Where each one falls short

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

ProtonVPN

  • Free plan limited to one device at a time
  • Free plan restricted to 10 countries with random selection
  • Pricing amounts not clearly published; shown as variable

Answered from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

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.

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.
