PWAs are web applications that might be mounted on a user’s device in a similar means as native apps can, but they are made with web technologies like HTML, CSS, and JavaScript.

Some companies that offer mobile app maintenance services also offer backing and maintenance for PWAs to guarantee that they continue to function properly over time.

This post will discourse the development of Progressive Web Apps (PWAs), their benefits, and what developers need to know to build them.

The Emergence of PWAs

PWAs were initially offered by Google in 2015, but they didn’t catch on until 2018.

That year, prominent organizations like Twitter, Alibaba, and Starbucks introduced PWAs to improve their mobile web experiences.

PWAs are being employed by a wide range of organizations, from e-commerce to banking, to give a unified user experience across devices.

Benefits of PWAs

PWAs offer numerous benefits to businesses and users alike, counting:

Fast and reliable performance:

Because PWAs are built with service workers, they can load quickly even on slow networks. They may also function offline, giving consumers a dependable experience.

Cross-platform compatibility:

PWAs are compatible with a variety of platforms and devices, including desktops, laptops, smartphones, and tablets.

Improved engagement:

PWAs may be added to a user’s home screen, giving them rapid access to the app and enhancing engagement. They may also provide push alerts to users, which increases user engagement.


PWAs can be built using web technologies, which are often cheaper than building native apps. They also require less maintenance since updates can be pushed automatically.

Improved discoverability

PWAs are indexed by search engines, making them more discoverable than native apps.

Lower bounce rates:

Users are less likely to exit the app when it loads quickly and provides a flawless experience, resulting in lower bounce rates.

App-like experience

PWAs provide an app-like experience without requiring the download and installation of an app from an app store. This makes them more handy for consumers who don’t want native programs cluttering up their devices.

Easy updates

PWAs may be updated in the background, eliminating the need for users to update the app manually. This guarantees that users are always using the most recent version of the program.

Greater reach

PWAs may reach a larger audience than native apps since they function across several platforms and devices.

Improved SEO

PWAs can improve SEO since they are indexed by search engines and can be discovered through search results.

Better analytics: Because PWAs are built with web technologies, developers can track user behavior and engagement using web analytics tools.

This can provide valuable insights for improving the app and user experience.

Lower development costs

PWAs may be constructed with web technologies, which are frequently less expensive than native app development.

Furthermore, because PWAs work across multiple platforms and devices, developers are not required to create separate versions of the app for each platform.

Creating PWAs

To create a PWA, developers must adhere to specified rules and employ specific tools and technologies. Here are some important things that developers should be aware of:

  • Use HTTPS: To ensure security, PWAs must be delivered over HTTPS.
  • Employ a service worker: Service workers are essential for making PWAs function offline and load rapidly. Developers must create a service worker capable of caching the app’s assets and providing an offline experience.

There are many skilled developers available that can help you construct a quick, dependable, and engaging web app if you are seeking a reputable Flutter app development company to build your PWA.

  • Create a manifest file: A manifest file is used to store app metadata such as the program’s name, icon, and theme color. The browser uses this file to install the app on the user’s device.
  • Optimize for mobile: Because PWAs are frequently visited via mobile devices, developers must ensure that the app is mobile-friendly.

Push notifications may enhance user engagement; thus, developers should consider using them in their PWAs.

Popular Examples of PWAs

There are several well-known instances of PWAs built by corporations from various sectors. Here are a couple of such examples:

One of Twitter Lite’s primary characteristics is its ability to run on slower network connections.

It is designed to load swiftly even on 2G or 3G networks, making it usable in areas where high-speed internet is unavailable.

Twitter Lite also includes features seen in native programs, such as push notifications, an offline mode, and the ability to add the app to the home screen of a mobile device.

It also supports several languages, allowing users to use the app in their preferred language.

Flipkart Lite

Flipkart Lite is a PWA created by the Indian e-commerce business Flipkart. It offers consumers a quick and flawless purchasing experience, even on sluggish networks. It also has push alerts and an offline mode.


Starbucks created a PWA to give its consumers a quick and easy ordering experience. The PWA enables consumers to order and pay for their beverages ahead of time, minimizing in-store wait times.

PWAs are a compelling alternative to native apps, offering consumers quick, dependable, and engaging experiences.

PWAs may be built with the correct tools and technologies to function across multiple platforms and devices, enhancing discoverability and lowering expenses.
