The short version

  • Each has a real cost: Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer; npm private packages require a paid user or organization account; the free registry publishes publicly only
  • They diverge on capability: Caddy covers Automatic HTTPS, npm covers Package installation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Caddy

  • Smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

npm

  • Private packages require a paid user or organization account; the free registry publishes publicly only

Answered from the vendors’ own pages

Caddy: Is Caddy free?
