Any Tool for generating Static WordPress websites?

[JDHD]

Wanna make a notion on all possible Tools available for Generating Static Wordpress sites.
One of my co-workers found Flatsite.com - it’s an all in one-platform used to build and manage WordPress websites.
Could you share your views about it?
Any alternatives?

It offers a maintenance-free approach to managing your sites, with FLATsite.com automating updates of WordPress core files and plugins so that you don’t have to. Your server can be located anywhere and hosted with any hosting provider. If you don’t have hosting or don’t remember your server address you can add this later.

Hugo is an elementary static site generator in terms of installation and navigation. The entire process is backed by detailed documentation to help you set up and run the generator flawlessly. Hugo has an extensive library of pre-built themes that makes it significantly easy to design your site as you wish.

Another brilliant feature of Hugo is its fast build speed. You can get any static site up and running in the shortest possible time. Moreover, the site has a straightforward dashboard that allows quick editing and changing themes without rebuilding the entire site.
