What's Good
Apache-2.0. containers/buildah (Podman tooling family). Builds from Dockerfile/Containerfile or scripted `buildah from`/`run`/`commit` — daemonless, rootless-friendly, mounts cleanly into Podman workflows. Docs at buildah.io; source github.com/containers/buildah.
The Catch
Vs Docker (encyclopedia — engine+Desktop), Podman (*run* containers/pods), ko (*Go-only* no-Dockerfile), and Hadolint (Dockerfile *linter*): Buildah is the *image builder*, not the runtime and not the linter. Learning curve if you leave Dockerfile mode for the scripted API.
Verdict
Apache-2.0 rootless image builds. Free forever; Podman runs what Buildah builds.
