What Is a Web Application?

Web application development is the process of creation an application for which develpes it both, client and server sides, but still makes it possible to access through a web browser, without downloading.

A web application is an interactive application that uses web development technologies to create a platform that users can reach from any browser on any device. Web apps appear in online shopping, banking, email services, and booking software, to name just a few places where you’ve seen them.

A web app has the front-end and back-end development technologies that all software applications have. In many ways, they are like websites. The two share some characteristics, but there are key differences.

One difference is how they are built. Most experts in website application development use standard coding languages like Python and Ruby to build the back ends of website apps. However, they will use separate languages, including JavaScript and HTML to build the front ends.

Web apps use more dynamic, innovative technologies than standard websites use. They are geared to a mobile audience that demands access from any browser and any device. When building a custom web app, a developer will use client-side and server-side programming to create an app that works on any browser.

A Web App Is Not a Website

The confusion between a web app and a website is understandable, and it might seem overly technical to get into the details of how they differ. Understanding these differences is important, however, and it’s foundational to knowing how a web app works and what it can do for you.

To use one example you’re probably familiar with, you may have noticed that shopping from a store’s app or banking from your bank’s mobile app is more functionable than scrolling and clicking on a static business website. That just lists necessary information, but have no interaction with you, except only receiving your basic personal data, like email adress. It may look good, but it just sits there. That an app you enjoy using, by contrast, is responsive, fast, and intuitive. Because, the primary focus in web app is on different kinds of user interaction and the user experience (UX).

Web application development uses website technologies, but they use them differently. A traditional website may be informative, and it may collect basic information about its users for limited functions like online shopping, but it doesn’t offer a fully engaged experience. A web app gives you immediate engagement with a product or service.

How Web Apps Differ from Mobile Apps

That brings us to your logical next question: Is a web app the same as a mobile app?

Here, the technical difference involves the difference between a mobile app and a native app.

A native app is one that is native to a specific operating platform. When you download an app to your device, you must choose an app that’s designed for either Android or iOS. You buy them or get them free from a platform-specific store and store them on your phone.

These apps may be great, but you can only use them on your mobile device. They have limited functions and use valuable storage space on your phone. These apps are also costly and time-consuming to build.

A web app, on the other hand, is more flexible and dynamic. As its name implies, it works on any device that has web browser and independently of a specific platform. Because you use a browser to reach it, it doesn’t take up space on your device.

Advantages of Web Apps

Today’s customers are very picky, because of a huge range of choice they have, so if they not satisfied with an app on some point, if it doesn’t keep them engaged, they just go for another one. A high-quality user experience and customer engagement are key to creating conversions and sales. But let’s see what else does we have here in favor of web apps.

They’re Portable

A web app is highly portable because it’s accessible from any device. Users can reach them through a phone, tablet, desktop or laptop. They are multi-platform applications that work equally well on every operating system and every device.

They Don’t Take Up Space

Although modern smartphones have a lot of storage, customers still want to avoid overloading them with excessive bloatware. With web apps, space is not an issue because they’re not tied to a single device. Exception is PWAs, but its extremely fast downloading and small size not comparable with common apps. They also don’t require the constant, annoying updates that other apps do.

They’re Cost-Efficient

Building a web app requires specific skills. If you are working with a web application development company, you are getting high-level web application development services. Do you plan to put your app on iOS, Android or both? If you’re building a native app, you will have to build two versions of it.

A web app is easier to build, easier for your customers to use and easier on your time and budget than a native app. You only have to create one version because it will work anywhere.

The next question is, what type of custom app do you need?

Types of Web Applications

Web Application differs depending on the way it builds and the way it use. Each type looks and performs differently.

From coding side it can divided into two parts:


These apps side use front-end development to create apps that are high in UI and UX. These apps side focused on powerful, client-oriented functionalities.


A Server-Side is equivalent to back-end development. These apps manage large databases, servers, application programming interfaces (API) and other elements of an application. Server-side rendering can processing static content and huge amounts of data.

By the type of development web applications distinguished by client-side and server-side. And Every Web Application consists of both, the client and server sides. Where the Client is a web browser (Safari, Firefox, Chrome, Edge, etc.), and the Server ia actually a located remotely server that processing all requests and send them back to a web browser.

From the usage side, there is much more types and subtypes:

Static Web Apps

These apps get their name from their design, which lacks flexibility and movement. Creators of these pages use HTML and cascading style scripts (CSS) to create web pages that are not interactive.

In general, such web application return to the client side the same as it was stored on the server, meaning that there no changes were made to the content in static application in a midtime.

Static web pages offer no personalization or interaction. That said, static web pages are useful for industries that don’t require extensive customer interaction. If you just want a site that customers can look at without interaction, they will work. A static web page is a good choice for an artist portfolio, company contact list, restaurant menu, digital resumes and other informational sites.

Dynamic Web Apps

If your first thought is that dynamic web apps are the opposite of static web apps, you are correct. These apps have highly interactive features that include both client-side and server-side functions.

So why exactly dynamic web app differs from static one? It short, it has additional steps, an interaction with database where stores all data and related content, before it sends answer to web server and turns it back to the client side. These sites display their content according to the user’s prompts. They are usually built with a content management system (CMS) that facilitates customer interaction.

dynamic web app scheme

A dynamic web app allows you to interact with the website. You can sign up, watch videos, request more information or learn more about the company or product. Any site that lets you create an account, post reviews, make comments or sign up for emails is a dynamic website.

Technically, any app that isn’t static can be defined as dynamic, but there are other variations that we’ll discuss in the following web app descriptions.

Single-Page Apps

Single-Page Apps (SPA) have the advantages of both client-side and server-side apps. These apps get their name from their single-page display. A SPA constantly rewrites its own web pages with new data from a web server. Some web app development service providers complain that SPAs can be slow, but you can give them a speed boost by incorporating dynamic routing through JavaScript, React and other frameworks.

A bright example of single page app is Gmail. Gmail allows easily to check, read and send emails from any device and any location, and have you eve noticed that everything happen on the same page? So, yeah, it is a SPA.

Ecommerce Web Apps

Ecommerce sites allow you to buy and sell online. At a minimum, these sites need ordering, shipping, and payment processing web apps. Even these simple functions, however, require technically sophisticated web application services. These web apps help manage large databases, arrange shipping, create customer-specific incentives, and process hundreds of transactions daily.

Most ecommerce sites need interfaces that strongly resemble the native app experience. This allows customers to have the same shopping experience no matter what device they use to shop, book or buy.

Examples of eCommerce web apps include some of the most popular websites, like Amazon, eBay, NextDoor and Posh.

Portal Web Apps

Web Portal app is a platform that provide different level of acess for different audiences, while providing a high level of security for each one.

Different user roles also requires specific user experience design, content and interaction way. Such web applications are mainly popular among business which project requires customization for every user role or specific customer groups.

A web portal is an area that users can enter to perform a specific function while they’re on a website. And the main aspect of Portal web application is security level provided for every entry level.

The most common use of a web portal is the payment processor on a commerce site. When you make a payment, the website takes you to a portal belonging to your credit card company or PayPal account. You enter your information in the web portal, which keeps your personal data secure while allowing payment to go through. Once the payment finishes, you return to the website.

Progressive Web Apps (PWA)

If you want an app that combines the best of all these other apps, a PWA is an excellent choice. These apps are the latest arrival on the web app scene, and they are a true innovation in web application development services.

A PWA combines the best features of both native and mobile apps. With one-click access and availability from any device, these apps are highly responsive, intuitive, and secure.

A PWA is a traditional website in mobile app packaging. While not as interactive as a traditional mobile app, it is more accessible and dynamic than a traditional website. Using a PWA is very similar to the experience of using the best native apps. Our custom web application development company specializes in building these innovative apps.

Most notable examples of Progressive Web Apps are AliExpress, Twitter Lite, Pinterest.
