The short version

  • Only Caddy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Koyeb pricing starts at $29/month with additional compute costs; Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • They diverge on capability: Koyeb covers Serverless containers, Caddy covers Automatic HTTPS.

Where each one falls short

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

Koyeb

  • Pricing starts at $29/month with additional compute costs
  • GPU compute is expensive at $0.75-$2.50 per hour
  • Limited customization for infrastructure configuration

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
