What Are Web Applications and How Do They Work?

  • 20.03.2025.

Web Applications: A Key Component of Digital Development
Web applications are interactive programs that you can access through an internet browser without the need to download or install them on your device. They run on remote servers and use the internet to transmit data, allowing you to use them on any device—computer, tablet, or smartphone.

Examples of web applications include email services like Gmail, social networks like Facebook, online banking, and various online collaboration tools such as Google Docs. Their key advantage is that they are always updated, easily accessible, and often allow multiple users to work on the same data simultaneously.

In short, web applications are modern software tools that simplify everyday tasks and provide access to information and services from anywhere in the world, as long as you have an internet connection.

Key Differences Between Web Applications and Websites
One of the most common questions in digital development is: What is the difference between a website and a web application? Let’s break it down simply.

Website vs. Web Application
A website is a static, informational form of presentation. Think of it as a bulletin board where you can browse information, but there is no direct interaction with the content. Users can only view the content without receiving responses from the server. For example, a website can display information about your services but does not allow users to perform actions within it.

On the other hand, a web application is more dynamic and complex. It allows users to perform specific actions. For example, if you use a web application for tourism, it enables you to manage reservations and perform various tasks such as filtering options or booking accommodations.

Unlike traditional software that runs on a computer or mobile device, web applications do not depend on specific operating systems (iOS, Android, Windows, Mac, Linux). They work through browsers like Chrome, Firefox, Opera, Brave, or Edge. This means that no matter which device you use, you only need an internet connection and a web browser to interact with the server. If you lose internet access, data can be temporarily stored in the browser’s memory and automatically synced to the server once the connection is restored.

Types of Web Applications
Web applications can be divided into several categories, but here are three of the most common ones:

1. E-commerce Applications
E-commerce applications allow buying and selling products online. One of the most famous examples is Amazon. These applications provide users with a secure and seamless online shopping experience.

2. Social Media Applications
These applications are designed for real-time communication. Users can post personal updates, share media, and interact with others' posts. Examples include Facebook, Instagram, and Twitter.

3. SaaS (Software as a Service)
SaaS applications provide online access to various software tools. Google Docs is one of the best-known examples, allowing users to edit Word documents, presentations, and Excel spreadsheets directly from their browser.

There are also other types of web applications, such as CRM and ERP systems:

ERP (Enterprise Resource Planning) – These systems help plan resources and manage company data efficiently. While they may not be widely known among general users, ERP systems are widely used in industries like hospitality for optimizing resource management and cost efficiency.

CRM (Customer Relationship Management) – CRM systems track and analyze customer data, sales, marketing, and customer support. Salesforce is one of the most well-known CRM platforms, offering sales automation, personalization, and integration with other applications.

How Long Does It Take to Develop a Web Application?
One of the most frequently asked questions by clients is: "How long does it take to develop a web application?"
In general, web application development can take up to 12 months, depending on the complexity of the requirements. If you already have an existing example, the development process is faster since the team can follow a clear guideline. If you do not have a concrete example, the process may take longer as your idea needs to be turned into a fully functional product.

Cost of Developing a Web Application
The cost of developing a web application can range from €5,000 to €100,000 or more, depending on the required features and complexity. While the cost may seem high, the investment is justified since web applications often require data optimization, system synchronization, and ensuring seamless integration between different components.

The key question you should ask yourself is: "How can I improve my business, optimize processes, and reduce costs?"

Conclusion
Think about how you want to advance your business, speed up processes, and simplify daily tasks. Digitalization can significantly enhance efficiency, eliminating the need for manual record-keeping or complex report generation. If the answer is yes, investing in a web application is a worthwhile decision. It will save you time and resources while allowing your business to focus on more important tasks.
