To add to this, there’s Sourcehut Pages too, which is a free software code forge unlike Github. Sourcehut is very minimal and doesn’t even use Javascript in its interface. The landing page for Sourcehut declares in no uncertain terms:

Absolutely no tracking or advertising

I can’t say I’ve used the Pages functionality myself as I already have my own website hosting, but the quick-start guide seems pretty approachable: srht.site/quickstart

It might be easier to use Hugo to build the website files if you don’t want to learn HTML/CSS. If you want to use a custom domain name, the steps seem simple enough: srht.site/custom-domains

Sourcehut is in Alpha at the moment, so it’s free, but they intend on charging for it once they’re out of Beta. You can optionally pay for it now, and the prices are pretty reasonable.
