I have, I set it up around 6 months ago on a couple of my own personal sites, and it seems to work pretty well. It took a while to figure out the right way to configure it for multiple site hosting, but it has been pretty trouble-free. The cert registration and renewal was really slick. If you want to see it "in action" on a single EC2 instance: https://pythoneers.org/ https://pythoneers.org/ I used an Ansible role to provision it, antonier77/caddy-ansible and it has worked nicely. But, as another comment mentioned: If you are in an AWS load balancer, you probably want to use the AWS certificates.
