I appreciate Ladybird's initiative. But if they work with Servo, Ladybird can build the browser and Servo can focus on the engine. Also we can avoid C++ nightmare. Everybody wins.
Ladybird seems to have more momentum and be further along in development in my testing of visiting random websites. This may or may not have something to do with developer velocity of each language, genuinely I don't know but I think it's worth considering.
Regardless, from what I've gathered, Ladybird is going to ship of theseus their way into memory safety. It's not announced what the C++ replacement language will be, but they are working towards that.
In what way? Rendering pages CSS compatibility? I tried servo on Windows and it worked, not so much for Ladybird - granted, I wasn't feeling up to task of compiling it for Windows.
Ladybird doesn't support Windows yet because most developers use Linux or macOS. Ladybird has been progressing faster when it comes to CSS rendering and JavaScript support.
