Opera and Brave are both chromium-based, rather than just using the blink engine. The official webdriver plugin for opera [1], published by opera, refers to their browser as "chromium based". The brave browser [2] is open source and you can see it syncs from Chromium

Opera's built on top of the Chromium content API (approximately Blink plus things like networking, some OS integration stuff, etc.), rather than a fork of all the UI code; the UI is a completely separate implementation and shares nothing (and this is very obvious if you look at early releases of Chopera, with it having much fewer features than Chromium of the same period).

Not completely true, many "model" part is shared with Chromium code (given the liberal license) while "view" part can be different.
