WhatsApp UI is an application inspired by WhatsApp Web, initially focused on replicating the interface but later enhanced with Firebase integration, bringing full group chat and authentication features. The platform allows users to log in via Google account or email and password, create and join groups, send and delete messages, and edit group information such as name and description.

The app features dark/light mode toggle, participant display, real-time message viewing, and a fully responsive layout, providing a chat experience similar to WhatsApp Web. The interface is intuitive and functional, perfect for learning and practicing real-time communication app development.

The development stack includes Next.js for application structure and rendering, Firebase for authentication and real-time database, Styled Components for styled and responsive interfaces, and React Icons for interactive visual elements.
