Altus is a free, open-source desktop client for WhatsApp with built-in themes and multiple account support, available for Windows, Mac & Linux!

It is made using the Electron framework with HTML, CSS and vanilla JavaScript.

I started creating it in the latter half of 2018 because no other desktop client for WhatsApp had a dark theme or an option for custom themes.

Altus is still regularly maintained, with over 39,000 downloads as of writing.
