The developers have to adapt to and work with a new technology that delivers faster, better results. In 2025, the wide adoption of AI technologies across companies has sparked a conversation about the traditional MERN stack.

The Question of Learning MERN Stack in 2026

​

New-age developers, especially freshers, have been asking whether learning the MERN stack is relevant in 2026. It consists of traditional frameworks such as MongoDB, Express.js, React, and Node.js, which are readily automated by AI-assisted coding platforms like GitHub Copilot. However,

, Node.js remains the most widely used coding framework worldwide as of 2025. The numbers show the relevance of

MERN stack courses

in the modern day. However, instead of getting anxious about whether AI will replace MERN stack developers, students and new developers should be more curious about how they can reprise or modify their role in an AI-first world.

​

The relevance of MERN stack training courses stems from the rapid adoption of AI across companies. However, AI is only transforming the development workflows, where practical knowledge of the traditional tech stack can be immensely helpful. We will discuss the relevance of learning the MERN stack in the modern day in the following sections.

Why are Students Sceptical About MERN Stack?

​

The students’ doubt about the MERN stack today stems from the rapid adoption of AI coding tools. The tech stacks of MongoDB, Express.js, React, and Node.js are actively maintained, adopted, and widely integrated. However, with the advent of AI-embedded coding platforms such as GitHub Copilot, non-developers can prototype applications and software systems. Experienced developers, on the other hand, can ship code much faster. However, it's tough to ignore some key realities of these AI tools:

​

• Developers use AI primarily for syntax and boilerplate code, but struggle with complex logic and architecture.

• Developers are still required to design application workflows, address security and performance, and debug key issues.

• Even after generating code with AI, developers ensure it is refined through human validation.

​

These factors still keep the
