I haven't heard of HardyPress, but I will take a look at it.
I know about projects with Wordpress REST API as a backend with static page generators. This is similar approach, I think.
Thank you for sharing.
Yes, the WordPress REST API is another option, but it isn't used with HardyPress. You build your site like you normally would (besides not being able to use every plugin) and it deploys a static version of your WP frontend. Yes, this means your templating is still done in WP. We settled on using Timber to make that part less painful. :)
