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

REST Client VSCode

  • Limited to Visual Studio Code; not available as a standalone application
  • No support for WebSocket, gRPC, or other advanced protocols
  • No cloud sync or team server features; requires Git-based workflow
