Are you searching to create an application that works almost everywhere: computers, Android phones, iPhones, and Tablets?.

And that too without a headache to launch it on either the Play Store or the Apple Store?

If the answer is “YES”!

It’s your time to build a progressive web app (PWA).

But the question is, what is a PWA, and how to build a progressive web app (PWA)?

PWA is a website that can run in a browser but works exactly like a native mobile app. To create a PWA, you need to opt for market research, select the right set of features, design the app, select the tech stack, test the app, and then launch it in the market.

In this guide, we have covered it all from the concept, reasons to select PWA, features, process, tech stack, limitations, and even use cases.

Without any further ado, let’s get started.

What is a Progressive Web App (PWA)?

A progressive web app (PWA) is a website that runs in a browser but works, looks, has features, and even feels like a native mobile app. You can build a PWA by creating standard web technologies such as HTML, CSS, and JavaScript.

This PWA can be installed on your device, works offline, and is even helpful for sending push notifications, offering a fast, app-like experience without even downloading it from an app store.

Well, as per the defined image, you might be clear about PWA, but what are the benefits of PWAs?

But, when you create a mobile app, the next question is what the key reasons are to choose a PWA over other apps.

Why Choose a PWA Over Other Apps?

The key benefits of a progressive web app are a native-like experience, cost and time efficiency, offers offline usability, automatic updates, and no app store constraints.

Let’s discuss the complete set of benefits of a progressive web app:

1. Have Offline Mode

The progressive web apps do offer offline functionality with the help of service workers that do acts like a background proxy.

When a user opens an app online, the service worker intercepts the network request and caches your core files using the Cache API and saves data via IndexedDB.

2. No Installation or Manual Updates Required

A PWA does not require any manual installation or updates because it is essentially an advanced, installable website.

Additionally, these apps operate directly through web browsers. Here, you eliminate the manual updates because they run instantly via a browser URL and by bypassing the app store.

3. Low on Data

One of the reasons to create a PWA is that it uses much less data than native apps or even standard websites. These apps achieve this by downloading only critical elements during initial use and by relying on smart caching.

This feature is just like one can read WhatsApp messages even without any internet connection.

4. Improves Performance

The implementation of PWAs dramatically boosts performance by using service workers. This app is aimed at delivering a high-performance website with an app-like user experience.

Through PWA, you can use technologies such as HTML, CSS, and JavaScript, which are helpful to cache the essential assets locally by eliminating redundant network requests.

5. Automatic Updates

With the help of service workers, you do not need to update the app manually every time; it will automatically update based on the current updates available.

Here, the app silently checks for updates, performs the background checks, and then syncs the app directly, allowing the app to provide updated data, which increases overall user experience.

6. Cost and Time Efficiency

PWAs apps do offer massive cost and time savings through eliminating the overall need to replace the separate iOS, Android, and desktop apps with a single codebase.

It saves the total cost, as you do not need to write code, and you share 30% revenue by giving a commission to be on either of the platforms.

But why is PWA so effective that its market size was estimated at USD 2.08 billion in 2024, that is projected to reach USD 21.24 billion by 2033, and is growing at a CAGR of 29.9% from 2025 to 2033?

Well, because of its features, and the nailed experience that it provides to the users.

Want to know more about the PWA? Let’s get ahead with what makes a progressive web app effective.

What Makes a Progressive Web App Effective?

Well, the answer is “features”. The features of PWA make it different from web apps and mobile apps.

Here is the list of features to include in a progressive web app:

1. Offers Reliable and Offline Capabilities

PWA delivers reliable, offline-first experiences via service workers. These workers act as a network proxy and background scripts.

The app has a progressive nature, and it works for every user, regardless of the browser choice. PWA apps are reliable and fit any form factor.

2. Instant Loading

PWA does deliver instant loading by using the app shell architecture. These technologies even bypass the network completely on repeat visits.

This app intelligently stores the core elements locally on the user’s device. It does data fetching in the background and instantly delivers the results.

3. Add to Home Screen

Progressive web apps can be added to the home screen and are simple to use, performing the function just like a native app.

The majority of modern browsers do support the features of mobile Chrome, and by adding the opera for home screen. Through using the web app manifest file, PWA tells the browser how the app should look, what app icon it should present, and all other determinants.

4. Push Notifications

PWAs do offer push notifications via a combination of three web technologies, including the push API, the notifications API, and a service worker.

Push notifications allow the servers to send alerts related to using the device even when the PWA or browser is closed, bridging the gap between the web and native mobile apps.

5. Secure

Mobile app security is an indispensable and built-in feature of PWAs that protects the user data and even prevents cyberattacks.

This PWA app offers mandating HTTPS encryption, which isolates the background scripts, and even utilizes the browser-level permissions.

6. Easy to Discover

Easy to discover acts as a feature of PWA because it enhances the search engine visibility, and can index its pages, as well as content. Additionally, the PWA utilizes a JSON file called the web app manifest, which helps discover the app quickly.

PWA is directly exposed to the open web, and even allows users for installation on their devices.

7. Responsive App

The features of the PWA app are responsive and use a single codebase that automatically responds even in a flaky network environment.

These apps have a faster response time to the user’s interaction and are more engaging to the users than responsive websites.

Following the features to include in the complete process of progressive web app development, let’s get ahead with the process of PWA app development.

How to Build a Progressive Web App?

You can create a progressive web app by including the right process that begins with the market study, selecting the features to include in the app, identifying the technologies to include in the PWA, performing app testing, and then launching the app on the desired platform.

Here is the complete step-by-step process to build a progressive web app:

Step 1: Evaluate Your App Requirements

This is the first step, where you conduct a comprehensive app market research by validating the idea, sizing the market, and understanding the demands of your customers before writing a single line of code.

Here you should perform:

• Evaluate the user requirements by combining the direct user research (interviews, surveys, and observations) with the behavioral analytics.
• Perform the competitive analysis by compiling a feature and reviewing matrix.
• You should use intelligent tools to track competitors’ downloads, along with their monetization models.

Step 2: Selecting the Right Set of Features

Now, you should select the appropriate set of features requiring balancing the user needs, technical browser capabilities, and the core business goals. It prioritizes core functionality over “native” bloat.

Here’s how you need to select the right set of features for your PWA app:

• Identify your core building blocks by service workers, web app manifest, and HTTPS protocol.
• Comply with the user’s needs, such as blending the functionality with the native app-like behaviors.
• Balance the native-like functionality with performance, and prioritize core essentials such as installability, offline caching, and responsive design.

Step 3: Building the UI/UX

Under this step, you should select the right app design for a PWA, which requires a mobile-first, native-like user experience that is coupled with the app-shell architecture. Here, you should balance a native-like app experience with web accessibility.

Here’s what you should include while creating a UI/UX:

• Build an intuitive user experience that has a cross-platform nature, great UI, and UX for both mobile devices and desktops.
• Create an attractive home screen icon
• Add the custom splash screens and show interaction.

Step 4: Identifying the Set of Technologies and Building the Architecture

Step 5: Develop the Core PWA

In this step, you combine the design with the technologies and architecture selected. Here, you should install the web app manifest, implement a service worker, ensure secure hosting, and test the complete app.

Here’s what you need to consider:

• Web app manifesting: it is a JSON file that offers metadata browsers a facility to install a website.
• Implementing a Service Worker: While creating a PWA, you should register the service worker file in your main client-side JavaScript.
• Ensure Secure Hosting: Under this step, you should guarantee that all traffic is encrypted and your server environment is properly configured.

Step 5: Testing the Complete App

In this step, you should test PWA during the development process. Here, you must validate the features of PWAs, such as offline capabilities and service worker lifecycle hooks, along with the installation criteria.

Here’s what you need to perform during the app testing:

• Opt for the functionality testing, including the core flows, input validation, database & state, and deep links.
• Perform a user interface and usability testing.
• Conduct a network and interruption testing.

Step 6: Launching, Monitoring, and Maintenance

Now, in this step, you can launch the PWA for your actual users. Make it interactive and easily installable as per the preferences of the users.

You should perform:

• Launch the website, or you can say PWA
• Monitor it thoroughly.
• Opt for mobile app maintenance for the complete PWA app.

Now, with this complete process, you might want to have a look at the right tech stack to include in a PWA. Well, in the following section, let’s get it learned.

Tech Stack to Include in a Progressive Web App

The key technology stack to include in the PWA relies on the standard web languages paired with specific tools and comprises HTML5, CSS3, and JavaScript (ES6+).

Here is the complete table defining the list of technologies to include in a progressive web app:

With the complete list of technologies to include in the PWA, there might be a certain list of challenges that your PWA might face.

Let’s learn more about the list of limitations for PWA in the following section.

What are the Limitations of a Progressive Web App?

PWA is an effective strategy for cost savings, but they have major drawbacks, such as offering limited access to device hardware and no presence in the traditional app store.

Let’s discover the complete details of the disadvantages of PWA:

1] Poor iOS Integration

Bad iOS integration blocks access to device features, background tasks, and the system integrations that native iOS apps can use freely.

The lack of app store discoverability, absent automatic install prompts, and aggressive memory management that even leads to app reloads and data purges.

2] Limited Access to Device Hardware

PWAs run inside a browser’s security “sandbox”; they cannot fully access low-level device hardware. It leads to advanced connectivity issues, camera controls, biometrics, and background processing.

These apps operate inside a browser’s security sandbox rather than having OS-level access.

3] No Presence in the Traditional App Store

PWA has no presence on the traditional app store, which can be one of the important limitations to consider, through acting as a supercharged website rather than compiled software packages.

Lack of presence in either of the stores limits discoverability, hinders monetization, and restricts complicated native hardware capabilities.

4] Slow Loading Time

PWA relies heavily on the browser’s processing overhead and JavaScript execution. An inefficient JavaScript execution can block the main thread.

If the initial load time is too long, the users may abandon the app before they even experience its features.

Following the limitations of PWA, you should evaluate the diversified use cases, and even examples of the same.

Use Cases of Progressive Web App
