Code-Sync Real-Time Collaborative Coding Platform

The rapid growth of remote software development and online programming education has created a strong demand for browser-based environments that allow developers and students to write, run, and review code together in real time. Traditional Integrated Development Environments (IDEs) are single-user tools that offer limited support for simultaneous multi-user workflows. To address this problem, a Real-Time Collaborative Coding Platform named CodeFlow is proposed. The platform is designed as a web-based system that enables multiple users to simultaneously edit, execute, and review code within a shared browser-based environment. Users can create or join rooms, collaborate on code in real time, and submit solutions to programming challenges that are evaluated automatically against predefined test cases. The system is developed using modern web technologies including React.js with Monaco Editor for frontend development, Node.js with Express.js and Socket.io for backend services and real-time communication, and MySQL with Sequelize ORM for database management. The platform includes features such as real-time code synchronisation, room management, code execution sandbox, challenge management, and an analytics dashboard. The proposed system simplifies collaborative coding by providing a structured digital environment where developers, students, and instructors can work together efficiently. The platform improves accessibility for learners and helps instructors monitor and evaluate coding performance in real time.
