Perhaps mataroa.blog or blot.im?

Mataroa is freemium ($ for auto-export and custom domain features, all else is free). Blot.im is paid, like a CI/CD that turns a git repo or a folder in your Dropbox or Google Drive into a static site.

I've not used mataroa, but did use blot.im when I was blogging.

Otherwise I second the recommendation for a static site generator, like Jekyll or Hugo.
