Whatsie is a web application desktop wrapper designed to turn web interfaces, specifically messaging services, into standalone desktop applications. It provides a dedicated window environment with a custom icon and system tray integration.
The project includes security and privacy layers such as password-protected session locking with automatic timeouts and the ability to purge persistent application data and web caches. It also features native hardware permission management for controlling camera and microphone access.
The application supports native system notifications, file download handling, and visual customization including time-based theme switching and page zoom configuration. Administrative tasks and application state management are accessible through a command line interface.
