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

Ideogram

  • Free tier is limited to 10 prompts per day, restrictive for regular use compared to some competitors.
  • Enterprise pricing is not published and requires contacting sales.
  • Primarily optimized for text-heavy images, which may not be the priority for purely photorealistic or artistic use cases.
