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

D-ID

  • Pricing details are not published on the main pricing page; specific costs for Trial, Lite, Pro, Advanced, or Enterprise plans are not disclosed
  • Multiple pricing sections (Studio vs API) exist but neither displays actual dollar amounts or feature breakdowns
  • Enterprise pricing requires contacting sales directly
