Ask HN: What free or low-cost static site hosting do you use most?

I still use Wordpress and shared hosting for most projects and microsites, simply because it's easiest and I'm not a developer. But I suspect there are better ways to do this in 2016/2017. Especially since I'm prepared to learn more.

Essentials: static hosting, custom domains, html, css, js Nice to have: php, FTP, markdown support

Am I missing out on AWS, Github, Digital Ocean, Heroku?

What are the pros and cons?
