The friendly licensing (Apache v2) is important too, especially w/ Caddy's modular architecture (single, static binary compiled for any platform).

Meaning ecosystems around Caddy to make it even simpler and more secure, e.g. keep your server private while serving Internet clients. So VPNs like Tailscale (1) or zero implicit trust like OpenZiti (also Apache v2; (2)). Similar to what we have seen with open source k8s ecosystem for example.
