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

Cloudflare

  • Free tier limited to basic features (no advanced analytics or premium features)
  • Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
  • Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
  • Geographic coverage limited to announced 330+ cities (may not cover all regions globally)
