A coworker of mine dislikes it as it bundles everything into a single binary. For example, to have ACME DNS-01 challenges for certificate issuance working, I need to compile in a Google DNS-specific plugin.

But then it... just works. Try the same with most other web servers/proxies and you're in for a world of pain. Having this much functionality bundled into a single binary is as much a curse as it is a blessing.

That said, having your own little 'Cloudflare Workers' in the form of Nginx Unit with wasm sounds great. Not sure Caddy can do that.
