I recall eleventy being pretty good.

I had one issue with it, re how it generated links, that didn’t match how I needed it to in order to migrate my site, which was a dealbreaker for me. But other than that, it was solid.

I despise jekyll, purely from the standpoint of the state of their documentation.

There was another, that was extremely lightweight and configurable, at the cost of requiring much configuration - I think it was called “metal” - if I can find it I’ll report back

Edit: Hexo and Metalsmith. Hexo scratches my javascript itch; metalsmith is extremely versatile - it’s more of an erector set than a finished thing.
