About This Free Course
We built the bestselling React course on Udemy - this course now allows you to take your React knowledge to the next level and build fullstack web apps based on React, NodeJS, MongoDB and Express!
Building fullstack applications (i.e. frontend + backend) with the MERN stack is very popular - in this course, you will learn it from scratch at the example of a complete project!
MERN stands for MongoDB, Express.js, React.js and Node.js - and combined, these four technologies allow you to build amazing master go golang build scalable web applications.
In this course, we'll build an entire project and you will learn how these different technologies work together step by step. We'll first have a look at all the individual building blocks, so that we then can also combine them all into one amazing application by the end of the course.
This course also doesn't stop after the basics - instead, you'll also learn how to add file upload, authentication, authorization and how to deploy your application in different ways to different hosting services.
This course is taught by two instructors - Max (React.js, Node/ Express) and Manuel (MongoDB) who have years of experience of working with these technologies and teaching them to other people. We took and combined our experiences to deliver you the best possible MERN stack course you can find out there.

Who Should Take This Course
"React, NodeJS, Express & MongoDB - The MERN Fullstack Guide" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a strong rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
