I don't think Vivaldi is open source. But if Brave's features are so bad that you're willing to switch to an closed source browser, why not switch to Firefox?

So when I'm using OpenBSD, I use Firefox exclusively. On my Mac, I use Safari 99% of the time, but I do have Firefox installed and use it for some things, but when I need a Chromium-based browser, I use Vivaldi, instead of Chrome or Brave.

EDIT: It looks some of Vivaldi's source is available FWIW, https://vivaldi.com/source/

The UI is closed source.
