CST VerdictBased on our analysis of available product data, here is our conclusion:
Infrastructure teams managing distributed storage or virtualization environments over untrusted networks should evaluate nbdserver for its lightweight, protocol-compliant approach to remote block device access without the overhead of heavier solutions. At 515 GitHub stars with active maintenance, it demonstrates real adoption in production labs and edge deployments where simplicity and auditability matter more than vendor support. Skip this if you need commercial SLAs, formal security audits, or integration with enterprise storage management platforms; nbdserver is a specialized tool for teams comfortable owning their own deployment and security hardening.
DevOps teams building container images in air-gapped or daemon-constrained environments need Buildah because it eliminates the Docker daemon dependency that creates both operational friction and a persistent privileged process. With 8,671 GitHub stars and adoption across Red Hat's ecosystem, it's proven at scale for rootless builds and OCI compliance. Skip this if your team is standardized on Docker Desktop and wants a single tool for both image building and local testing; Buildah excels at the build step but won't replace your container runtime.
