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

Pants Build

  • Smaller community compared to Bazel with fewer third-party tool integrations
  • Python plugin API steeper learning curve for custom build rules
  • Less mature ecosystem for non-Python languages
  • Fewer integration examples for enterprise CI/CD platforms

Answered from the vendors’ own pages

Yes, open source with no licence fee.

Pants Build: What languages does Pants support?

Pants supports Python as a first-class citizen, with production-ready support for Go, Java, Scala, Kotlin, Shell scripts, and Docker.

Source
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.

Pants Build: Do I need to write BUILD files with Pants?

Pants uses static analysis to infer dependencies and project structure, minimizing required BUILD file configuration compared to other build systems.

Source
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.

Pants Build: How does Pants handle complex dependency scenarios?

Pants provides file-level dependency tracking, multiple dependency resolves with lockfiles, and sophisticated dependency analysis that works correctly even with circular or complex dependency graphs.
