If you want to use no-Javascript browser as well, this browser prototype [0] is getting pretty good too. It's developed by Dioxus, a GUI framework in Rust, as part of its native renderer which seeks to create their own alternative to Skia, similar to Flutter, but it'll work on the web as well with HTML and CSS standards unlike Flutter web which is just a canvas.

It's also a from scratch implementation, sort of, using existing Rust crates like stylo (which servo also uses) and taffy, but it doesn't rely on any code from existing browsers such as Chromium, Gecko or WebKit.
