Mar 22, 23  |  Bakhtain Afzal

You've got a great idea, but what if you lack the tech stack to effectuate your vision into a plausible solution? Consequently, your hard work, time, investments, and dedication would go down the drain.

As a ride back into the old town, yes, the tech-savvy had a little world of tech stacks, mainly consisting of LAMP or a few other stacks that initially served the same purpose. Technological advancements have already dropped our jaws, but we've only started.

Along that, there's a plethora of possibilities these advancements invite. And, translating your once-termed futuristic concept can now be a realistic software solution. For example, web, MERN and Full stack web development are great options.

But how do you select the best out of both? As your savior, this article walks you through everything from an overview of stack and MERN, MERN Stack vs Full stack comparison, and the benefits to stack coding.

Overview Of Stack?

A stack refers to a group of interdependent programs that run in tandem to facilitate the operation of an application. It typically includes components, such as an OS, architectural layers, protocols, runtime environments, databases, and function calls, which are arranged in a hierarchical structure. 

The lower-level components of a software architecture communicate with hardware, while the higher-level features carry out the actual work for the user. Components interact with the program directly via a stack of complicated instructions.

What Is MERN?

MERN is a widely-used JavaScript stack in the software engineering industry. The MERN Stack is a set of cutting-edge technologies for developing scalable software. A wide variety of frameworks, databases, libraries, and other tools are used to create these applications.

It is built with several freely available libraries and frameworks, including MongoDB, React, Node.js, and Express.js. These parts contribute to full stack framework support for coders.

The MERN stack comprises the following technologies:

  1. Node.js

Being developed on the V8 JavaScript engine of Chrome, Node.js comes with a JS runtime while bringing it to the server.

  1. MongoDB

This open-source platform and document-based database offer the tools and services required to quickly create distributed applications at superior performance and scalability.

  1. React

It creates user interfaces, leading to a front-end JavaScript library. It’s mainly utilized when building interactive web apps and user interfaces efficiently without heavy usage of coding. 

  1. Express.js

This is a minimal yet, fast website framework used for Node.js.

MERN stack stands greatly resembling MEAN stack - another favored tech stack. The only difference is MEAN's use of Angular tools for front-end web app development. At the same time, MERN uses React. 

A few examples of widely known enterprise apps created with MERN are WhatsApp, Netflix, and Dropbox.

Benefits of MERN Development

Here are the top benefits of MERN development:

Flexible Data Model

MERN coding provides a flexible and dynamic schema. This also comes with GUI and other command line tools. Additionally, developers find the MERN framework to be faster and better and the option to customize application development solutions.

End-to-End Development

Web development MERN stack creates a stack development environment for developers where they can create fully scalable applications leveraging top front-end development tools.

MongoDB, as a development solution of MERN, allows data storage in JSON file documents. And due to this, the developers find combining and storing data with MERN more flexible. 

Software Scalability

Web development MERN stack technology stack offers the best scaling solutions and development flexibility. Meanwhile, the developers can follow a proper consistency chain among other data centers.

What Is a Full Stack?

A "full-stack" developer is proficient in both - the front- and backend technologies used to build an application or website. Full-stack engineers are experienced in all aspects of an application's infrastructure, from the front end to the back end, including the server, the application programming interface (API), and the database. That's why they call them "Full Stack" developers.

Here, the programmer creates the best possible user interface, user experience, and backend using various technologies. The developers start from square one and work up to handing over the fully functional website or app.

Full-stack web development includes the following software solutions:

  1. Front-end

This includes JavaScript, HTML5, Ajax, and CSS.

  1. Backend

This part of development includes using Python, PHP, Django, NodeJS, etc.

  1. Database

Clusters, SQLite, MongoDB, Postgres, etc., are used in database development.

  1. Mobile Apps

It covers both Android and iOS.

  1. DevOps

SDLC creation.

A full stack developer oversees the project layout. Developers working with the And today, various businesses are desperately attempting to recruit stack developers capable of creating a whole website or app from the start without any breaks in the process.

Benefits of Full-Stack Development

Here are the benefits of full stack web development:

Expanded Technical Expertise

While hiring a Full stack web development agency, you can avail yourself of the ultimate benefit of expanded technical expertise. You get increased productivity without pausing your workflow due to a specific technical difficulty. Moreover, you've to sit with a minor team of developers.

Quick Development Process

This is more efficient and quick than other types of development. Since you get it all from a smaller team that does it all.

Effective Management

The difficulty of hiring developers is lessened with full stack web development, which simplifies team administration. For the development, you will need to recruit a few developers that align with the stack framework. As a result, working in a small team fosters better communication, greater transparency, and open exchange of ideas.

Easier Switching

A full-stack developer is adaptable enough to transition between various technologies when necessary. This is crucial while working on a big project because A/B testing is more valuable than planning in these situations in the scenario of a stack framework.

What Is the Difference between MERN Stack and Full Stack Development? MERN Stack vs Full Stack

The following are the differences that contribute to the comparison of the MERN stack vs Full stack:


This factor is a primary contributing feature when it comes to comparison of full and MERN stack. In stack development, you should expect a medium level of productivity. 

Whereas web development MERN stack offers a lower productivity ratio due to the complexity of use it provides when compared to full-stack coding.

Third-Party Support

Full-stack offers different libraries, such as jQuery and LESS. Meaning it's more flexible with third-party support, i.e., its libraries. MERN coding, on the other hand, requires developers to integrate additional libraries for completing similar tasks - that you can achieve through stack coding with total ease.


In a full stack framework, developers are required to follow a 3 tier web architecture. Meanwhile, MERN coding offers a smooth UI rendering.


In full-stack architecture, you, as a developer, should expect standard web and app development scalability. Contrastingly, in MERN coding, you should expect the tables to turn, where you can avail of a high level of project scalability.

What Are Full-Stack Developer Technologies?

  • JavaScript and its ecosystems, such as NodeJS and ExpressJS. The Node platform is an open-source, cross-platform runtime environment for developing server-side tools and JavaScript applications. Knowing how to use the command line and tools like Node Package Manager (npm) is crucial.
  • In particular, Java was designed to operate in a server environment. Spring and Java Server Faces are two of the most well-known frameworks written in Java.
  • Simply put, Python is the language of choice. It may be adjusted to fit your needs and is simple to implement. For the backend, we rely on Python frameworks like Django and Flask. Websites may be built quickly with the help of Django, a web framework written in Python. It's open-source, so anybody may contribute to it, and has a sizable and active user base.
  • Regarding Windows-based backend development, C# is often regarded as the most popular language for stack coding.
  • Besides PHP, Perl, and Ruby are some more options.

Is MERN in Demand?

Developers fluent in JavaScript are in high demand as MERN development is monolingual. Using trained personnel fluent in MERN has far greater returns for businesses. Compared to employing many specialists for various technologies, this approach is more efficient financially and time-wise.

The increasing prevalence of JavaScript-based apps bodes well for MERN\s widespread adoption. It's the most popular choice since it can be used for both the user interface and the underlying infrastructure, eliminating the need to switch gears constantly. Developers must overcome the difficulty of knowing all the languages involved in a tech stack that employs numerous coding languages to construct apps successfully. 

However, MERN is different. Since the stack framework is primarily JavaScript-based, developers must become fluent in that language.

Is MERN Stack Equal to Full-Stack?

Yes, the MERN framework is equal to full-stack. Using the tried-and-true three-tier architectural design, MERN consists of a front-end display tier (React.js), an application layer (Express.js and Node.js), and a database tier (MongoDB).

You may use MERN to create anything; however, it shines in scenarios with lots of JSON, is native to the cloud, and has dynamic web interfaces. Examples of MERN framework use cases include workflow management, news aggregation, to-do applications, calendars, interactive forums, social goods, and others.

Is Full-Stack in Demand?

The many talents a full-stack developer may contribute to a task make them in great demand. Developers that work "full-stack" have expertise in both the front and back end. This allows them to create a fully functional web application. Developers that work on the entire stack, from the server to the client to the database, must be well-versed in all of these areas.

They should also have no problem switching between several programming languages and frameworks. With their versatility, full-stack engineers are an invaluable addition to any web development company.

Full-stack developers are highly sought after because of their expertise in creating comprehensive web apps. They have extensive knowledge of backend technologies such as PHP, Ruby on Rails, and Node.js and front-end technologies such as HTML, CSS, and JavaScript.

The industry tends to favor full-stack developers over those focusing on single-stack components. This is due to the fact that they can work on all facets of a web application, providing a comprehensive service to their clients. The requirement for web application development is expected to increase, leading to a greater need for full-stack developers.

Is Nodejs Full-Stack?

Yes, Node.js is full-stack, allowing developers to benefit from non-blocking programming. The developed programs can then execute several tasks in parallel. This improves the efficiency of JavaScript-only web apps, which leads to a more satisfying result for the consumer. 

Web developers also have access to a vast collection of resources, including JavaScript frameworks and libraries, and are part of a lively community. Because of this, full-stack JavaScript developers will have access to many materials, including communities, forums, documentation, and ebooks, to use as reference materials when writing code.

Which Stack Is Best for Full-Stack?

Node JS and Express.js

Node JS and Express.js are two popular options for stack development. Node JS provides a runtime environment for those who want to use JavaScript on the server. Express.js is an efficient framework for creating web apps built on Node JS.

The MEAN stack combines these two technologies and is a standard option for developing applications from the ground up.


What Does MERN Mean in Coding?

MERN development stands for MongoDB, Express, React, and Node.

Is MERN Still Worth It?

The MERN is an excellent method to train for the in-demand roles of MERN Developer and Full-Stack Developer. Specializing in JavaScript will have access to more sophisticated projects after learning the MERN.

What Is Full-Stack MERN Developer Salary?

An average US MERN developer earns an annual salary of $75,000.

Final Note

Wrapping up the MERN stack vs full stack, both tech stacks are suited to the project requirements. To elaborate on that, you can expect opting for a MERN developer to be a better option if you work on a smaller project.
