In this digital age, choosing the right tech stack for your project requires a great level of intelligence. For that, it is important to understand the difference between Mean and Mern – the two most popular full-stack technologies.

Within the JavaScript ecosystem, a specific app comprises a combination of technologies, called a “stack.” The MEAN and MERN stacks are the most popular technology stacks that are used by developers to build websites and mobile apps. 

But, what is the major difference between Mean and Mern? And, do developers prefer one over the other? 

The demand for mean stack development has been increasing at a high pace, which leads to more ease and convenience in web development projects. As we know, development is a tedious job including extensive codes to compile, debug, and execute, thus, developers find it a bit challenging to write code for every new project which is time-consuming. 

With a stack, it becomes easier to combine all libraries and frameworks in single or multiple stacks for quick coding.

It provides seamless code execution and reduces the risks of bugs that commonly arise in-app programming process.

It’s time to discover the basics of MEAN and MERN and understand the advantages of each technology stack used in the development process. Let’s together learn the difference and benefits of MEAN and MERN – two popular full-stack technologies to know which one to choose for your web development. 

Mean Stack v/s Mern Stack:

The demand of React v/s Angular manages the popularity of Mern vs Mean, respectively. Angular has been a very popular framework so far, however, React is overtaking it in recent years.

To ease the flow of coding and reduce possible errors, a number of development stacks have been designed for developers in real-time. The main three mechanisms of the development stack are front-end, back-end, and database. 

The front-end stack is for ‘customers’ and is based on frameworks like Html, CSS, JavaScript, AJAX, and JSON. Similarly, the back-end stack is for the ‘server’.

It runs on object-oriented based programming languages like Java, C, C++, .Net, PHP, Python, Perl, Swift, Ruby on Rails, etc. These languages receive a request and ensure response delivery with the help of hypertext transfer protocol. 

Database development is one of the significant elements in full-stack mean development with the main purpose of finding a raw form of data and defining it to bring out valuable information for customers. SQL, Oracle, Teradata, Informix, Sybase, Dbase, and Microsoft Access are popular databases worldwide. 

The Mean, Mern, Mevn, Flutter, and Serverless stack are the leading examples of full-stack development. This blog will help you understand the meaning of these stack technologies and find the significant difference between Mean and Mern. So, let’s get started with their definitions and objects used.      

Meaning of Mean Stack:

In laymen’s terms, the term stack refers to a pile of objects arranged neatly and systematically. It links all objects to each other. Web development requires two types of stacks – technology and development. 

They help to bring together all programming languages, frameworks, applications, library functions, etc to maintain robust coding practices for the web project. 

The Mean stack development has four major objects- Mongo Database, Express JS, Angular JS, and Node JS. Other than Mongo DB, which is a cross-platform No SQL database, the rest are strongly supported by JavaScript.

They use a single stack mean technology for both front-end and back-end frameworks. It is popularly known as full-stack development as it involves both client-side and server-side platforms. Mean is a free open-source JavaScript that is used in building actionable websites and applications for clients. 

Mean creates faster and customized applications that reflect dynamism and professionalism in your app development project. 

Meaning of Mern Stack:

The four major objects of the Mern stack app are MongoDB, Express, React, and Node. Everything is the same, just angular is replaced with React. With the help of this JavaScript framework, businesses get the opportunity to build fantastic single-page applications. 

React is significantly a comprehensive library that used coding on various devices and cross-browser platforms where it offers rich user interface design for web applications.

Mern combines all four objects and links them with JavaScript, XML, and virtual document object model (DOM) to build the front-end and back-end of the app more efficiently.

The best part of Mern technology is that it is a highly cost-effective open-source solution for companies to improve the communication between the client and server.

Most businesses hire the Mern stack developer for the development of vibrant and advanced web and mobile smartphone applications for their customers.

Mern Stack v/s Mean Stack:

Following are the primary differences between Mean and Mern stack development to understand which stack to use in 2021:



It consists of MongoDB, Express, Angular, and Node. 

  • Mongo is a NoSQL database that stores JavaScript object notation files and develops high-quality server-side applications. 
  • Express is a back-end application that runs at the server-side on the top of Node js. 
  • Angular is a client cornerstone structure that runs the front-end code and shows it in the browser.
  •  Last but not the least, Node is a server-side JavaScript web application that provides a running time endurance for coding. 



The Mern stack stands for MongoDB, Express, React, and Node. It is a famous javascript framework to use maximum trending technologies in a single stack. Mern has a database, front-end client, and backside server factors for the development of vibrant and actionable websites and mobile applications for customers.

Mean is a JavaScript framework, while Mern is a Javascript library that uses its features and code syntax for the development of web and mobile solutions. 

Mean stack v/s Mern stack also indicates that Mean uses a typescript offering exceptional productivity, and the latter uses JavaScript which offers relatively. Mean offers exceptional productivity and Mern offers slow productivity and efficiency levels for web developers. There is a bi-directional and unidirectional flow of data in the Mean and Mern stack.

The Mern has a smooth code rendering feature, whereas Mean only manages the code to operate in the browser.

Take Away:

Therefore, in a nutshell, the above are the described and the clear differences between the Mean and Mern Stack Development. Both frameworks are crucial for web and app development despite their differences. They gained popularity among developers in 2021 using futuristic technologies having a lasting value in the market.

These offer ultimate ease and satisfaction to the developers and prevent them from writing lengthy and time-consuming codes. It saves the extra effort of developers in executing the coding.

Companies like Accenture, Raindrop, Fiverr, UNIQLO, and Sisense use MEAN as their stack technology. Whereas brands like UberEats, Instagram, and Walmart use the MERN stack technology. Well, both these frameworks ensure an incredible user experience. Stability and scalability can be achieved with both the technologies

We can also conclude that enterprise-level projects prefer MEAN over MERN. This is because MERN keeps the UI simpler. Both are well-grounded for faster front-end development.

MEAN is preferred for large-scale applications while MERN is chosen for quicker development of smaller applications.
