The short version

  • Each has a real cost: HAProxy configuration syntax is dense and unforgiving, with a steep initial learning curve; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • They diverge on capability: HAProxy covers High throughput, Trivy covers Multi-target scanning.
  • Prices and features above were last checked on 29 August 2026.

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

Trivy

  • Reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • No built-in triage or exception workflow, so suppressing accepted risk is managed in config files
  • Findings are point-in-time from CI, with no continuous runtime monitoring unless you add the commercial platform

Answered from the vendors’ own pages

HAProxy: Is HAProxy free?

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

Trivy: Is Trivy free?

Yes, open source from Aqua Security with no licence fee. Aqua sells a commercial platform around it.

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.

Trivy: What can Trivy scan?

Container images, filesystems, Git repositories, Kubernetes clusters and infrastructure-as-code, for vulnerabilities, misconfigurations, secrets and licences.

HAProxy: Does HAProxy handle TLS certificates automatically?

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

Trivy: Does Trivy need a server?

No. It is a single binary, which is a large part of why it became a default in CI.
