you need to create the navigation stack yourself, and if you want animations, you have to implement them manually.
In contrast, native frameworks provide most of these features out of the box through their native APIs. This means that developers get pre-built components, navigation systems, and animation tools directly from the platform, making the development process smoother and more integrated.
The performance of a PWA’s UI is constrained by the capabilities of the web browser being used. While this is not an issue for most applications, it can become a potential problem for apps with highly complex UIs that require high performance. PWAs are essentially websites running on mobile devices, and while they offer flexibility and cross-platform compatibility, they may struggle to deliver the same level of performance as native apps in demanding scenarios.
Native frameworks benefit from deep integration with the operating system, allowing them to deliver a more consistent and high-performance user experience.
Fast
Development Speed
The development speed for Progressive Web Apps (PWAs) is significantly faster than using first-party native tools for iOS and Android. With native development, you need to develop the same app twice—once for iOS and once for Android. In contrast, with a PWA, you develop the app once, and it runs on both platforms, enabling a much quicker time to market.
This advantage extends to maintenance as well. Since PWAs do not need to be published through app stores, updates with new features and bug fixes can be pushed out much faster compared to native apps. This streamlined process allows for more agile development cycles and quicker response times to user feedback.
Additionally, the ability to update the app directly without going through the app store review process means that developers can ensure that all users have access to the latest version of the app as soon as it is available. This can be particularly beneficial for fixing critical bugs or rapidly iterating on new features.
Overall, the faster development and deployment process of PWAs make them an attractive option for many projects, particularly those that benefit from quick iterations and the need to support multiple platforms with a single codebase.
Medium
Maintenance costs
Maintenance costs for Progressive Web Apps (PWAs) are generally lower than using first-party native tools for iOS and Android. Since a PWA is developed once and runs on both platforms, the costs associated with maintaining separate codebases for each platform are eliminated. However, there are still potential risks that could make maintaining PWAs more expensive compared to some native frameworks, which will be discussed later in this article.
It’s important to note that maintenance costs typically represent the largest portion of the total cost of an app, often accounting for around 80% of the total expenses over the app’s lifetime. When Apple or Google introduce new guidelines for how apps should look and behave with specific UI elements for their platforms, PWAs require manual updates to comply with these guidelines. Developers must rewrite and adjust the code to align with the new standards. In contrast, native frameworks that utilize platform-specific APIs for UI elements automatically incorporate these changes, reducing the effort required to update the app.
Additionally, while native frameworks benefit from deep integration with the operating system, allowing for seamless updates and feature additions, PWAs might need more manual intervention to achieve the same level of conformity and performance. This can sometimes offset the initial cost savings from using a single codebase for multiple platforms.
Despite these challenges, PWAs offer significant advantages in terms of reduced maintenance costs and quicker updates. The ability to deploy updates directly without going through app store review processes ensures that users always have access to the latest version of the app. This can be particularly beneficial for rapidly fixing bugs or rolling out new features.
In conclusion, while PWAs present a cost-effective solution for many applications, it is essential to consider the potential complexities and manual efforts required to maintain compliance with evolving platform guidelines. Balancing these factors is crucial, as maintenance costs typically constitute the majority of an app’s total cost over its lifetime.
Medium
Performance
The performance of Progressive Web Apps (PWAs) is generally good, and for most users, there won’t be any noticeable difference between simple actions, such as button clicks, when compared to frameworks that use native APIs. Although there is a measurable difference—where a button click in a PWA might take around 100ms compared to around 10ms with a native framework—this difference is not perceptible to users in the vast majority of applications.
However, these milliseconds can be crucial in specific scenarios, such as game development, where every millisecond can impact the user experience. In such cases, performance is critical, and the slight lag in PWAs can be a disadvantage. Therefore, for applications where performance is paramount, native apps have a clear edge over PWAs.
PWAs cannot offer the same level of performance and quality as native apps because they rely on the browser’s capabilities and limitations. This dependency means that, while PWAs are highly functional and versatile, they might not be suitable for performance-intensive applications that require the highest responsiveness and efficiency, such as in gaming or real-time data processing, native apps continue to be the better choice.

Relatively Mature
Maturity
Progressive Web App (PWA) frameworks have been around for a while now and are continually maturing. Although they are not as mature as some other frameworks, they have made significant strides in recent years that makes them a strong contender in the mobile app development landscape.
Despite not being as mature as native frameworks, PWA frameworks offer a robust set of features that cater to a wide range of application needs. This ongoing development means that developers can expect continuous improvements and updates, enhancing the capabilities and performance of PWAs over time.
The maturity of PWA frameworks can be seen in the comprehensive support for modern web technologies, including service workers, web app manifests, and push notifications. These features enable PWAs to offer a user experience that rivals native apps in many aspects.
Furthermore, the growing community and increasing adoption of PWA frameworks contribute to their maturity. As more developers use and contribute to these frameworks, the ecosystem becomes richer with libraries, tools, and best practices. This collaborative environment accelerates the evolution of PWA frameworks, making them a more viable option for mobile app development.
Limited
Feature Access
The specification for Progressive Web Apps (PWAs) was initially designed for browsers running on laptop computers, not mobile devices. As a result, PWAs do not have access to the full range of functionalities available on mobile devices.
However, PWAs can still leverage certain device-specific features, such as the camera, push notifications, and offline capabilities, by using web APIs. These features enhance the user experience and allow PWAs to function similarly to native apps in many respects.
It’s important to understand that PWAs cannot utilize all the device-specific functionalities that native apps can. This limitation is particularly relevant when it comes to meeting specific user requirements and expectations. For example, advanced features like precise sensor access, background processing, and deep integration with the operating system are areas where PWAs fall short compared to native apps.
When considering the development of a PWA, it’s critical to have a clear understanding of both the current and potential future technical requirements of the app. This foresight will help determine whether a PWA can meet the desired functionality and performance standards or if a framework with native capabilities is a better choice.
Yes & No
Open Source
When developing mobile applications with Progressive Web Apps (PWAs), it’s important to note that some PWA frameworks are open source, while others are not. If open source is a significant factor for your project, it’s advisable to research this aspect thoroughly before making a final decision on which PWA framework to use.
Open source frameworks offer several advantages, including transparency, community support, and the ability to customize the code to fit specific needs.
