Whatsie

Whatsie is a native Linux desktop client for WhatsApp Web, built on Qt 6 and QtWebEngine. It brings WhatsApp out of the browser tab and into a proper desktop application — lightweight and fast, with system integration, privacy controls, and customization options a plain browser cannot offer.

Core features:

• Light, dark and follow-system themes, kept in step with WhatsApp Web
• Native desktop notifications with contact avatars
• System-tray icon with an unread badge, mute and do-not-disturb
• Voice, video and screen-share calls (Wayland via the desktop portal)
• Built-in download manager with history; drag-and-drop and paste of attachments
• Spell check for your system language
• App lock with a passcode and configurable lock on start, on hide, or after idle
• Privacy blur to hide message text and media until you hover

More controls:

• Per-site camera, microphone and location permissions
• HTTP / SOCKS5 network proxy with authentication
• Autostart at login and start minimized to the tray
• Single instance with multiple-account profiles
• Zoom and interface scaling, plus a keyboard-shortcuts sheet
• One-click bug reporting with diagnostics, no messages included
