MEAN vs. MERN: Which Development Stack Should You Choose?

Previously, web applications were limited to specific areas, but businesses are increasingly using them with increased internet usage. The right tech stack is required to develop a successful and cost-effective web app.

MEAN vs. MERN: Which Development Stack Should You Choose?

Over the last decade, application stack development has reached a new level. Every web platform we see on the Internet has two sides: the frontend, a visualization of data that the user sees, and the backend, which includes web development and its interface.

The backend works in the background to manage the data that the user sees on the front end. The database and server-side programming make up the backend. On the other hand, the technology stack consists of a collection of tools.

MEAN and MERN are two such tech stacks that most companies prefer. It often becomes the point of discussion that which is better MEAN vs MERN. The choice of tech stack depends upon your project requirements therefore, you can seek assistance from MEAN or MERN stack development company to get the best web solution for your business. This blog will cover the point of difference between these two stacks.

Let's know about both the tech stacks individually along with their advantages. 

Difference Between MEAN and MERN

MEAN Stack

MERN stack is the acronym for JavaScript libraries such as MongoDB, ExpressJS, AngularJS, and NodeJS. It is a modern approach to web development with an extensive suite of built-in testing tools. 

Benefits of using MEAN stack for web development.

  1. It is highly flexible toward code transfer within other frameworks. 
  2. With the help of the MERN stack development services, businesses can develop a robust framework that supports their daily business needs.
  3. This tech stack is helpful for enterprises requiring Single Page Application (SPA) with dynamic UI. 
  4. It supports MVC (Model View Controller) architecture, making web app building smooth and easy.
  5. It helps keep web app development organized by resisting unnecessary grunt work.
  6. With the changing needs, this tech stack is constantly updating to improve code efficiency and reduce code size.
  7. Every piece of code, including the web app server, runs on a chrome-based JavaScript engine that minimizes overall memory requirements and improves response time. 


MERN is another open-source technology stack; you can also categorize this as a full stack. The abbreviation MERN is used for MongoDB, ExpressJS, ReactJS, and NodeJS. With the help of this MERN stack, you can develop web and hybrid mobile apps with it.

MERN is a collection of JavaScript-based databases, frameworks, and runtime environments like MEAN. The MERN stack offers an end-to-end framework for developers, and its popularity is increasing.

Benefits of using MERN stack for your project development.

  1. It covers the complete development cycle, whether frontend coding or backend development.
  2. This stack takes care of MVC (Model-View-Controller) architecture for a smooth and uniform web app creation.
  3. Developers must have knowledge and expertise in JSON and JavaScript technologies to use the MERN stack.
  4. It utilizes Virtual DOM.
  5. This stack comes with a pre-built suite of testing tools.
  6. It is an open-source tech stack with vast community support.
  7. With the selection of experienced MERN stack development services, you can create high-performing and robust web apps with exclusive features for your business. 

Difference between MEAN and MERN Stack for your Business

1. Learning Curve

Thanks to their extensive documentation and host learning materials, you can quickly learn about Node.js, Express.js, and MongoDB. Regarding the learning curve, there is no discernible difference between the MEAN and MERN stacks.

It is entirely dependent on two technologies: AngularJS and ReactJS. AngularJS is a JavaScript framework that makes use of templates and Typescript. The Angular learning curve may be steeper, but ReactJS is not as difficult.

2. Scalability and Security

Both of these frameworks are reliable as they offer high scalability and security. Hence, if you want to develop a secure web app, these tech stacks suit that purpose. But if you want a scalable web app that can align with your growing business requirement, then MERN is the best choice. Hence, by partnering with an experienced MERN stack development company, you can build a scalable and secure website for your organization. 

3. Architecture

The MERN stack provides fast UI rendering. Similarly, AngularJS provides a well-structured framework that can be used to support an MVW or MVC architecture. Furthermore, in these architectures, the UI code and the database are separated by a middle layer that aids in code updating and management. It is also one of the reasons why the MEAN stack is preferred for developing enterprise-level applications.

4. Flow of Data

AngularJS supports bidirectional data flow. As a result, the model state changes automatically when the UI changes. For small-scale projects, AngularJS's bidirectional data-binding capability is far more practical. Furthermore, ReactJS supports unidirectional data flow, which means that developers can only change the UI after updating the model state.

As a result, it provides a better data overview, allowing us to handle large-scale projects. As a result, the MEAN stack can be used for small-scale projects, while the MERN stack can be used for large-scale projects.

5. Productivity

AngularJS in the MEAN stack provides greater productivity as a complete framework. It includes a Command Line Interface (CLI) that boosts a developer's productivity by giving helpful functionality and tools. It makes it simple to upgrade code and download new modules. Third-party libraries with low productivity are required to support ReactJS in the MERN stack. Additionally, upgrading the code becomes more difficult.

Wrapping It Up!!

As the web development industry expands, there is a greater need for full tech stacks such as MEAN and MERN. It is difficult to predict which MEAN vs. MERN will win the battle because each has its advantages and disadvantages. A dynamic web application should be built with MEAN or MERN according to your business requirements and the efficiency of the technologies.

You can also look for the best web development company to assist you in determining the best tech stack based on your needs and requirements. Choosing the right tech stack is critical when developing a robust web app.
