The short version

  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • They diverge on capability: Buildah covers Daemonless builds, 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.

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

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

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Trivy: Is Trivy free?

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

Buildah: Do I still need a Dockerfile?

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.

Trivy: What can Trivy scan?

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

Buildah: How is Buildah different from Podman?

Buildah builds images; Podman runs them. Podman actually embeds Buildah for its build command, and the two are designed to be used together.

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.
