Caddy

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

Jasper

  • The Pro plan at $59 a month billed annually is a single user, and adding seats requires contacting sales
  • Pro is capped at 2 brand voices, 5 knowledge assets and 3 audiences
  • API access, custom agents and advanced admin controls are all Business only
  • The Business plan is custom priced and carries a minimum 12 month commitment
  • Several image tools including upscaling and background replacement are excluded from Pro
  • No word or credit allowance is published for either plan
