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

Metricool

  • Full Twitter/X analytics and post approval workflows are locked behind the Advanced plan.
  • Unlimited scheduling on paid plans is still capped by an undisclosed fair use policy.
  • Free plan is limited to a single brand and 20 posts per month.
  • API access is only available on the top Advanced tier.
