The short version

  • Each has a real cost: Aikido free plan includes fair-usage limits on repos and container images; Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • They diverge on capability: Aikido covers Static Application Security Testing (SAST), Caddy covers Automatic HTTPS.

Where each one falls short

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

Aikido

  • Free plan includes fair-usage limits on repos and container images
  • Pricing increases significantly with user and repository scale
  • Advanced features like penetration testing and VM scanning limited to higher tiers
  • Device protection limited to Development environments only
  • Requires multiple plan tiers for full platform coverage

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
