Real-Time open Board Project

Realtime OpenBoard is a browser-based collaborative whiteboard application developed to enable real-time visual interaction among multiple users. Designed using modern web technologies, including HTML5, CSS3, JavaScript, Node.js, and Socket.io, the system enables users to draw, annotate, and share ideas synchronously on a shared digital canvas. It includes essential features such as freehand drawing with customizable tools, sticky notes, undo-redo functionality, and board download capability. Socket.io enables efficient real-time communication by transmitting drawing events instantly across connected clients, while the HTML5 Canvas API provides smooth and responsive rendering of user input. The application is lightweight, does not require installation or login, and is accessible from any modern browser, making it ideal for educational, professional, and remote collaboration contexts. The project emphasises usability, modular design, and performance, with future scalability in mind. Rigorous testing was conducted to validate real-time synchronisation, functionality accuracy, and cross-device compatibility.
