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
- Global keyboard shortcuts and a built-in download manager
- Per-session audio mute and notification suppression
- HiDPI/4K scaling, configurable zoom and a custom user-agent string
- Runs on Linux and Windows (plus an experimental macOS build); interface translated into 22 languages
