Is there a static site generator out there that doesn't require a ridiculous build process every time I do an update? Inevitably, when a new "hot" SSG comes on the scene, I try it, and then go back to compare it to the old "hot" SSG from 2 years ago. Yet, I can never get the old test site I set up running again without massive annoyances. This has happened multiple times. As far as I'm concerned, there's zero reason…
Use any SSG not written in javascript and you'll be fine. Hugo, Zola, Jekyll, etc. Though if I was starting from scratch I might avoid Jekyll just because of the Ruby dependency.
Commonly stated but not actually true. For example:
