Whatly

Whatly is a native desktop wrapper for WhatsApp Web, built on Qt

and QtWebEngine. It brings WhatsApp out of the browser tab and into a

proper desktop application with system integration, privacy controls, and

customization options unavailable in a plain browser.

This is a fork maintained by Ángel Guzmán Maeso, based on the original

WhatSie created by Keshav Bhatt and released under the MIT licence.

Core features:

Multiple WhatsApp accounts: as separate windows or as tabs in one window, each with its own session and settings

Scheduled messages, sent later and delivered on the next launch if the app was closed when they came due

Fourteen chat themes, a chat wallpaper and custom CSS

Privacy blur that hides the chat list and open conversation until you hover

Choose the font family WhatsApp Web renders in, plus an adjustable interface font size

Spell checker with 31 languages, several checked at once

App lock with PIN protection and a configurable auto-lock timeout

Light and Dark themes, optionally following the system preference live

Desktop integration:

Native system notifications and custom in-app notification popups

System tray with an unread badge, an optional monochrome icon and a connection-status indicator

Unread count shown on the taskbar (Unity LauncherEntry: KDE, Dash-to-Dock and others)

Connection watchdog that reloads a stalled session, and optional automatic reload after a page crash
