Collaborative code editors have come onto the scene as instrumental in bringing about live collaboration between software developers—making teamwork smoother and ultimately productivity easier to achieve. The design, implementation, and assessment of a collaborative code editor that combines chat messaging, code compiling, code execution, and real-time code editing are presented in this research paper. The Co-Code Editor performs better than conventional code editors by utilizing technologies like Socket.IO for low-latency communication, Piston API for code execution, and Firebase for quick database operations. Multiple users can edit and review code simultaneously with the collaborative code editor, which improves teamwork and productivity in development projects. Performance measurements illustrate the system’s scalability and usefulness by showing low latency, effective bandwidth usage, and strong support for concurrent users.
