Where each one falls short

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

Carrd

  • Free tier strictly limited to 3 sites; any additional sites require upgrading to Pro
  • Pro plan includes Carrd branding removal but still lacks advanced features (e-commerce, multi-step funnels, complex forms)
  • Single-page design only; does not support multi-page websites or complex site structures
  • Limited template library compared to competitors like Leadpages or Unbounce
  • Annual payment required for Pro tier; no monthly payment option
  • No native A/B testing, analytics dashboard or conversion optimisation tools built-in

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

Answered from the vendors’ own pages

HAProxy: Is HAProxy free?

Yes, the community version is open source. HAProxy Technologies sells HAProxy Enterprise separately.

Carrd: Can I use Carrd for e-commerce?

Carrd's Pro plan supports payment forms with Stripe integration, but it is not a full e-commerce platform. Single-product sales or payment collection is possible, but inventory management and complex product catalogs are not supported.

Source
HAProxy: HAProxy or Nginx?

HAProxy is a specialist load balancer with deeper balancing and health-check features. Nginx also serves static content and is more approachable, which is why it is more common as a general web server.

Carrd: Can I create multi-page websites with Carrd?

No. Carrd is designed for single-page sites only. For multi-page websites, you would need to use a full website builder like Webflow or Squarespace.

HAProxy: Does HAProxy handle TLS certificates automatically?

No. Certificate issuance and renewal are external, unlike Caddy where it is automatic.
