How web applications are developed: the main stages of the process

The Information Commissioner’s Office (ICO) is issuing a reminder to all app developers regarding the paramount importance of safeguarding users’ privacy, following its examination of period and fertility apps.

Some users often need clarification on the concepts of a web application compared to those of a mobile application. These are different digital products with various features and characteristics. They also differ in their approach to development.

Web applications are interactive sites where you can perform specific actions and operations. A striking example is an online store with the functions of adding goods to the cart, viewing characteristics, selecting product parameters, and paying for them online. Such web projects are in high demand in the UK. To get a high-quality, functional product, you must use reliable and proven web application development services to achieve your goals.

The web development process itself consists of several main stages. Let’s talk about them in more detail.

Technical task

To understand the final product, it is necessary to obtain a list of requirements and develop the corresponding technical specifications. The initial information must be studied at this stage, and a list of mandatory and additional requirements must be drawn up.

Since specialized companies usually conduct web development, they sign an agreement between them and the clients. It specifies all the conditions and details of cooperation.


At the next stage, developers must create a future web application prototype. To do this, they need to think over a straightforward and convenient interface and all other project details. The result should be a working prototype capable of displaying all the main functions and capabilities of the site. Based on this project, it will be easier and more efficient to turn the web application into a full-fledged working product in the future.


The third stage of creating a web application is design development. To complete the tasks at this stage, it is necessary to consider the already developed structure, logic, preferences, and customer wishes. The result is a full-fledged UX/UI design of the project.

The design makes it possible to understand what the project will be like when work on it is completed. At this stage, the customer can make necessary adjustments to the order, present additional requirements, or change color preferences. Since the client sees all the details of his order, he gets an excellent opportunity to clarify the details.

Layout and development

The next step for specialists in creating a web application will be the layout of the interface and the development of its server part. These stages are called frontend and backend.

The main task for experts is to create a fully functional version of the project. Once completed, you can see how the application will work and what it will look like.


Since the application can still be called “raw,” you need to ensure that it works correctly and performs all the functions laid down by specialists and provided for in the terms of reference.

At the testing stage, developers need to check the functionality of all functions, identify possible errors, eliminate them, and optimize the main processes and capabilities of the digital product. The output is a ready-made web application that has passed the necessary tests and can be implemented.
