Chances are that you did access a web application at least once ever since starting to use the Internet but never noticed it, and now you want to develop one for your own business but don’t know how and where to begin. So, if this is a problem that might bother you, let us give you a quick introduction to web applications!

In this article, we will take you through 3 parts:

  • What is a web application?
  • How does a web app work?
  • Pros and cons of using a web application

What Is a Web Application?

A web application seems a bit similar to a website, nevertheless, the only thing they share in common is running on web browsers. Basically, a website merely shows and focuses on content such as images, texts, and links, and most of the time, you can only go from one page to another without any other actions to do. A web application, on the other hand, offers you specific functions and features to interact with.

So, this blog is a website. is a web application (you can comment, like, or share posts, etc. here). is a website. is a web application (you can zoom in on the photos, order items, and make purchases here.

At the moment, a lot of desktop apps and software have their own web application version to optimize their user experience. For instance, you can easily access Slack on Chrome or Safari instead of downloading the whole 67-Mb package.

7 Types of Web Apps

In this part of the article, we’ll talk about the different kinds of web app development. Choose the option that works best for you and meets the needs of your business.

1. Static Web Applications

The content of a static web application is sent to the end user’s browser in a way that doesn’t change if JavaScript is changed on the server. Static web applications are easy to make on the web, but they are not as adaptable as dynamic web applications.

For static web app development, you need to know HTML and CSS, plus jQuery and AJAX to make things easier. Most of the time, rich websites that deliver dynamic content by using technology in the browser instead of on the server are “static web apps”. This can include sites that don’t change much, like a company’s website. These are great for use in book publishing businesses because they work without an internet connection and don’t need software from a third party.

2. Dynamic Web Applications

A dynamic web application creates data in real time based on what the user asks for and how the server responds. Let’s look at an example of a dynamic application to help us better understand how it works.

When you sign in to your Netflix account, the service will show you movie suggestions based on movies you’ve seen. If you choose to watch a romantic comedy, Netflix will give you more suggestions for romantic comedies.

Most of the time, a control panel called CMS is used to manage these apps. From this panel, app administrators can change the text and graphics inside the app. Using a wide range of web languages, it is possible to make online apps that change over time. PHP and ASP are the most common languages for organizing information. This is because they are much easier to understand than other languages.

3. Single-page Applications

A single-page web app gives you a single web document instead of a whole new page. JavaScript programming interfaces (APIs) like Fetch and XMLHttpRequest can help change the content of a single-page web app. 

For example, when you use a web app to check your email, the headers and sidebars do not change. Single web apps are much faster than standard web apps because the logic of the program is implemented directly in the web browser instead of on the web server.

Services like Gmail, PayPal, Google Maps, Airbnb, and many others like them.

4. Multi-page Applications

It is a type of web application that has more than one page. It also reloads the whole page when a user goes to a different page within the application.

For example, if you want to buy a laptop from Amazon, you have to click on the laptop you want to buy. When you add a laptop to your shopping cart and then click the “next” button, the online store will take you to the next page. After that, click “Buy,” and you’ll be taken to a page where you can pay with your card.

Aside from Amazon, organizations like Trello and eBay also have online applications with more than one page.

5. eCommerce Web Applications

eCommerce web apps let people buy and sell things over the internet. Integration of payment and transaction processing, a user-friendly interface, adding order carts, posting and deleting products, and having a user-friendly interface all make eCommerce web applications complex, hard to design, and hard to manage.

eBay, Amazon, and Walmart are all examples of eCommerce sites that also focus on web app development

6. Portal Web Applications

A portal app is a type of website that lets you get to many different sections and categories from the home page. This page has a lot of information, such as about emails, chats, forums, user registration, and other similar things. These apps usually have a lot of different parts and categories, and they usually need you to log in from a safe place.

Portal applications let users customize how they access and move through the site based on their needs. There are many different kinds of portal applications, such as university portals, portals for patients, and portals for clients.

Coursera and Udemy are both well-known educational portal web apps that let people all over the world learn from a distance. These programs include everything from classes to help you learn new skills to college degrees.

7. Progressive Web Applications

Even though they are web apps, these programs act like native apps. You can save them to your mobile device and use them even without connecting to the internet, but they don’t need the same technologies as native programs.

PWAs are built with common web technologies like Javascript, HTML, CSS, and others. The main goal of these kinds of apps is to make online apps more flexible, even when the internet connection is slow.

PWAs are used a lot, and Starbucks, BMW, and Spotify are just a few well-known examples.

How Does a Web Application Work?

To make this easier, let me tell you a story.

One morning, John feels that he must go online and see if his favorite singer – Rihanna – has released a new album. So, he accessed Twitter searched the word “Rihanna” and read all the tweets related to this singer. 

Basically, that’s how this web app works under the eyes of a user. However, let’s take a look at some technical details.

First, John accesses Twitter via his browser, which could be Safari, Chrome, or whatever he prefers. This action triggers a request to the web server over the Internet.

Then, the web server forwards John’s request (in this case, it’s to access Twitter) to the web server. And the web server will perform that task. 

After that, the web app will send the result back to the webserver.

The final step is that John’s requested information will be delivered to his devices and appear on the screen.

Advantages and Disadvantages of Using a Web Application to Assist Your Business

1. The 5 Advantages

1. Flexibility

Since a web application can run on various browsers, users don’t need to worry about compatibility. You can just open it on Chrome, Safari or Firefox, etc. and interact with that site without worrying if your current OS or device could handle this application. 

In short, it does not matter what your users are using, the web application is still operated well (of course if your web application is developed properly).

2. Save space on disks

It’s a fact that you don’t even need to install such software on your computer or phone thanks to the availability of the cloud. This way, users don’t need to waste any space on disks to perform activities that could easily be done on browsers.

3. Does not need to be approved by app stores

As we have mentioned in Android App Development Guide: A Comprehensive Guide”, the submission stage takes a lot of time and is kind of complicated. As a publisher, you have to sign code on the AppStore and the Play Store and follow their rules and regulars if your product is a mobile app. Nevertheless, when it comes to a web application, you can just publish it without any need for approval. 

4. Users can access such a product easier

Another advantage of web applications is that your users can open your product anywhere, anytime. Thanks to this convenience, your potential customers won’t have to spend their precious time and effort to experience your products/services. 

At the same time, every user will be on the same page, or more exactly, they will all use the newest version of your software and there is no need to download it.

5. Reduce cost

Cost is one of the most important factors that make businesses pour their little budget into developing a web application. With web apps, you don’t have to develop your software for various operating systems like macOS, Windows, or Linux. In other words, this is a one-for-all application. As a result, the development and debugging stage will not be a big issue.

On the other hand, your design team doesn’t have to customize the UI design for each device, OS, etc.

The 3 Disadvantages

Along with all the good things, there are always some downsides. Businesses should consider these to decide if they should develop a web application.

1. Too dependent on the internet connection

Due to the fact that users must use a browser to access your product, connection loss will be a common issue for any web application.

However, don’t be so desperate since, at the moment, the amount of time people spend using the Internet is increasing rapidly. According to DataReportal, a person uses the Internet for an average time of 6.5 hours/day.

2. Security

Cloud is a perfect place to host your web app, nevertheless, the risk of data breaching is increasing as well. According to Edgescan, in 2018, there were 19% of the websites tested faced the vulnerabilities of being attacked. And this was the result of poor-quality coding. Furthermore, it was reported that the possibility of exposure to vulnerabilities would easily happen to 79% of web applications. This ratio increased from 70% in 2017. Such a bad piece of news.

However, approaches such as SSL enforcement could be your savior in this situation.

3. Speed

Again, the cloud might be the reason here, because of it, your web application is likely to run slower than other types of applications that are hosted on a server locally.

Apart from the cloud, this may happen due to the slow server and loading, low bandwidth, DNS issues, and network connectivity.
