GitHub All Releases GitHub issues Donate using Liberapay ko-fi

Altus is an Electron-based WhatsApp client with themes and multiple account support, available for Windows, Mac and Linux!


Altus uses the GitHub-produced Electron framework to wrap around WhatsApp Web and add extra features to it.

  • Multiple Account Support: As of v2.0, you can use multiple WhatsApp accounts simultaneously!
  • Native notification support for all of the platforms. Clicking the notification opens that specific chat!
  • Online Indicator: Shows an indicator at the bottom-left corner of the chats that are online!
  • Dark mode for when you need to chill out your eyes in the night (or even in the day)
  • Custom Theme Support: Write your own CSS theme for WhatsApp or use the in-built Theme Customizer to create a new one just by picking colors!
  • Available for most desktop platforms including Windows (7 or above), Linux and MacOS.
  • Tray icon so you can minimize the app completely and still receive notifications.
