Whatsie is a desktop WhatsApp client for Linux that wraps WhatsApp Web in a native application shell built with Qt.
The tool solves the problem of WhatsApp Web being confined to a browser tab by providing a dedicated desktop window with native integration. It uses Qt 6 to create a lightweight wrapper around WhatsApp Web that avoids the overhead of Electron, allowing the application to start quickly and consume minimal resources while preserving the full web experience.
Whatsie suits Linux users who want WhatsApp on the desktop without running it in a browser tab. It is particularly valuable for those who need native notifications with contact avatars, system-tray integration with unread badges, and proper downloads management. The tool includes features like app-level passcode locking, theme synchronization with WhatsApp Web's appearance, voice and video call support with screen sharing, privacy controls for camera and microphone permissions, and HTTP or SOCKS5 proxy support. Users concerned about privacy can enable privacy blur to hide message content until hovering, and the application includes a built-in bug reporting flow that collects diagnostics while keeping messages private.
The project shows consistent maintenance with regular updates addressing both feature additions and bug fixes. Development activity demonstrates responsiveness to user-reported issues and a commitment to improving desktop integration across different Linux environments, including support for Wayland through the desktop portal. The maintainer actively incorporates user feedback into the roadmap and maintains clear documentation of the application's capabilities and limitations.
