The short version

  • Each has a real cost: OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • They diverge on capability: OpenTelemetry covers Vendor-neutral SDKs, 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.

OpenTelemetry

  • Genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • Language SDKs mature at different rates, so a polyglot estate gets uneven support
  • It produces and moves telemetry but does not store or visualise it, so a backend is still required and still billed

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

Questions people ask

Is OpenTelemetry or Trivy better?
Neither clearly leads. OpenTelemetry starts at Free and Trivy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, OpenTelemetry or Trivy?
OpenTelemetry starts at Free and Trivy at Free.
Does OpenTelemetry or Trivy run on more platforms?
OpenTelemetry runs on Linux, macOS, Windows, Kubernetes, Docker. Trivy runs on Linux, macOS, Windows, Docker, Kubernetes.
Can I use OpenTelemetry for free?
Both have a free tier, so you can try either at no cost before committing.
What is OpenTelemetry best used for?
OpenTelemetry is most often used for instrumenting once and keeping the option to change observability vendor later, standardising telemetry across services written in different languages, routing and filtering telemetry centrally to control observability spend. Of those, instrumenting once and keeping the option to change observability vendor later and standardising telemetry across services written in different languages are not what Trivy is typically brought in for.
What can OpenTelemetry do that Trivy cannot?
OpenTelemetry covers Vendor-neutral SDKs, Collector, Three signals, Auto-instrumentation. Trivy covers Multi-target scanning, Vulnerability detection, Misconfiguration checks, Secret detection.

Answered from the vendors’ own pages

OpenTelemetry: Is OpenTelemetry free?

Yes, open source under the CNCF. What you pay for is the backend you export to.

Trivy: Is Trivy free?

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

OpenTelemetry: Does OpenTelemetry replace Datadog or Grafana?

No. It replaces their proprietary agents and instrumentation libraries. You still need a backend to store and query the data.

Trivy: What can Trivy scan?

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

OpenTelemetry: Why adopt a vendor-neutral standard?

Because instrumentation is the expensive part. Once code emits OTel, changing observability vendor is a collector config change instead of re-instrumenting every service.

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.
