  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

  • Requires reference to separate store page for tier details
  • AI credits needed for integrated AI features
  • No mention of free trial for commercial use
