Technically, yes. There's another web engine I can't recall the name of, but it's less advanced and comes in a browser less modern than most. And there are terminal-based browsers, but nobody wants to use those because no pics.

So basically no.

Well someone IS making a web-browser by using the Servo-browser engine called "Beaver browser"
