MEAN Stack Vs MERN Stack: A comprehensive Comparison

MEAN Stack is the most used open-source JavaScript framework in 2018. It allows developers working for top mobile app development companies to build modern web applications with MongoDB, Express, AngularJS, and Node.js. MEAN Stack has become popular for its speed, reliability, and scalability. The second most used open-source software stack is the MERN stack which is also known as Micro-Era Enterprise Node (MERN) stack. It consists of MongoDB, Express, React, Redux, or Angular 2+.

Benefits of MEAN Stack

Here are some of the benefits –

  • Encapsulates the entire web development cycle, from frontend to backend, i.e., client-side and server-side, with JavaScript Model View Controller (MVC) architecture support for a seamless development process.
  • To keep web app development structured that resists repetitive menial labor.
  • Extract the best out of MongoDB, Angular JS, Node.JS, and Express.JS
  • A pre-installed comprehensive tool testing suite is pre-installed.
  • An open-source framework with strong community support
  • The server layer is simplified using JavaScript.
  • MEAN ensures that the code is isomorphic.

However, to avail of such amazing benefits and harness the true potential of the Mean stack, you ought to call on the services of app development companies or hire dedicated app developers to take your business to the next level.

Benefits of MERN Stack

MERN is a software stack that has been developed to provide the benefits of both front-end and back-end development.

Some of the benefits of the MERN stack are:

• It makes it easier for developers to build and deploy apps.

• It helps teams work more efficiently as they can be separated into different areas.

• It also increases security because it separates your app’s source code from other areas such as databases, servers, and networks.


MERN Stack is a mobile app development stack that consists of MongoDB, ExpressJS, React Native and Node.js.

1) Data Flow: MEAN uses the HTTP protocol to transmit data from the server to the client while MERN uses its own data storage system called MongoDB. This means that when you must retrieve information from your database in MEAN it will be done using RESTful requests while in MERN you can access your database using standard SQL commands.

2) Third-Party Support: In terms of third-party support MEAN has a lot more support because there are many frameworks built on top of it like Angular or Vue which means there are a lot more people developing apps on top of this framework than MERN does with only one framework in mind (React Native).

3) Managing and Upgrading the Code: Both stacks have their own set of benefits but when it comes down to managing code changes, MEAN has a big advantage over MERN because they use Typescript which makes them easier to manage when compared with JavaScript.

4) Testing: The test coverage provided by both frameworks is similar but not quite equal because in MEAN they use Mocha which provides better testing capabilities than Jest whereas in MERN they use Enzyme which provides better testing capabilities than Mocha does.

Scalability and Security of MEAN & MERN STACK

The MERN stack is more secure and scalable than the MEAN stack.

Mean stack is known to be the most popular web development framework in use today with Node.js.

MERN stands for Mongo, Express, React, and Node.js while MEAN stands for MongoDB, Express, AngularJS, and Node.

Choosing The Right Tech

The two stacks are quite similar. They can be used in both client-side and server-side programming. Both stacks use JavaScript as their main programming language. The difference between these two stacks is in how they organize code into modules and in what they provide for managing state.

The advantage of the MERN stack is that it allows for the development of hybrid and web with smaller amounts of code because it uses components from other tools such as Redux or Flow. Another advantage is that it has a single-page application architecture which means you can build your app without having to worry about pages load times as much as possible.

MERN stacks are considered to be more efficient than MEAN stacks because they have fewer moving parts. They are also known to be faster and easier to build with.

It has more flexibility than MERN in terms of databases because it can use different ones like PostgreSQL or SQLite3 which do not require any additional software installation on the server-side, unlike MongoDB where they need to be installed separately by using npm install Mongo DB.

However, there are many differences between the two –

1. MEAN stack has MongoDB as its database whereas MERN stack uses MySQL instead of MongoDB.

2. MEAN stack has NodeJS as its front-end framework whereas MERN stack uses AngularJS as its front-end framework.

3. MEAN stack provides an API that allows developers to build hybrid applications and not native apps on top of it whereas the MERN stack doesn’t provide any APIs for developers to build applications on top of it directly or indirectly through React or Vuejs or any other frameworks.

Summing Up

In terms of simplicity and functionality, the MEAN stack offers a more straightforward approach to building a website or app without too many moving parts that can lead to problems down the line. However, it does not offer as much flexibility as the MERN stack because it lacks support for webpack which allows developers to bundle their application code with additional libraries for optimization purposes such as using Sass instead of CSS.
