MEAN Stack vs. MERN Stack: comparison between the two Tech Stacks

Mobile and web application development services have advanced to the next level in recent years; these applications are built using the Stack of several technologies. A stack is a set of programming languages, technologies, and frameworks. In this Blog, we are comparing MEAN and MERN Stack like differences and similarities of these two.

So, let’s start with an overview of the MEAN and MERN stacks.

What is MEAN Stack?

MEAN Stack is a free and open-source JavaScript software stack that enables you to Develop cutting-edge online and web applications. MEAN Stack Include MongoDB, Express, Angular, and Node.js. It’s an end-to-end web development framework that makes it easy for software engineers to Develop web and mobile applications.

Benefits of MEAN Stack

MEAN makes it easy to switch between the client and the server: It is easy, simple, and fast to use when you are looking to develop a website. This is because both the client-side and server-side coding may be done in JavaScript. Using Node.js can allow developers to deploy various applications directly on a server without any need of having them deployed on some stand-alone server.

It is extremely flexible: Once you have developed an application successfully, you can quickly test its functionality on a cloud platform With MEAN Stack. MEAN Stack enables developers to develop, introduce, and test applications in the cloud. When you need to add some extra information, you can easily add a field. MongoDB is well-suited to the cloud, with features including automated replication and cluster support.

MEAN allows isomorphic coding: You can easily transfer code from one framework to another when you use the MEAN Stack. This makes MEAN Stack a user-friendly web development tool. Since MEAN allows isomorphic coding, developers can achieve optimal results in a short period of time by working with it.

MEAN makes use of JSON: MEAN uses JSON or JavaScript Object Notation and is closely related to NodeJS and AngularJS. MongoDB is another component-oriented relational database that allows users to save documents in JSON format.

It is open-source and offers cloud support: MEAN stack is open source, which means they are available for free. This means that when working on a project, web developers can use public repositories and libraries. This will undoubtedly reduce development costs.

What is MERN Stack?

MERN stack is a web development framework. MongoDB, ExpressJS, ReactJS, and NodeJS are the MERN Stack components. It’s an end-to-end web development framework that makes it easy for software engineers to Develop web and mobile applications. MEAN and MERN stacks are quite similar, with three common components.

Benefits of MERN Stack

  • Covers complete web development cycle from frontend to backend with JS
  • Supports MVC architecture
  • As it is a JavaScript stack, developers can only be pro in JSON and JavaScript
  • Combination of the best technologies -MongoDB, React, Node.js and Express.js
  • As an extensive built-in suite to test tools
  • It is an open-source framework

MEAN Stack vs. MERN Stack: A detailed comparison

Parameters MEAN MERN
Architecture Component-Based Component-Based
Scalability Medium High
Type JavaScript Framework JavaScript Library
Language Typescript JavaScript, JSX
DOM Regular DOM Virtual DOM
Data Binding One-Way & Two-Way Only One-Way
Learning Curve Medium Low

MEAN or MERN: Which is more popular

MEAN and MERN Stack both are popular. The demand for MEAN and MERN stacks is proportional to the demand for AngularJs and ReactsJs. Although Angular is well-known, React is currently overtaking Angular.


It’s impossible to say which stack will win this MERN vs. MEAN battle because both MERN and MEAN have top-level features and functions. However, if you want to create a dynamic web app, you can use MERN or MEAN, depending on your needs…
