That website lists Hugo, the static site generator. What kind of self-hostable service does Hugo provide??? Confusing info like this makes me doubt the rest of the entries on that page.
I can tell you that technically Hugo has to be somewhere you control to generate a website, but I don't see the point in that discussion.
The list I can see on the site seems to be of tools you can self host or can help you create something that you can self host. That's it. It doesn't make sense to blame a site because a comment on HN didn't correctly describe the content of the website... like, the problem is the comment, not the site.
