The short version

  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; Docusaurus customisation past the config file assumes React knowledge, which not every docs team has
  • They diverge on capability: Buildah covers Daemonless builds, Docusaurus covers MDX authoring.
  • Prices and features above were last checked on 29 August 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

Docusaurus

  • Customisation past the config file assumes React knowledge, which not every docs team has
  • Build times grow noticeably on very large sites, particularly with many versions and locales
  • Major version upgrades have required real migration work rather than a dependency bump
  • It generates a static site, so anything dynamic — gated content, per-user docs — needs a separate solution

Answered from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Docusaurus: Is Docusaurus free?

Yes. Docusaurus is open source from Meta with no licence fee. You pay only for hosting, and static output can be served from free tiers on Netlify, Vercel or GitHub Pages.

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.

Docusaurus: What is Docusaurus built with?

React and MDX. Pages are authored in MDX — Markdown that can embed React components — and the theme layer is React, so layouts are extended with components.

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.

Docusaurus: Does Docusaurus support multiple documentation versions?

Yes. Versioning is built in, so documentation for several released product versions can be maintained side by side, which is a main reason projects choose it.

Docusaurus: Does Docusaurus include search?

It integrates with Algolia DocSearch rather than shipping its own search index. Open-source projects can typically use Algolia’s free DocSearch programme.
