Traditional programming environments require users to install Integrated Development Environments (IDEs) and configure compilers locally, which can be time-consuming and device dependent. This paper presents an Intelligent Web-Based Code Editor designed to allow users to write, compile, and execute programs directly from a web browser without requiring local installation. The system is developed using the MERN stack, which includes MongoDB, Express.js, React.js, and Node.js. The platform supports multiple programming languages such as C, C++, Java, Python, and JavaScript. It provides features such as syntax highlighting, real-time output display, secure code execution through sandbox environments, and user authentication. The system improves accessibility for students, developers, and educational institutions by providing a centralized coding platform that can be accessed from any device with internet connectivity. The proposed solution reduces system dependency, improves coding efficiency, and enhances learning experiences for programming students.
