> For example, if you have 2 instances of Caddy in production and 3 web developers using Caddy locally to build your website, that's 5 instances. (A single developer who starts multiple instances of Caddy temporarily in local dev can still just count as 1.) If you also spin up a maximum of 3 containers at a time with Caddy binaries inside it, that's a total of 8 instances.

This reminds me of Microsoft’s CAL licensing scheme(s). Those were ALWAYS confusing, and [in my experience] rarely followed correctly.

I'd wager this won't generate any meaningful revenue, but may open doors for legal action of people in violation. Hopefully that's not the goal.
