That may seem like an oxymoron, but I’m looking for some sort of server that I can self-host where I can edit blog posts and whatnot, but that then deploys to something like neocities (or any other pure static host).
I’m not finding anything, but maybe it’s a thing and I just don’t know what it’s called?
grav is another option for what you were looking for. cli with optional web interface. run local and generate static sites or on a web server (like a traditional cms) https://getgrav.org
for a static site generator that runs locally (with local or git storage), check out https://jamstack.org/generators/ for lots of other options.
