Tell me about it.

My simple SSG Next.js static site loads much slower than my Jekyll site on GitHub pages.

And I can't figure out how to improve its speed or disable the "ISG" feature that I believe is to be blamed for the poor performance.

Not defending NextJS, I'm pretty out on it myself, but ISG requires a server to run. It pregenerates static content for defined pages and serves that until revalidating. If you've built a fully static bundle, nothing exists that would handle that incremental/revalidating logic.

I understand that ISG requires a server (Node.js runtime) to run it, that's why I want to disable it for my SSG Next.js static site, but I can't figure out how. I just want static hosting like S3+Cloudfront which is much faster.

You need to use static export:

Cool, so that's what I was missing all along!

Unfortunately looks like I can't use it now since I am using `next-plausible` which does require a Node.js proxy...
