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

You.com

  • Pricing tiers beyond the pay-as-you-go table are not published and require contacting sales for volume discounts.
  • Finance Research API is priced significantly higher than the other endpoints, at $110 per 1,000 calls.
  • No self-serve dashboard details are published for managing enterprise zero-retention settings.
