The short version

  • Each has a real cost: Podman native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect; Preact compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • They diverge on capability: Podman covers Daemonless architecture, Preact covers 3kB runtime.
  • 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.

Podman

  • Native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect
  • Docker Compose support arrives through a compatibility layer rather than natively, and complex Compose files can hit gaps
  • Rootless mode has real constraints around privileged ports and some storage drivers
  • Smaller ecosystem of tutorials and third-party integrations than Docker, so unusual problems have fewer existing answers

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Answered from the vendors’ own pages

Podman: Is Podman free?

Yes. Podman is open source with no licence fee, for personal or commercial use.

Preact: Is Preact free?

Yes, open source under the MIT licence.

Podman: Can Podman replace Docker?

For most everyday use, yes. The CLI is deliberately Docker-compatible and many teams alias docker to podman. Gaps appear mainly around Docker Compose and Docker Desktop-specific features.

Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Podman: What does daemonless actually mean?

Docker runs a central background service as root that owns every container. Podman does not: each container is a child process of the user who ran it, so containers can run without root privileges at all.

Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

Podman: Does Podman work on macOS?

Yes, but through a managed Linux virtual machine, because containers are a Linux kernel feature. That is the same approach Docker Desktop takes.
