The short version
- Each has a real cost: Buildah linux only, with no native macOS or Windows support; Zipkin less active development and smaller community momentum than Jaeger
- They diverge on capability: Buildah covers Daemonless builds, Zipkin covers Trace collection and search.
Where they differ
Only the attributes on which Buildah and Zipkin actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Cloud).

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
Zipkin
- Less active development and smaller community momentum than Jaeger
- Fewer features: sampling, storage options and UI are all more limited
- The interface is dated and slower to work with on large trace volumes
- Tracing alone still leaves metrics and logs in separate tools during an incident

Answered from the vendors’ own pages
Buildah: Is Buildah free?
Yes, open source with no licence fee.
Zipkin: Is Zipkin 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.
Zipkin: Zipkin or Jaeger?
Jaeger has more momentum, more features and CNCF backing. Zipkin is lighter and quicker to stand up, and remains well supported in the Java and Spring ecosystem.
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.
Zipkin: Does Zipkin work with OpenTelemetry?
Yes. OpenTelemetry can export to Zipkin, which is now the usual way to instrument for it.
