Description: "Caddy is a general-purpose web server for Windows, Mac, Linux, BSD, and Android. It is a capable but easier alternative to other popular web servers."
I use caddy on all my personal websites because it can do automatic HTTPS via Let's Encrypt. Caddy obtains and manages all cryptographic assets by itself and completely automatic. Also it's lightweight and easy to use. I'd like it in Solus because I also use it for developing my sites.
Thank you. :)
