This is an homage to the 90s only in the sense that public HTML hosting was more popular in the 90s. Everything about this seems like a modern project (in both design and ideals) with a very inaccurate "retro" coat of paint. - Site makes use of HTML5 and modern JS. Why bemoan modern frameworks and then use modern, bloated elements? - Why is there a completely modern register/sign in section in the middle of the home…
It feels very contrived, as if someone has seen a handful of screenshots and tried to describe it to someone else, rather than a clear (or just well researched) memory of what the mindset, trends and limitations really were around web design 30 years ago.
It is intended to provide easy hosting, which many people need, and to encourage people to work on their own computer, rather than use web based tools, so it will have upload/validation, etc, but never editing or change your html in any way.
