The advent of Artificial Intelligence has radically transformed the world. We live in a digital realm wherein technology is scaling new unprecedented heights with each passing day. The mobile and web app market is mushrooming at full throttle, and with umpteen new apps venturing into the market every day, businesses stand at cross roads between MEAN stack vs MERN stack as robust app development is the only key to carve your distinct mark in today’s highly competitive mercenary world. 


It is thus imperative for you to make use of the best stack for furnishing fine app development, however having that said, you might be a little baffled and would be pondering what exactly MEAN and MERN Stack are.

So here’s a brief explanation of the two, and fret not as this would also be followed by an insightful overview of the major differences between MERN and MEAN stack.

What Is MEAN Stack?

MEAN per se stands for MongoDB, Express.js, Angular, and Node.js. It is a collection of JavaScript(JS) based technologies that developers use to develop excellent websites and mobile applications that are both progressive and responsive. MEAN Stack technology streamlines development and accelerates the entire development process. It is a sought-after, highly demanded technology that innumerable industries have made excellent use of. 

MEAN Stack is an open-source, user-friendly framework that functions on JavaScript technology and is also referred to as a full-stack. It offers a host of marvelous tools and plug-ins for efficient system administration. 

MEAN Stack assists developers make excellent websites, web apps. It enhances the API development process and helps resolve all other complex development challenges. 

YouTube, Flick, Tumblr, and Forbes are a few popular mobile apps built using MEAN Stack. 

The major elements of MEAN Stack are as follows – 

MongoDB: It is a document-based, detailed NoSQL database used for data storage in the form of JSON files.

Express.js: This is a back-end web app that functions efficiently on Node.js.

Angular: The front-end web framework operates the JavaScript code in a user’s browser.

Node.js: It is a JavaScript runtime environment to implement backend applications in JavaScript.

Also following are the benefits that MEAN Stack offers –

MEAN stack application development is quite a cakewalk as all types of apps can be created easily. 

Myriads of plug-ins and widgets are compatible with this stack, and the overall functionality of apps balloons tremendously because of the availability of such plug-ins and widgets. 

It enables real-time testing with built-in tools. 

Applications respond fast because a single language is used for both the back end and front end, and this thus increases the coordination. 

MEAN stack application development assiduously caters to the entire web development cycle, starting right from the frontend (client-side) development to the backend (server-side) development.

Supports Model View Controller (MVC) architecture for a spectacular development process.

Now that you know what MEAN Stack is, let’s talk about its competitor MERN Stack so that you can come to a conclusion when comparing MEAN vs MERN stack.

What Is MERN Stack?

MERN per se stands for MongoDB, Express.js, ReactJS, and Node.js. It is a renowned JavaScript stack developers use to furnish exceptionally brilliant MERN stack development services. MERN Stack is a wonderful amalgamation of the most avant-garde, cutting-edge technologies used to develop excellent web applications. 

MERN Stack hence enables a smooth and efficient development process. It creates a cluster of JavaScript frameworks, detailed databases, and runtime environments to provide developers with an end-to-end, lucid framework. 

Instagram, Facebook, WhatsApp, Netflix and Dropbox are some of the most eminent and widely used mobile apps that have been built using MERN Stack. 

The major elements of MERN Stack are as follows – 

MongoDB: This is an open-source document-based database.

React: It is a frontend JS library utilized to develop seamless user interfaces.

Express.js: This is a minimalist, albeit a high-speed web framework used for Node.js.

Node.js: This is designed on Chrome’s V8 JavaScript engine.

Mentioned below are the wonderful benefits that MEAN Stack offers –

  • Both the front end (client-side) and the back end (server-side) are covered using a single dynamic coding script. 
  • MEAN Stack minimizes all server costs. 
  • The entire labyrinth process can be easily completed with only JAVA and JSON. 
  • Streamlines development via the excellent Model View Controller (MVC) architecture that it perfectly supports to a tee. 
  • Enables real-time testing via robust built-in tools.
  • MEAN Stack operates on an open-source community, and the source code can be modified easily. 
  • Furnishes a one of its kind ease for reversing web apps to software or mobile apps. 

Now that you have a lucid understanding of what MEAN Stack and MERN Stack are, let’s roll up our sleeves as we are now going to dive into and comprehend the major difference between MERN and MEAN Stack.

Points of Difference Between MEAN Stack and MERN Stack

1. Angular JS vs React JS :

MEAN and MERN are full-stack frameworks with Java-coded components. However, one major difference that lies here is that MEAN utilizes Angular JavaScript, whereas MERN deploys the React JavaScript that Facebook has developed.  

And one would be amazed to know that as per the Hacker Rank Development Skill Report, 30% of the developers and programmers were keen to learn React JavaScript and 35.9% of developers even chose to develop using React JavaScript. Hence, this substantiates that MERN Stack enjoys greater popularity, albeit this should not be the sole deciding parameter as there are many more detailed intricacies mentioned below. So, before you ditch an Angular development company and choose React development, it is advisable to read the remaining blog.

2. Support and Assistance : 

Both MEAN and MERN Stack possess the common MongoDB, Express.js, and Node.js and hence Angular JavaScript and React JavaScript are the essential differentiators. While the Angular framework works brilliantly on typescript and templates with a steep learning curve, React JavaScript, on the other hand, does not possess much of a learning curve, but it furnishes excellent documentation.

3. Architecture

While MERN Stack undoubtedly furnishes a brilliant UI experience, developers still prefer the MEAN Stack for developing enterprise-level applications because, within their labyrinth architecture, the database and the UI code are divided with an intermediate layer that assists in managing and upscaling the code.

 4. Productiveness :

The MEAN Stack’s AngularJS offers excellent productivity. Angular JavaScript also boasts of CLI (Command Line Interface) that further augments the developer’s overall productivity and work ease by making it simpler for them to improve a code. React JS of the MERN Stack mandatorily requires third-party libraries to work in close accord with it, which in turn renders a relatively low productiveness to the developers. 

5. Data Flow :

Another important factor to consider when understanding the difference between full-stack and MERN stack is data flow. The Angular JavaScript of the MEAN Stack enables bidirectional data flow, and it automatically swaps the model state in case there are any changes in the UI. This bi-directional data-binding furnished by AngularJS proves to be a lot more viable for all small-scale projects. That’s why businesses with small projects often prefer an AngularJS development company.

However, on the contrary, React JavaScript offers unidirectional data flow. This, therefore, means that developers can make changes in the UI only post changing the initial model state.

React thus furnishes a better data overview that helps carry out large-scale projects. 

6. Mobile App Development: 

Angular JS furnishes an exceptionally stupendous framework that enables developers to create stellar hybrid mobile applications that are extremely cost-effective. However, hybrid mobile applications designed for iOS and Android platforms using AngularJS may at times tarnish the native user experience. On the contrary, React yields maximum native user experience. Thus the MERN Stack is unquestionably a lot more reliable than the MEAN Stack when it comes to great mobile app development.

7. Third-Party Libraries :

Developers make use of multiple third-party libraries to carry out large-scale application development successfully. Angular JS renders various ready-to-use features that facilitate developers to utilize the third-party libraries. The Angular JavaScript framework also supports HTTP calls while connecting with the backend server. However, React JS requires additional libraries for successfully keeping up with similar requests.

8. Cost-Effectiveness :

AngularJS is an all-inclusive framework that assists businesses in rapidly magnifying their overall profits and revenue as the Angular Command Line Interface facilitates designers to redesign apps without incurring any additional costs. However, upgrading your existing code from outsider libraries would cost you considerably in the case of React JS. 

9. Scalable and Secure :

While both MEAN and MERN Stacks furnish robust security, MERN Stack would, however, be your best bet as it is unquestionably a lot more scalable and secure.

Voila! You can finally take a sigh of relief as this is all. We are sure you would have understood both these stacks to a tee, with all their distinct advantages and drawbacks. 

Both the MEAN and MERN are robust technology stacks that render an excellent user experience with a plethora of incredibly wonderful features that these two possess, but you must assiduously consider the nature of your business before choosing one of these stacks. 

The enterprise-level business projects require MEAN Stack over MERN Stack. 

MEAN is the go-to stack for large-scale applications, whereas MERN, on the contrary, is great for the faster development of small apps.
