Whale Panel is a comprehensive admin dashboard system for managing X-UI panels with role-based access control (SuperAdmin and Admin roles). The application features a FastAPI backend with SQLite database, a React/TypeScript frontend, and a Telegram bot for VPN reseller functionality. It provides unified management of multiple panel types (3x-ui, Marzban, Guard, Tx-ui) including user management, traffic monitoring, and system statistics. The architecture follows a monolithic design with clear separation between API services, business logic, and presentation layers.
