Where each one falls short

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

HAProxy

  • Configuration syntax is dense and unforgiving, with a steep initial learning curve
  • No automatic certificate management, unlike newer servers that treat it as default behaviour
  • The built-in stats page is basic, so real observability needs exporters and dashboards
  • A dedicated load balancer is more machinery than small deployments need

  • Pricing not published on main website or pricing page
