The short version

  • Only Caddy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Black Forest Labs open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.; Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • They diverge on capability: Black Forest Labs covers FLUX 3 image generation, Caddy covers Automatic HTTPS.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Black Forest Labs

  • Open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.
  • Video generation pricing per second can become costly for longer or higher-resolution outputs compared to subscription-based competitors.
  • No consumer subscription plan; pricing is oriented toward developers and enterprises rather than casual creators.

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
