The short version

  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; Memcached no persistence at all: restart a node and its cache is gone, which every design must assume
  • They diverge on capability: Buildah covers Daemonless builds, Memcached covers In-memory key-value cache.
  • Prices and features above were last checked on 1 September 2026.

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

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Answered from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Memcached: Is Memcached 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.

Memcached: Memcached or Redis?

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

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.

Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.
