Real-Time Code Collaboration System Using MERN Stack

Real-time collaboration tools have become essential in modern software development due to the rapid growth of distributed teams, remote working environments, and online education platforms. Traditional version control systems allow collaboration but do not support real-time visibility of code changes, often leading to conflicts and reduced productivity. This paper presents the design and implementation of a real-time code collaboration system using the MERN stack. The proposed system allows multiple users to simultaneously write, edit, and view source code in real time. Secure user authentication is implemented using Clerk, and MongoDB is used for efficient and scalable data storage. Event-driven communication ensures low latency synchronization across all users. Experimental results demonstrate improved collaboration efficiency, reduced conflicts, and reliable performance under multiple concurrent users.
