Congratulations on deciding to bring your fantastic startup business idea to life! Now, how do you ensure its success?

While several factors will help your startup succeed in this digital age, having the right technological foundation cannot be overstated. But how great the tech foundation will be is heavily determined by whether you use the best tech stack for your startup.

A startup’s choice of technology stack is a strategic move that determines the business’s trajectory–from development to accessibility, scalability, and long-term growth.

In this article, we’ll delve further into the topic of the best tech stack for startups. We’ll cover the layers of a tech stack and the right combination for startups. Let’s get started!

Overview of the best tech stack for startups

A tech stack is a combination of technologies used in the development and functioning of a software product.

A typical tech stack consists of several key components, each serving a specific purpose in the development process. Some of the core ones you’ll have to consider for your startup include:

The key layers of a tech stack
  • Operating system: This is the foundational component of a tech stack since it provides the basic functionalities for other software components. The key operating systems include Windows, MacOS, Linux, Android, and iOS.
  • Database: A database stores and manages the data for the application. Examples include MySQL, PostgreSQL, MongoDB, and SQLite.
  • Programming Language: The programming language is used to write the application’s code. Popular languages include JavaScript, Python, Ruby, and Dart–one of the top languages for mobile app development.
  • Back-end framework: The back-end layer supports business logic and functionality that is not visible to the users. Back-end frameworks include Django (Python), Ruby on Rails, and Express.js.
  • Front-end framework: This layer helps build interactive user interfaces and ensures awesome user experiences. Popular frameworks include React Native, Angular, Vue.js, and Flutter.
  • Server: This refers to the physical or virtual server where the application is hosted. It can be on-premises and in the cloud, using platforms like Amazon Web Services (AWS) or MS Azure.

Now that you understand the layers let’s go ahead and look at the importance of choosing the best tech stack for startups.

Why do you need the best tech stack for startup?

The significance of choosing the right tech stack cannot be overstated. The best tech stack for startup businesses enhances productivity, facilitates faster development cycles, and ensures a smoother user experience – all of which provide a competitive advantage.

Besides that, going for the best tech stack will lead to a more reliable and secure product. This then leads to a happy and loyal user base that will eventually translate into business growth.

Also, startups operate in dynamic environments where requirements keep on changing. By choosing the best tech stack for your startup, it’s easy to integrate emerging technologies and shifting trends. This ensures your startup remains relevant in a constantly evolving market.

Factors to consider when choosing a tech stack for startups

There is a myriad of technologies out there, which can be overwhelming. Consider the following factors to ensure you’re making an informed decision. 

Project size

The size and complexity of the project play a crucial role in tech stack selection.

For instance, if you are working on a small project like a simple app with basic features, you’ll require an equally simple stack. The stack can combine a CMS like WordPress and a common programming language like JavaScript or C++.

A larger application project, however, will require a more complex tech stack to achieve the desired level of functionality.


Scalability is the other core factor when choosing the best tech stack for startups. You may start small, but the goal of every startup is to grow. 

As such, ensure your tech stack choice can comfortably accommodate your current and future startup product strategy. The technologies you choose should have scalable features to continue serving you through any future trends and transformations.


While you want the best, you can’t choose a tech stack that is out of your price range. Therefore, consider both initial and long-term costs, including licensing fees, hosting expenses, development resources, and maintenance costs.

But that’s not all. You should also consider how much it will cost you to get the right team.

Think about this. Most developers understand common technologies like HTML, C++, Python, and JavaScript. This means choosing these technologies will cost less compared to complex and unique technologies.


You want to launch your product on time and enjoy the first-mover advantage. This is why you should always consider the tech stack’s development speed.

A tech stack with frameworks like Node.js and React and tools that facilitate quick prototyping and development cycles can be an advantage.

Also, always choose a tech stack that your team understands and one that empowers them to achieve more. Doing this will help you speed up the development process, allowing you to launch a bug-free app on time.

Active community

The size and engagement levels of the developer community around a tech stack are crucial factors. A great community will help you access resources and information that make problem-solving more efficient.

Breakdown of popular tech stacks

Here is a breakdown of the most popular and some of the best tech stacks for startups:

1. MEAN stack

MEAN is an open-source JavaScript-based stack. This means that all layers of the MEAN stack use Javascript, which leads to rapid development.

MEAN stack

The technologies used in the MEAN stack include MongoDB for database, Express.js for back-end development, AngularJS for front-end development, and Node.js for server-side applications.

Advantages of MEAN

  • The MEAN stack uses open-source technology. That means developers can enjoy free access, making it a cost-effective tech stack option for startups.
  • Great for real-time applications thanks to a web app presentation layer that allows for demonstrations and live updates.
  • It is compatible with all the major operating systems.
  • The MEAN apps can be written in one programming language (both the server and client side). This encourages efficient workflow management between clients and servers.

Disadvantages of MEAN

  • AngularJS has a steep learning curve.
  • MEAN stack requires frequent updates to each component, which means high maintenance costs.
  • Not great for large-scale apps with heavy workflows due to the higher risk of losing data.
  • It is also not ideal for a compute-heavy backend.

2. MERN stack

The MERN stack is a MEAN variation, where React replaces Angular JS.

MERN stack

React has a powerful library that allows developers to write code that can be used on servers and browsers simultaneously.

Advantages of MERN

  • Being a close variation of the MEAN stack, the two share advantages. However, React offers higher flexibility and an easier learning curve.

Disadvantages of MERN

  • React’s dynamic typing might lead to runtime errors that could impact efficiency.

3. Ruby on Rails (RoR)

Ruby on Rails is popular because it follows the Convention over Configuration (CoC) principle, which reduces tedious configuration tasks to simplify development. RoR also uses the Model-View-Controller (MVC) design pattern.
