Web application development: main stages

Who is developing

Hiring your own team to develop an application is time-consuming and expensive. According to Indeed.com , the cost of hiring one employee starts at $4,000, not including salaries. To save money, you can turn to freelancers for web applications. But often this is not the best solution. A full-fledged application requires a team of analysts, designers and programmers, and it is unlikely that one person will have all the knowledge at once. And if you hire several freelancers, you will have to take on the work of a project manager. So the easiest way to develop a website for a company is to contact a studio where an experienced and well-coordinated team will work on the project. 

The process of creating a web application involves:

  • Analysts – they help to better study the niche, identify the target audience and understand what functionality is necessary for success in the market.
  • UX/UI designers. They think through the user journey and create prototypes. Then the site design is drawn directly : buttons, icons and other interface elements.
  • Front-end developers. They transform the website design (layout) into a working website: they animate buttons and blocks using code.
  • Backend developers. Responsible for functionality: connecting databases, payment systems, building the internal logic of the application.
  • Testers. They check the application for bugs and help release a product to the market that works without errors.

Development stages

Each specialist is responsible for their own stage of  web application development company . However, the stages and their sequence may vary slightly from studio to studio. We will talk about how the process works in Purrweb and how a business owner will need to be involved in the process.


It’s worth going to the studio when you already have a ready-made idea for an application and a rough understanding of how it will function. To do this, the entrepreneur must have expertise in the chosen industry.Analysts will figure out what niche your product can occupy in the market, which target audience is more profitable to target, what functionality these people need, and what monetization model to choose. 

Result: after working with an analyst, you will clearly understand who you are making the application for, what user tasks it will solve, and how to make money from it.

UX design

Modern users are accustomed to thoughtful and high-quality interfaces. In conditions of high competition between brands, if something in the application seems inconvenient or incomprehensible to a person, he will simply follow another link in the search engine. Therefore, it is important to think through the user’s journey: what sequence of actions he will perform and how the site elements will respond to these actions. A UX designer creates a prototype – it identifies the main blocks and elements, and shows the interaction between them. 

Result: A finished application diagram, which shows the interface blocks and the relationships between them. Based on the prototype, you can evaluate the functionality of the application and its accessibility.

UI design

The interface designer’s job is to visualize the blocks that the UX designer came up with. UI design is the drawing of icons and buttons, layout of screens, selection of colors and fonts, and preparation of a UI style guide for further development. If you want to learn more about the work of a UI designer, read our articles about the design process and how we create style guides for our projects. 

Result: you will see an almost finished application, but not yet working. It is after the site design stage that the exact cost and development time can be confirmed. They will depend on the complexity of the project and the client’s wishes for function and design.


The front-end developer is responsible for the external part of the site that users see. But the frontend is not only about layout layouts. The front-end developer is responsible for adaptive and responsive design – that is, for the site to be displayed correctly on different devices and in browsers of different versions. 

Result: the design becomes interactive: you can press buttons and follow links. But the application does not yet perform its functions.


The next stage is the development of the internal part: how the application will work with databases, how payment, booking and other processes will occur. The backend developer is responsible for the correct operation of the site, communication between application components, data storage and structure, the logic of algorithms and calculations, and integration with external services – for example, with payment systems and social networks. 

Result: a fully working application.


This is a necessary step for the final application to work as intended. The main task of a tester is to check the operation of the application before release, so that the team enters the market with a high-quality product. Testers study product documentation and create test cases – a list of functions that need to be tested and their sequence. They then manually simulate user actions in different scenarios or write scripts for automated testing. After this, developers receive a report with a list of errors and recommendations for correction. 

Result: the application works without errors, the risk of their occurrence is minimised.

The application can then be launched for users. But the team does not stop working on it – it is entering the support stage . After release, developers ensure stable operation of the application and fix bugs found by users. And during support, the team can specifically collect feedback from users and improve the quality of the product – for example, adding new features or changing the design of ready-made sections of the application.

Development cost

The cost of developing a web application depends on its functionality. Let’s look at the most popular types of web applications. At the end we will provide a detailed assessment of the stages of work on each of them.

☝Of course, we provide only approximate figures: the final price of the application depends on many nuances. If you need more or, conversely, fewer functions, then the cost will change. 

A social network that implements:

  • chat;
  • news feed with comments;
  • public pages or forums;
  • user profile.

This application will cost us about 10,182,000 rubles.

Service aggregator for travellers: with booking hotels, train or air tickets. It should contain:

  • Personal Area;
  • search with filters;
  • blog with recommendations for tours;
  • payment
  • newsletter.

Such a web app development company will cost approximately 7,845,000 rubles.
