For me it’s traefik. It’s took me a while to get it working, but it’s actually really easy now. Setting up container access with labels is very convenient!

For me it’s https://nginxproxymanager.com/ it’s just so easy to setup and use. One docker command and you’re up and running with a nice webinterface to manage access to your docker instances with ssl. I heard good things about Traefik too but I have no personal experience with that one. NPM does everything I need and if it ain’t broken… :)

Caddy. I started with Nginx on my VPS. Then I heard about this new tool caddy. Sounded fun, but whatever. Then I switched VPS (and also Debian to Arch), decided to try caddy and loved the simplicity of it. All the configs are clear and make sense, far more than with Nginx. Super easy SSL is a nice bonus.

Nowadays I have a home server, and user Caddy there as well.

I use NGiNX and have ever since I started. It just works and is easy to configure.
