How does a web application work?

Understanding the inner workings of web applications is like peering behind the digital curtain. At their core, web applications follow a client-server model, which is key to their functionality.


  • Web Browser: You interact with a web application through a web browser like Chrome, Firefox, or Safari. The browser acts as the “client” in this setup.
  • User Requests: When you type a web address or click on a link, your browser sends a request to the web server hosting the application.
  • Display: The browser receives data from the server and interprets it. This data often includes HTML, CSS, and JavaScript files.
  • User Interaction: As you interact with the web app, your browser sends requests to the server based on your actions, like clicking buttons or filling out forms.


  • Web Server: On the server side, a powerful computer called a web server stores the web application’s data and logic.
  • Processing Requests: When the server receives a request from your browser, it processes the request, retrieves data if needed (from a database, for example), and performs any required calculations.
  • Generating Responses: The server then generates a response, typically in the form of HTML, which includes the content you see on the web page.
  • Sending Data: This response is sent back to your browser, which displays it as a web page. Your browser and the server may continue to exchange data as you interact with the app.

Real-Time Interaction

What makes web applications dynamic is the continuous back-and-forth between your browser and the server. This real-time interaction enables web apps to respond to your actions instantly. For instance, when you comment on a social media post or submit an online form, the server processes your input and updates the page without requiring a full page reload.

General, web applications use this back-and-forth communication to create the interactive, responsive experiences we enjoy online. It’s like a digital chat that brings the internet to life.

Difference between web applications and other types of applications

With Website

The main difference between web applications and websites lies in their functionality and interactivity:

  • Static vs. Dynamic Content: Websites primarily contain static content that doesn’t change frequently. They are often informational and provide text, images, and links. Web applications, on the other hand, are dynamic and interactive. They allow users to perform tasks, submit forms, interact with databases, and receive real-time updates. Examples of web applications include Gmail, Facebook, and online shopping carts.
  • User Interaction: Websites are designed for users to consume information passively. Visitors can read, view, and navigate through the content but generally cannot actively interact with it beyond clicking links. Web applications, however, require user input and interaction. Users can create accounts, post content, send messages, and perform various actions within the application.
  • Purpose: Websites typically serve to inform and present information about a business, organization, or topic. They are like digital brochures or publications. Web applications, on the other hand, serve to provide a service or perform specific functions. They are task-oriented and often involve user accounts and data processing.
  • Technical Differences: While both websites and web applications are accessed through web browsers, web applications involve more complex programming and server-side processing. They require databases and server interactions to deliver dynamic content. Websites are simpler in structure and function.

With Native Apps

Native apps and web applications (web apps) are two different approaches to developing software for various platforms. Here are the key differences between them:

  • Platform-Specific vs. Cross-Platform: Native apps are built for a specific platform or device, such as iOS or Android, using platform-specific programming languages (Swift/Objective-C for iOS, Java/Kotlin for Android). In contrast, web apps are platform-independent and can run on any device with a compatible web browser, making them cross-platform by nature.
  • Installation: Native apps need to be downloaded and installed from app stores (e.g., Apple App Store, Google Play Store). Users must go through an installation process, which includes granting permissions. Web apps, on the other hand, are not installed on devices but accessed through web browsers. Users simply navigate to the web app’s URL.
  • Performance: Native apps often offer better performance and responsiveness because they are optimized for the specific platform’s hardware and software. They can access device features like GPS, camera, and sensors directly. Web apps, while improving in performance with technologies like Progressive Web Apps (PWAs), may still have limitations compared to native apps, especially in resource-intensive tasks.
  • Updates: Native apps require users to manually update them when new versions are available through app stores. Web apps are automatically updated when the user accesses the latest version through their web browser. This can be advantageous for developers as they can ensure users are always using the most up-to-date version.
  • Distribution: Native apps are distributed through app stores, making them discoverable to users searching within these platforms. Web apps, on the other hand, rely on marketing and promotion to attract users to their websites. They can also be added to the home screen on some devices for easier access.


In this article, we learned that web applications are dynamic, interactive tools that transcend mere information dissemination, enabling users to perform tasks and engage with content seamlessly. Besides, we explored their benefits, such as accessibility, real-time collaboration, and cost-efficiency, and compared them to websites and native apps, uncovering their unique strengths and applications.

Now, armed with a deep understanding of what is a web applications are and how they function, you’re ready to harness their transformative potential in your digital endeavors.
