I have been thinking exact same things sometimes, I want to view some random websites, but I don't know many anymore, only some tools, which is great, but not exiting.

I think it's cause there's no good Content Management system, there's wordpress, it's still very popular, but kind of bloated and hard so manage.

I haven't found any Headless CMS, that I could just self host and attach the data to my website :/
