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

WSO2 API Manager

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately
