I had been using Nginx and LetsEncrypt for years and while it worked well most of the time, sometimes it was a bit of a pain, especially due to the verbosity of the Nginx config file. I was using both of them in docker containers and that requires you to have 3 specific environmental variables set for each container.

I tried using Traefik, and while concise, it was still a bit confusing.

I finally decided to give Caddy a try a few months back after hearing about it for years. I'm disappointed that I didn't try it sooner because it's so freaking simple to use. I rewrote my entire docker-compose file to use it because it's that simple. I love how it takes literally 3 lines to create a SSL secured reverse proxy.
