I am immediately suspicious of this because HTTP/2 only operates over HTTPS. So for them to market this webserver as being special because it defaults to HTTP/2 over HTTPS is the sort of thing a snake oil vendor would do. Also completely unfond of the license. "Caddy is amazing because it has 3 line config files!" So what? That's only appealing to people who are afraid of editing config files. Here's a harsh reality for the developers (who probably won't see this, ah well), but "config files" are not worth $25/mo or whatever the full scale commercial costs of this are. Do the developers think that their target audience are incapable of configuring traditional webservers? Just because you pour your blood sweat and tears into a thing doesn't mean that thing is worth any money.
