Altus

Altus is a free, open-source desktop client that brings WhatsApp Web functionality to Windows, macOS, and Linux. Built with Electron, it provides a dedicated messaging environment without requiring an open browser tab. Users can connect multiple WhatsApp accounts and access them simultaneously through separate tabs. The application supports native desktop notifications that open the corresponding conversation when clicked. An online indicator helps identify contacts who are currently available. Altus includes a built-in dark mode and a theme customizer for changing interface colors. Advanced users can also create custom CSS themes. System tray integration allows the application to continue receiving notifications while minimized.
