Abstract: As collaborative development gains prominence in both academic and professional software environments, the need for intuitive, accessible, and real-time programming platforms becomes essential. This paper presents a minimalistic, browserbased code editor that enables synchronous programming collaboration through live code sharing and execution capabilities. Built using the MERN (MongoDB, Express.js, React.js, Node.js) stack and Socket.IO for real-time communication, the platform allows multiple users to write, view, and execute code together seamlessly. Designed with simplicity and performance in mind, the system enables peer coding, interviews, and learning scenarios with instant feedback and interactive features. This paper details the architectural framework, user-centric interface, and implementation of the proposed system, supported by a review of existing tools and their limitations
