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

Porter

  • Pricing based on vCPU and memory can be expensive for small projects
  • Vendor lock-in to Porter platform despite multi-cloud support
  • Limited customization for complex infrastructure requirements

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.

Porter: Does Porter include cloud provider costs?

Porter pricing excludes underlying cloud provider costs (AWS, Azure, GCP), though cloud credits can offset those expenses.

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

Porter: Do startups get special pricing?
