In the current world, web applications that are built using a combination of programming languages, frameworks, and libraries have become an essential tool for businesses to reach a wider audience and provide their services online. The use of web applications has increased over the years, and with it, the need for powerful web development tools has also grown. Two popular tech stacks for building web applications are MEAN and MERN. 

MEAN stack and MERN stack are often compared or confused with each other because they have similar names and share some of the same technologies. However, there are significant differences between the two, and which one is better depends on the specific requirements of the project. 

Defining MEAN and MERN stack 

The MEAN stack stands for MongoDB, Express, Angular, and Node.js, while the MERN stack comprises MongoDB, Express, React, and Node.js. The primary difference between the two is the use of Angular in the MEAN stack and React in the MERN stack. 

The MEAN stack has been around for longer than the MERN stack, and it is a popular choice for building web applications. The MEAN stack uses Angular, a popular front-end framework for building dynamic web applications. Angular provides a complete solution for building client-side applications, and it is ideal for building complex and data-intensive applications. Hire MEAN stack developers to build a robust, flexible, and scalable app. 

On the other hand, the MERN stack is a relatively new stack that has gained popularity in recent years. The MERN stack uses React, another popular front-end framework for building user interfaces. React is known for its simplicity, performance, and ease of use. Hire MERN stack developers to build lightweight and fast web applications. 

Difference between MEAN and MERN stack 

Both the MEAN and MERN stacks have their unique features and benefits. The MEAN stack is ideal for building large and complex applications that require a robust and scalable framework. It is also a good choice for building applications that require real-time data processing and analysis. The MERN stack, on the other hand, is ideal for building fast and lightweight applications that require a simple and intuitive user interface. 

To help you understand the differences between the two stacks, here is a table that summarizes their features: 


MEAN Stack 

MERN Stack 










Server Framework 




MVC (Model-View-Controller) 

MERN (Model-View-Controller-React) 


Robust, Scalable, Real-time data analysis 

Fast, Lightweight, Simple UI 

Popular Projects 

PayPal, Netflix, LinkedIn 

Uber, Airbnb, WhatsApp, Dropbox, and Shopify 


In conclusion, both the MEAN and MERN stacks are powerful and popular tech stacks used for building web applications. Which one is better depends on the specific requirements of the project. The MEAN stack is ideal for building large and complex applications, while the MERN stack is perfect for building fast and lightweight applications. Developers should choose the stack that best suits their needs and the requirements of their project.
