🔒 Setting Up Headscale & Tailscale on NixOS: A Zero-Trust Networking Guide for ❄️ NixOS - YouTube

In terms of setup, Caddy is a lot simpler in syntax, but you will find more tutorials for Traefik and it has better integration with Docker. You can add labels to a container and Traefik uses that as config, whereas in Caddy, you need to set up both the container and the config file. If you want to drop a service, then it is easier in Traefik for this reason. But with decent Nix code, you can basically replicate this in Caddy. Once you set them up, they're pretty much the same. I've seen some people saying Traefik is faster, but realistically, I don't think it's meaningful.
