The digital world is transforming every moment and we are experiencing a lot of tech advancements and new market demands daily. Hence, in this digital era, having an app or website is not the single way of growing your business. You must be smart enough in selecting the right tech stack for your project.

Choosing the right technology stack for your business will impact your future development also. So, should you employ either MEAN stack or MERN stack? Which one will work greater for your business? In terms of getting answers to these questions, you must learn the basics like differences, similarities, and perks of these two.

So, let’s begin with introducing both the MEAN stack and MERN stack first!

What is MEAN Stack?

This is full-stack and extremely popular technology stack. The term MEAN stands for MongoDB, Express.js, Angular, and Node.js respectively. For developing mobile and web apps, programmers use this stack.

MEAN Stack

MEAN is an open-source, JavaScript-based technology stack. Since this stack provides essential plugins and tools, it is helpful for developers for building mobile and web apps fast.

Benefits of Selecting MEAN Stack

  • It is less costly. Every technology in the MEAN stack is open-source that lowers the development cost.
  • MEAN stack makes Isomorphic coding possible. With its help, you can easily move the code to another framework that is written in a particular framework.
  • Angular is a JavaScript-based open-source framework that provides reusability, maintenance, testability, and high speed.
  • It is cloud-compatible and open-source. MongoDB helps in sending cloud functions within the app by reducing the circle space cost.
  • Easy switching between server-side and client-side is possible with MEAN stack. This is beneficial for developers for easy and quick development with JavaScript. Developers must know JavaScript to handle the whole project with it.

What is MERN Stack?

This is another open-source tech stack that can also be categorized as full-stack. The term MERN stands for MongoDB, Express.js, ReactJS, and Node.js. This helps build hybrid mobile apps and web apps with it.

MERN Stack

The MERN stack is created to provide a smoother development process. It is a group of JavaScript-based frameworks, databases, and runtime environments. This tech stack provides an end-to-end framework to developers, and it is becoming popular faster.

Benefits of Selecting MERN Stack

  • Set up with amazing community support.
  • In-built wide suite of testing tools.
  • React library gives you access to high-end tools for building apps. Developers are free to use the library for designing their web apps.
  • It supports model view controller (MVC) architecture for a smooth development process.
  • Developers must be experts in JavaScript and JSON to employ this JavaScript stack.
  • This tech stack covers both the development cycles from front-end to back-end with JavaScript.
  • Developers can use codes written on React on both browsers and servers. This JS stack gives the flexibility of making pages on the server when required.

MEAN or MERN: Which One Is High on Demand?

You need to select a popular tech stack and your scopes of finding expert developers increase if you select the right stack as more developers would possibly know it.

The popularity of Angular vs. React inspires MEAN vs. MERN stacks’ popularity, respectively. Although Angular has been very famous, now React is beating it presently.

According to the 2020 HackerRank Developer Skills Report, 32.3% of developers wanted to learn the React in 2020, which made it very famous. A similar number for Angular decreased to 27.6%, which signifies that React is becoming more famous than Angular.

The 2019 StackOverflow Developer Survey report also supports the same observation that the React is becoming popular. According to this report, almost 74.5% of developers like to develop using React. The same number for Angular is 57.6%.

Both React and Angular are extremely on demand. Nevertheless, with time, you will find it simpler to employ React developers than Angular developers.

MEAN Stack vs. MERN Stack: A Detailed Comparison

MEAN vs MERN comparison

The main difference between MEAN stack and MERN stack is the use of Angular and React, respectively. Both the stacks have some positive and negative characteristics.

Aside from the advantages provided by both the stacks, some factors make the variation between them. Let’s move directly to the point to conclude!

1. Learning Curve

Node.js, MongoDB, and Express.js are very popular and they contain great documentation. There is no apparent difference in the learning curve of MEAN and MERN. Nevertheless, your learning curve will change between React and Angular.

The Angular framework utilizes templates and Typescript. You may discover a steeper learning curve with Angular, while the React does not contain much learning curve.

2. Profitability

Since Node.js, Express.js, and MongoDB are common to both MERN and MEAN stacks, the profitability comparison between these two would reveal between React and Angular.

Angular, being a complete framework, provides better profitability. Generally, you would use third-party libraries associated with React that provide lower designer productivity.

Angular features a CLI (Command Line Interface) and this enhances the productivity of designers. And when you redesign your code, you will discover that the Angular CLI makes it easier. Due to the existence of outsider libraries, updating your React code is a more added exertion.

3. Data Flow

In the case of Angular, the data flow is bidirectional, i.e. if you alter the UI, then it transforms the model state automatically. In the case of React, the data flow is unidirectional. So, if you use React, you can alter the UI only after transforming the model state.

React’s unidirectional data binding gives a better data overview, which helps handle large projects. And this makes the MERN stack more favorable for handling large projects.

In case you are working on a small project, the bidirectional data binding provided by Angular becomes a more efficient method. Here, MEAN stack helps!

4. Third-Party Support

While working on building enterprise-level apps, using third-party libraries is another great factor for contemplating. MEAN contains Angular that has in-built features for supporting HTTP calls and uniting to the backend.

Nevertheless, ReactJS has alternative libraries for bringing in similar functionality. MEAN handles third-party extensions in a plug-and-play way, while MERN needs additional configurations for performing a similar thing.

5. Managing and Upgrading the Code

With the benefit of using Angular, the MEAN stack makes handling and upgrading your code simpler. Being a well-organized and complete framework, Angular can better assist the MVC architecture.

You can simply separate the database-related code from UI-related code using an intermediate layer that makes managing and upgrading your code easier. Managing and upgrading the React code is more involved exertion due to the presence of third party libraries.

6. Mobile App Development

For mobile app development, Angular provides the Ionic framework that helps you build hybrid mobile applications. These applications keep the development expense low since you have only one codebase for both iOS and Android platforms. Nevertheless, hybrid applications let down the native user experience.

In this matter, React Native is a bit different. It provides an almost-native user experience; hence, you can find that the MERN stack is a better option for mobile app development.

7. Testing

The experience of angular app testers is different from the experience of React app testers. Generally, this will impact your preference between the MEAN stack and MERN stack. Using only one tool like Jasmine, you can test an Angular app easily.

However, this is different in the case of a React app, where you will require employing many tools. You will require using a tool like Jest to test the JS code, while you might require using a tool like Enzyme to test the elements. You will possibly employ many third-party libraries when coding your app using React; hence, your effort for testing is amazing.

8. Scalability and Security

Both MERN stack and MEAN stack provide the best-in-class security. Hence, you can choose any one of them.

However, in terms of security, MERN wins the game as it is more scalable than MEAN.

9. Large-Scale Apps

In case you are working on an eCommerce type project, the MEAN stack is a perfect option. It can work as the pillar of dynamic web apps and introduce a streamlined approach for building prototypes. I recommend MEAN stack for developing large-scale apps on full-stack development frameworks.

10. UI Requirements

Want a simple yet sophisticated UI rendering for your app? Then, go for the MERN stack for accomplishing that. It can create a frame and showcase it on the screen immediately, making sure a seamless user experience.

11. Expertise and Experience of the Development Team

In case your development team is highly expert and experienced in web frameworks, supporting documentation is not very crucial. In this regard, the learning curve is less appropriate, which enables you to select the MEAN stack.

If your development team possesses a moderate experience level, you must pay heed to the learning curve, so the MERN stack is a greater option in this matter.

12. MVC Support

In case you will be developing an enterprise-level app, you must keep up with a complete architecture. This is why you must choose the MEAN stack and not the MERN stack.

Selecting this will help you receive the assistance of the Model-View-Controller architecture. However, you can go with the MEAN stack if you will manage the code simply.

13. CRUD Apps

MERN stack allows you to create and develop a CRUD (Create, Read, Update, and Delete) app easily from beginning to end.

The React usage manages the data change fast and provides a great UI. For building a mobile app or a single-page app, MERN is a perfect framework.

14. Prevention of Defects

If selecting a stack with the possibility of basic code error prevention is important to you, the MEAN stack is the best option for you. Angular utilizes Typescripts, a framework that avoids basic coding errors at the phase of coding.

15. The Long-Term Improvement and Maintenance

Both React and Angular are significantly popular. But React is becoming more popular and it will become simpler to hire React developers in the future.

If you have a large pipeline of improvement tasks for your app and predict significant long-term maintenance needs, consider utilizing the MERN stack.

16. Performance

The MEAN stack utilizes Angular that updates the real DOM (Document Object Model). DOM acts as the programming interface for XML and HTML documents.

On the other hand, MERN utilizes React that updates the virtual DOM. So, you can code applications more rapidly by using MERN.

Thereby, no framework can answer every business objective. You need to conduct a study on every feature, match them with the fast development needs, and select wisely to get a better result and accomplish your business goals.


The close competition between the MEAN stack and MERN stack makes it very tough to choose one or justify both of them. After all, both technologies have best-in-class functionality and features. So, according to your business requirements, select MEAN or MERN stack to develop a dynamic app.
