Wave is an unofficial WhatsApp Web client for Linux. It wraps WhatsApp Web in a minimal Electron app so you get a real desktop experience: minimize to system tray, unread badge, native notifications with sound, and window size/position remembered. Built with security in mind (sandboxed, no unnecessary permissions) and with keyboard shortcuts and single-instance behavior so it feels like a native app. One-line install, AppImage, no browser tab required.
