What are Progressive Web Applications?

Progressive Web Applications are web applications that give a native app-like experience. 

Simply put, a Progressive Web App (PWA) is a website that has all of the features of an app. PWAs allow you to create a version of your website or eCommerce store that is quicker, more dependable, and more engaging.

PWAs can do almost everything that native applications do, including work offline, access your camera and microphone if needed, and use GPS.

Difference between native, hybrid, and Progressive apps

Native application

Native applications are built to operate on a certain platform. They require separate codebases and associated complexity of the application can make the most of a device’s inherent capabilities and hardware.

Hybrid application

Hybrid applications rely on framework instead of using programming languages. However, in case of hybrid applications, one codebase can be shared in most scenarios. 

Progressive Web Application 

Progressive Web Applications are a hybrid between website and applications  that runs on one codebase across all platforms (web, mobile, desktop). In such applications, access to a device’s native capabilities is restricted, but sufficient for most use cases.

Key features of Progressive Web Applications 

PWAs (Progressive Web Apps) are designed and developed to proceed smoothly and provide a great user experience. A faster-loading app promotes improved client retention and a higher conversion rate. Because of its high-performance characteristics, PWA is being adopted by businesses across the board. 

The following are some of PWA’s must-have features:

Easy to maintain

A PWA is easy to maintain because it updates automatically. Simply visit the page again, and they will have the most recent version. Post-launch maintenance is as simple as opening a browser with a PWA.

Secure and faster

These apps operate over HTTPS, ensuring optimum privacy and security for both users and website data. Secure connection safeguards sensitive data against unwanted access and other threats.


PWAs are SEO-friendly and easily indexed by search engines. It has a lot of advantages when it comes to consumer acquisition and visibility. It’s not easy, but it’s a lot easier to optimise progressive web apps using customised SEO techniques.

Progressive web apps are reliable as they run on the user’s device independent of network access. This implies that users may use these apps to see saved data in offline mode, i.e. when there is no or limited internet access.


Progressive Web Applications deliver high performance applications. Users that utilise PWA get a quick response to whatever action they take. With PWA, the user can expect the website to load quickly and be error-free, with no slow-responding interfaces, erratic navigation, or unnecessary scrolling.

Responsive design

Progressive Web Apps (PWAs) are responsive, meaning they adapt to different screen sizes. These applications work with a variety of operating systems and are easily available on a variety of devices, including smartphones, tablets, desktops, and laptops.

Offline availability 

Unreliable connectivity difficulties frequently impact and degrade the user experience. Even if your internet connection is lost, PWA is still available. It implies that if you go to the site offline, you’ll be able to see the data that has been saved.

Push notifications 

Progressive Web Apps are installed on the user’s home screen and do not require the user to visit the app store. These applications employ push notifications to re-engage users and provide an exceptional user experience.

Low development cost

PWAs are less expensive than native mobile apps since they are developed with modern development tools and methods. Furthermore, you receive data protection, security, minimal app complexity, and cross-platform software at a far lower cost.

Technical Requirements of a PWA 

Only a few technological requirements are required to assure the effective creation of Progressive Web Apps. A website must-have a web manifest file, use HTTPs, and register a service worker. Let’s take a deeper look at all three technical prerequisites for creating a PWA. 

HTTPS: To provide comprehensive platform security, Progressive Web Apps must be launched over a public web server, which may be accomplished via the HTTPS protocol.

Service Workers: PWA offers offline access via service workers, which are JavaScript files that act as a bridge between the app and the network.

App Manifest: One of the most important technical prerequisites for creating a PWA. The app manifest is a JSON file that contains information about the PWA’s interaction with the browser.

Why should you use Progressive Web Applications? 

Progressive Web Applications are more in use because they provide better experiences than web applications. However, building and maintaining native apps requires a significant amount of time and effort, not to mention the associated costs.

If you are looking to develop an application for Android or iOS, you must code your app for each one. PWAs, on the other hand, do not necessitate coding for each platform. They were created with the “code once, use everywhere” concept in mind. Once your PWA has been coded, it may be utilised in-browser (as a website or web app), on desktops, and on mobile devices.

This frequently results in increased performance, and, ultimately, a more inexpensive application that provides your customers with a good user experience (UX). 

When should you consider Progressive Web Application?

Situations in which you should consider deploying a progressive web app include:

  • You don’t have the funds to create a full-fledged app.
  • You must reach a larger audience.
  • You must go to market quickly.
  • Proper search engine indexing is critical.
  • Cross-platform compatibility is critical to your company’s success.

If you satisfy any of the aforementioned requirements, you most likely require a progressive app.
