My main browser is Librewolf but I keep a chromium browser just in case. Previously used brave but their flatpak is shit. Ungoogled chromium seems ok but it looks like they don’t change much from upstream chromium. Any good chromium browsers which harden their browsers like librewolf does for more privacy?
No, it isn’t, try and see it yourself.

didn’t you read my comment? That whole post is marketing excuses for not being free software.
Try compiling the “source code” they release and tell me if you get a usable version of Vivaldi.
That page is telling you that they don’t want to make anything open source unless they are compelled to by law. And so far, they have not been.
Where do they say it?
It literally says that multiple times. Their UI and “other code” is closed, therefore the browser is NOT open source. Giving the base they started with doesn’t equal a browser, and doesn’t equal you being able to compile the finished product. It’s no more open source than Chrome.
