WhosDown is an open-source Windows 10 client for WhatsApp. More specifically, it's a wrapper for WhatsApp Web. WhosDown lets you run the WhatsApp Web application in a self-contained window, enabling you to pin it to your start menu or task bar, devote a second monitor to it, and use other window management tools to manage your WhatsApp session separately from your browser. Additionally, WhosDown doesn't require any specific browser.
Please note, if you are running this on a mobile device, you will either need a second screen (Continuum) or another device with the official WhatsApp app to scan the QR code and log in.
DISCLAIMERS: This is not a native client for WhatsApp. It is a Windows 10 wrapper for WhatsApp Web. This essentially means we are running the WhatsApp Web website in its own window. Due to the limitations of WhatsApp Web, this app does not have all the capabilities you might expect from a native app. The app must be running to receive notifications.
This is an unofficial, fan-made app and is not endorsed or sponsored by Facebook, WhatsApp, or their affiliates.
