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

Play.ht

  • The vendor's own pricing FAQ as captured by the Internet Archive on 20 January 2022 states words do not roll over between subscription cycles and reset each renewal, that payments already made are non-refundable, and that running out of words requires a separate one-time purchase; no dollar figures appear in this capture but the mechanism is stated plainly by the vendor
