Name me an OS that doesn't need an OS to build it.

It needs a very special OS: "git, lua, curl, a sha256 utility, standard compression utilities, and an x86_64-linux-musl cross compiler"

Of those, only an x86_64-linux-musl cross compiler strikes me as even remotely unusual, and that's still widely available.

You mean besides just install the relevant packages by: "pacman -S git lua52 gzip coreutils gcc musl" on a standard arch install? (presumably similar for other distros)

That's... a list of things I already have installed, the Lua executable aside. This is a pretty normal-looking dependency list for native C software. Are you perhaps not used to building C software?

Indeed, it uses a custom Wayland compositor. To me it looks like using a minimal Wayland compositor would fit the project better than using X. The same could be said about using Netsurf.

Velox appears to be a Wayland compositor, and supports Xwayland.

um, it says if you have the libs and configured compiler, you can build it.

there's also nothing stopping you from doing static builds of whatever application you want to include in your OS.
