Are you unfamiliar with programming languages? In that case, the concept of the tech stack can be challenging for you to understand. But, to know what you need to build a business website or an application, it’s essential to understand what is a tech stack first. Once you get that, you must then put your mind to selecting the right tech stack for your project. This blog will walk you through everything there is to learn about a tech stack. So, keep reading!

What is a Tech Stack?

A builder needs a lot of materials to build a house. Similarly, a tech stack meaning is a combination of all the technologies (materials). A company uses them to develop and run an application. It is often referred to as a solutions stack. Hence, a technology stack usually consists of the following:

  • programming languages
  • frameworks
  • a database
  • front-end technologies and tools
  • back-end development tools
  • applications connected via APIs

In the case of product companies, it usually consists of tools that help measure the product and user analytics. 

What is the Structure of a Tech Stack?

An application has a double software mechanism. 1 is the client’s side, and the other is the server side. You would know them as the front-end stack and the back-end. Note that each layer of an application is built using various functionalities and creating a technical stack. The middleware acts like a transition layer. It links the front-end development and the back-end languages and components. Moving ahead, we discuss all these components to give you a better understanding of them.

Technology Stack in Front-End Development

Be clear about one thing; the users interact with the client side of the product. This is the visual side of your product. Examples of front-end stack:

  • JavaScript – makes web pages more interactive. It lets you construct dynamic elements on web pages. 
  • HTML – used to create and display electronic documents.
  • CSS – it is in charge of page layout and format. (Sizes, font styles, design, color, and other web development elements.)

Technology Stack in Back-End Development

This is the invisible part of the product. This includes the technologies that operate in the background. Thus, this part stores and handles data. Moreover, it also processes and responds to incoming requests. Furthermore, it allows the front end to achieve its goal. Hence, the back-end stack includes the following technologies:

  • Programming languages
  • Databases
  • Frameworks and Libraries
  • Web Servers
  • Cloud Infrastructures

Technology Stack in Mobile App Development

There are a few programming languages and frameworks only suitable for building applications. Be it Android or iOS. Furthermore, here is a list of technologies used for Android and iOS:

  • UI frameworks – Android UI, Jetpack Compose, UI kit

For iOS:

  • Programming languages – Swift and Objective-C
  • Development Tools – Xcode, AppCode
  • UI Frameworks – SwiftUI

Furthermore, let’s talk about hybrid mobile app development. They are developed for several platforms simultaneously. Hence, these applications are built using a combination of web development and native technologies. Moreover, app development for various platforms provides your business with many advantages, such as:

  • Help you reach a broader target audience
  • Save time, money, and energy on the development
  • Increasing time-to-market 

Also, some common frameworks for hybrid mobile apps are: 

  • React Native

Factors for Choosing a Tech Stack

Here is a list of factors you must consider before choosing a tech stack for your business or project.

1. Market and Industry Research

Before you move to the product’s development phase, market research is a must. Thus, you must not forget to check out the project requirements. If you don’t do research, you might end up investing your time, money, and energy into an impractical project.

2. Technology Knowledge

In case you already have sufficient knowledge and are an industry professional, this gives you some command over selecting a precise tech stack for your project. However, this won’t work for non-tech-savvy people. If you choose the wrong stack, it will only lead to many changes in the long run. Hence, it is best to consult with an expert in the field, for example, a tech agency. 

3. Project Type, Needs, and Features

This depends on the scale of a project. Is it a small, medium, or large-scale project? Also, inspect the project’s size, features, functionalities, and business objectives. Furthermore, based on this research, you can make an informed decision. Note that the bigger the project size, the more advanced the tech stack will be. 

4. The Technology Platform

Here, you must identify what your audience likes or dislikes. Figure out whether they will like and utilize your product or not. If yes, how will they approach it? What is the most used device among your target audience? Is it a PC or a smartphone? 

5. Team Experience and Expertise

Your team must have in-depth knowledge and expertise. Moreover, they must be well-versed in technical and architectural know-how. Furthermore, this helps them compare the perks, limitations, and significant differences between various technology stacks. Consequently, it is best to prioritize full-stack technology.

What Determines the Cost of the Tech Stack?

Having covered the fundamentals of choosing a technology stack, you must focus on the budget. Often, startups are on a limited budget. Hence, this part will walk you through the factors that influence the price of a tech stack. 


The price of a tech stack is highly influenced by the maturity and popularity of its technologies. Thus, the old and popular technologies are more reliable. Also, they have a large pool of specialists to choose from. It is easy to find developers who specialize in Java. However, finding Clojure developers is difficult. Thus, the specialists who know the new or “unpopular” technology are more expensive.

In that case, turning to the old school is a better option. However, we emphasize that technologies should be both popular and mature.


Licensed solutions will often cost you more. Since they are subscriptions, they include a fee for traffic, usage in general, and CPU charges. 

Maintenance Cost

Most companies that employ software systems spend a considerable amount of money on their maintenance. Therefore, mind such expenditures when choosing a tech stack and hiring expert developers. Furthermore, you must consider opting for cheaper open-source technologies. They can be updated and changed without limitations.
