Progressive Web Apps: Why Businesses Are Opting for Them?

Progressive Web Apps (PWAs) have emerged as a popular choice. PWAs are web applications that offer the user experience of a native app, with the accessibility and convenience of a website. With their ability to improve user experience, reduce development costs, and increase engagement, PWAs have become an attractive option for businesses.

In today's mobile-first world, PWAs have emerged as a game-changer for web development, offering businesses the opportunity to create fast, reliable, and engaging web experiences. PWAs were first introduced by Google in 2015, as a response to the growing use of mobile devices and the limitations of native mobile apps. They aimed to bridge the gap between websites and native apps, offering users a seamless experience. Since then, PWAs have gained popularity due to their benefits in terms of accessibility, speed, and user engagement. PWAs are gaining popularity because they offer several advantages over traditional mobile apps and websites. They load quickly, even on slow or unreliable networks, and can be used offline. They can also be installed on a user's device like a native app, but without the need for downloading from an app store. Additionally, PWAs are cost-effective to develop and maintain, making them an attractive option for businesses looking to improve user experience and increase engagement.

Advantages of PWAs for Businesses

Improved User Experience (UX)

Improved user experience is one of the primary advantages of PWA for businesses. Here are some of the key reasons why:

Faster load times: PWAs have been shown to load faster than traditional mobile apps, even on slow or unreliable networks. This can significantly improve the user experience and reduce bounce rates.

Offline functionality: PWAs can work offline or with limited connectivity, providing a seamless experience for users. This is especially important for businesses that have customers in areas with poor network coverage.

Push notifications: PWAs can send push notifications to users, even when the app is not open. This can be an effective way to engage customers and keep them coming back to the app.

Greater accessibility: PWAs can be accessed from any device with a web browser, making them highly accessible. This can be especially important for businesses that have customers in areas with limited access to smartphones or high-speed internet.

Better conversion rates: Improved user experience can lead to better conversion rates, as users are more likely to make a purchase or take another desired action. For example, the PWA developed by Lancôme resulted in a 17% increase in conversions.


One codebase: PWAs can be developed using a single codebase, which means they can be deployed across different platforms and devices, reducing development costs.

No need for app stores: PWAs can be installed directly from a website, without the need for app stores, reducing distribution costs.

Less maintenance required: PWAs require less maintenance than traditional mobile apps, as updates can be pushed directly to users' devices, without the need for app store approval.

Lower development costs: PWAs can be developed at a lower cost than traditional mobile apps, as they require less development time and resources.

The cost-effectiveness of PWAs makes them an attractive option for businesses looking to improve user experience and engagement, without breaking the bank. Forbes reported that Twitter Lite, a PWA developed by Twitter, resulted in a 70% decrease in data usage and a 20% increase in pages per session, while also being 30 times smaller than the native app.

Technical Aspects of PWAs

Comparison of PWAs and native mobile apps

There are several technologies and tools available that make it easier to create high-quality applications. Here are some of the most commonly used technologies and tools for PWA development:

Service Workers: Service Workers are a key technology used in PWAs that enable offline functionality and push notifications.

Web App Manifest: The Web App Manifest is a JSON file that provides information about the PWA to the browser, such as the app's name, icon, and theme color.

HTTPS: PWAs require a secure HTTPS connection to ensure that user data is protected.

Responsive Design: PWAs should be designed to work on any device or screen size, using responsive design principles.

When it comes to comparing PWAs and native mobile apps, there are several key differences to consider. PWAs are essentially websites that can be installed on a user's device like a native app, without the need for an app store. Here are some of the main differences between PWAs and native mobile apps:

Development costs: PWAs are generally cheaper to develop than native mobile apps, as they can be developed using web technologies and deployed across multiple platforms.

User experience: Native mobile apps can offer a more seamless user experience, as they are designed specifically for the device they are running on. However, PWAs are catching up and can offer a similar experience.

Distribution: Native mobile apps are distributed through app stores, while PWAs can be installed directly from a website.

Challenges in developing PWAs

While PWAs offer several advantages over traditional mobile apps, there are also some challenges that businesses need to be aware of when developing PWAs. Here are two of the biggest challenges in developing PWAs:

Browser compatibility: One of the biggest challenges in developing PWAs is ensuring that they work consistently across different browsers and devices. Since PWAs use new web technologies like Service Workers and Web App Manifest, browser compatibility can be a challenge. However, there are tools available to help with browser compatibility testing, such as BrowserStack and Sauce Labs.

App discoverability: Unlike native mobile apps, which are typically distributed through app stores, PWAs are installed directly from a website. This can make it more challenging for businesses to promote and market their PWAs. However, there are several strategies that businesses can use to improve app discoverability, such as optimizing their website for search engines, using social media and email marketing to promote the PWA, and leveraging app directories like the Microsoft Store or Google's Chrome Web Store.

Despite these challenges, PWAs offer many benefits to businesses, including improved user experience, cost-effectiveness, and the ability to work offline and send push notifications to users. By understanding the technical aspects of PWAs and the challenges involved in developing them, businesses can make informed decisions about whether PWAs are the right choice for their needs.

Best Practices for Developing PWAs

Design and User Experience (UX)

Developing a successful PWA requires attention to design and user experience (UX). Here are some best practices for designing PWAs:

Responsive design: PWAs should be designed to work across a variety of devices and screen sizes. Using responsive design techniques can help ensure that the PWA looks and functions well on different devices.

Navigation and UI elements: PWAs should have intuitive navigation and UI elements that are easy for users to understand and interact with. This can include using familiar UI patterns like tabs, menus, and buttons.

Offline capabilities: One of the key benefits of PWAs is the ability to work offline. Designers should consider how the PWA will function when offline, and provide clear messaging to users about what features will work and what features require an internet connection.


Performance is a critical aspect of PWAs. Here are some best practices to ensure that your PWA is fast and responsive:

Loading speed optimization: PWAs should load quickly, even on slow or unreliable networks. To optimize loading speed, developers should consider techniques like lazy loading, preloading, and minification of code.

Resource optimization: PWAs should use resources efficiently, particularly when it comes to data usage. This can include techniques like compressing images and reducing the number of network requests.

Caching strategies: PWAs can use caching strategies to store frequently used resources locally on the user's device, reducing the need for network requests. Developers should consider using techniques like Service Workers and the Cache API to implement effective caching strategies.

Security and Privacy

Security and privacy are critical considerations when developing PWAs. Here are some best practices to ensure that your PWA is secure and respects user privacy:

HTTPS implementation: PWAs should use HTTPS to encrypt all data transmitted between the user's device and the server. This helps to prevent eavesdropping and tampering with the data.

Data storage and transmission security: Developers should ensure that all data stored on the server and transmitted to the user's device is secure. This can include measures like encryption and access controls.

User data privacy: PWAs should respect user privacy by not collecting more data than necessary, and by providing clear information about data collection and usage. Developers should also ensure that user data is securely stored and protected.

Use Cases of PWAs

PWAs are gaining popularity across a range of industries due to their ability to provide an app-like experience without requiring users to download an app from the app store. Here are some of the use cases of PWAs:
