it isn't mentioned anywhere but it's chromium based — which is of course is practical, but I wonder how dependent on Google that makes them and other browsers using it
Maybe I’m misunderstanding, but why is this practical? It’s a Mac app, WebKit already ships with the OS and can be easily used with WKWebView. Bundling Chrome is a much bigger app size and much more complicated build setup than importing a class that ships with Cocoa.
Practical because they're also working on adding Windows support. Although it sounds like they're writing everything in SwiftUI and trying to port most of the Swift code to run on Windows? So not necessarily the most practical approach there either.
Not particularly. Almost every browser out there other than Firefox and Safari are using Chromium, Including Edge, Opera, Brave, and Vivaldi, so there's a large enough base that a fork could conceivably be created and maintained if needed.
