Web App vs Progressive Web App: Understanding the Key Differences

In the ever-evolving digital landscape, the terms "Web App" and "Progressive Web App" (PWA) often get tossed around, but what exactly sets them apart? Understanding the key differences between Web App and PWA is crucial for developers, businesses, and users alike. Both Web Apps and Progressive Web Apps are designed to offer a seamless user experience, yet they have distinct characteristics that affect performance, offline capabilities, development processes, and security.

This Web App vs Progressive Web App comparison will dive deep into the Progressive Web App features, Web App advantages, and the unique benefits that PWAs bring to the table. From PWA vs Web App performance to Web App vs PWA user experience, this guide will help you navigate the intricate landscape of modern web development.

At its core, a traditional Web App is essentially a website designed to perform like an app, accessible via web browsers. It offers a range of functionalities but often falls short when it comes to offline capabilities and performance. On the flip side, Progressive Web Apps are the next evolution, combining the best of web and mobile apps to deliver an unparalleled user experience.

PWAs are known for their reliability, speed, and enhanced offline capabilities, setting them apart from standard Web Apps. As we explore the differences between Web App and Progressive Web App, we'll also touch upon key aspects like PWA vs Web App development, Web App vs PWA security, and the overall Progressive Web App vs traditional Web App reliability.

By the end of this comparison, you'll have a comprehensive understanding of whether a Web App or a Progressive Web App is the right choice for your next project.

Web App vs Progressive Web App: Understanding the Key Differences

In the digital age, the number of mobile users has skyrocketed, increasing the demand for a better web experience on mobile devices. Whether it's booking a cab, shopping, or finding the nearest restaurant, users expect a seamless experience. Traditional websites often fall short due to slow loading speeds and subpar UIs (User Interfaces). This is where web apps and their more advanced counterpart, Progressive Web Apps (PWAs), come into play.

What is a Regular Web App?

A web app is essentially a website designed to fit any screen, regardless of the device. They are built using front-end technologies like HTML, CSS, and JavaScript, along with back-end technologies such as Ruby, PHP, and Python. Web apps operate through web browsers and can use device features to some extent, but their functionality can vary between different browsers.

Types of Web Apps

  • Static Web Apps
  • Dynamic Web Apps
  • Single-page Apps (SPAs)
  • Multi-page Apps (MPAs)
  • Ecommerce Web Apps
  • Portal Web Apps

Some popular examples of web apps include Google Sheets, Quora, Codepen.io, and Evernote.

What is a Progressive Web App?

A Progressive Web App (PWA) is a more advanced version of a regular web app. The term was coined by Google Chrome engineer Alex Russell. PWAs combine the best of web and app experiences, providing a high-end, seamless experience across both desktop and mobile platforms. PWAs are built using similar front-end and back-end technologies as regular web apps but can also take advantage of frameworks like AngularJS, Vue.js, and ReactJS.

Some popular examples of PWAs include MakeMyTrip, Pinterest, Trivago, Twitter Lite, and Forbes.

Web Apps vs Progressive Web Apps: Key Differences


One of the most significant differences between a PWA and a web app is the ability to install the app. PWAs can be installed on devices (both desktop and mobile), while web apps run within a web browser and cannot be installed. This makes PWAs more accessible and user-friendly.

App-like Experience

Although PWAs use similar technologies as web apps, they offer a user experience that is very close to that of a native app. PWAs can utilize most device features, such as push notifications, regardless of the web browser used. This makes differentiating between a PWA and a native app quite challenging.

Ease of Access

PWAs are lightweight and take up very little space, usually just a few KBs. Unlike web apps, which can only be accessed through a web browser, PWAs can be accessed directly from the home screen or app drawer once installed. They can also be shared via a link, making installation straightforward.

Faster User Experience

PWAs can cache data, allowing them to serve users with images, texts, and other content almost instantly. This reduces waiting times, thereby improving retention rates and user engagement. In contrast, web apps often take longer to load, affecting user experience negatively.

More User Engagement

One of the key benefits of PWAs is their ability to use push notifications and other device features to increase user engagement. Web apps, on the other hand, struggle to achieve the same level of engagement.

Real-Time Data Access

PWAs are always up-to-date as they auto-update when changes occur. While web apps also update automatically, PWAs, being an advanced version, have an edge in this department.

Benefits of Developing a Progressive Web App

Choosing progressive web app development over web app development offers numerous benefits:

Low Development Cost

Developing a PWA is more cost-effective than developing a native app or even a regular web app. You don't need to spend money on app store submissions, and a single PWA can function across multiple devices and platforms. Various PWA frameworks make development easier and more efficient.


PWAs can be indexed by search engines, allowing businesses to leverage SEO to improve their PWA's ranking, thereby attracting more users and boosting sales.

Cross-platform Functionality

PWAs are both cross-platform and cross-browser compatible, meaning a single PWA can function on any device and web browser. This reduces costs and increases potential reach.

Offline Usage

Due to caching, PWAs can store data on the device, enabling users to access content even without an internet connection. This offline capability adds immense value, especially in areas with poor or no internet connectivity.


PWAs are served through HTTPS, making them more secure compared to regular web apps. This ensures data integrity and security, providing a safer user experience.

How PWAs Enhance the Ecommerce Experience

Login via Social Accounts

Social integration allows users to sign up through social accounts like Facebook or Google, reducing sign-up friction and increasing customer acquisition and engagement.

Push Notification Alerts

Push notifications can be sent anytime, even if the web browser isn't open, improving user engagement and retention.

Simplified Payment Processing

Unlike native apps that have limitations on payment providers, PWAs allow you to use APIs under the Web Payments standard, simplifying payment processing.

Shopping with No Internet

PWAs enable users to browse products and even use basic shopping cart functionalities offline, thanks to cached data.

Tracking Unique Analytics

Integrating PWAs with Google Analytics allows businesses to track offline browsing behavior and gain insights into user interactions, helping improve the app's performance.

Case Studies: Success Stories of PWAs


AliExpress, a Chinese eCommerce marketplace, saw an 84% surge in sales conversions on iOS after adopting a PWA. The PWA made the app more accessible and user-friendly, leading to a 104% increase in new users.


British retailer Debenhams saw a 40% increase in revenue from mobile devices after launching a PWA. The new app reduced purchase time significantly and improved overall conversions by 20%.


Indian eCommerce giant Flipkart experienced a 70% higher conversion rate and a 40% higher re-engagement rate after introducing Flipkart Lite, a PWA designed to offer a better user experience.


In summary, a regular web app is essentially a website accessible via a URL, offering features that make it look and feel like a native app but without the ability to be installed on a device. On the other hand, a Progressive Web App (PWA) is a more advanced version of a web app that not only offers a native app-like experience but can also be installed on a device. This makes PWAs a more potent option for businesses looking to provide an excellent customer experience.

By opting for progressive web app development, businesses can create lightweight, secure, and feature-rich web solutions that are easy to use and install. With PWAs, businesses can increase user engagement, improve retention rates, and ultimately boost their revenue.

1. What exactly is a Web App?

A Web App is basically a website that you can interact with. Unlike static websites that just show you information, web apps let you do stuff — think about webmail, online shopping, or social media sites. They run in your web browser, like Chrome or Firefox, and don’t need to be downloaded from an app store.

2. So, what’s a Progressive Web App (PWA)?

A Progressive Web App (PWA) is like a supercharged web app! It combines the best features of web apps and native apps (the ones you download from an app store). PWAs can work offline, send you push notifications, and even load super fast. They’re designed to give you a more app-like experience right from your browser.

3. How do Web Apps and PWAs differ in terms of performance and speed?

Great question! Web Apps rely heavily on having a good internet connection. If your connection is slow or spotty, the app might lag or not work well. PWAs, on the other hand, use something called service workers to cache resources. This means they can load quickly and work smoothly even with a bad or no internet connection.

4. Do I need to install a PWA like I do with a native app?

Not really! One of the coolest things about PWAs is that you don’t have to go to an app store to download them. When you visit a website that offers a PWA, your browser (like Chrome) might prompt you to “Add to Home Screen.” If you choose to do this, the PWA will look and feel like a regular app on your phone or tablet but without the hassle of a traditional app installation.

5. Are there any security differences between Web Apps and PWAs?

Both Web Apps and PWAs can be secure, but PWAs have an edge because they use HTTPS. This ensures that the data exchanged between your browser and the server is encrypted, making it much harder for anyone to intercept or tamper with your data. Plus, service workers in PWAs can only operate over HTTPS, adding another layer of security.

6. How are updates handled in Web Apps vs. PWAs?

Web Apps are updated by developers on their servers, so you don’t need to do anything — the next time you load the web app, you’ll get the latest version. PWAs also update automatically, but they do it more seamlessly. Thanks to service workers, PWAs can update in the background, ensuring you always have the most recent version without any interruptions.

7. Which one should I choose for my project, a Web App or a PWA?

It really depends on what you need! If you want a simple solution and your users will always have a stable internet connection, a Web App might be enough. But if you want something more robust that works offline, loads quickly, and provides a better user experience (like push notifications), then a PWA is the way to go. PWAs are especially great if you want to reach users on mobile without the hassle of app store submissions and downloads.
