This is an honest question, I just don't quite get why there's so much excitement in the comments.
Thanks!
There are many sophisticated static site generators which allow creating and maintaining large complex sites.
There are static site generator CMS apps which provide viable front-ends so that non-technical people can manage content. See netlify CMS.
All content is kept in git with all benefits derived from it.
Netlify hosting is free, simple to set up, secure by default, and provides lightning fast access in a “set it and forget it” manner.
To update your site, push to your github/gitlab/bitbucket repo. To create a preview of changes, push to a branch.
Form processing, logins etc. are inexpensive easy to set up add-ons.
Static websites are a magnitude faster, less hack-able and worry-free.
It’s a really sweet spot.
Heroku could be used for this but the free tier is limited.
Ease of use vs flexibility.
Right now, I push for static site solutions over dynamic ones where possible because hosting is an order of magnitude simpler and there's way less that can go wrong.
