muon

I didn’t understand what this meant until I dug up more information, especially since I thought Brave was already based on Chromium. Turns out that so far only the browser engine was Chromium based. Now its user interface is also transitioning from an in-house open source framework called Muon [1] to Chromium. This is what an announcement more than six months ago (from March 2018) [2] says: > Brave for Windows, macOS, and Linux currently use the Chromium rendering engine, but (unlike Brave for Android) it uses a custom HTML and JavaScript user interface. Technical readers will know that we call the runtime for this user interface Muon, which is a more secure fork of Electron, and which therefore combines Chromium and Node.js to enable applications built using JavaScript and HTML user interfaces and Node modules for the application logic.

Brave moved away from that to Muon[1], which (IIRC) was originally very close to Electron, but now[2] actually is just a minorly-patched version of upstream Chromium. They've since moved from Muon to Chromium for the browser chrome[3]. [1]: https://github.com/brave/muon/blob/master/README.md [2]: https://github.com/brave/muon/blob/master/docs/tutorial/movi...

They run on a fork of Electron: https://github.com/brave/muon https://github.com/brave/browser-laptop
