I'm in the middle of making a small website to document some recent travels and I just ran into this problem. I looked at SSI but as you said elsewhere it needs to be configured and then I lose hot reloading support.
So what SSG are you using? I was going to just make some jinja templates that I re-render with my own script, but it would be great if there was something that supported this out of the box without going crazy far up the complexity ladder.
Not OP, but I really like https://www.getzola.org/ because its a single binary (I switched when I realized I could no longer easily build my Jekyll setup locally), has templates that make sense to me (i.e. similar to Jekyll), and hot reloading.
Depends on your language of choice. Personally I use Eleventy[0]. Written in JavaScript (so you'll need node & npm). Has very minimal default settings but highly configurable. Pick your templates or just use markdown if you really want. Hot reloading is enabled by default.
I'm partial to mkdocs. It's designed for documentation sites, but the mkdocs-material theme provides enough functionality to make it well-suited for blogs and adaptable for almost anything.
