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; Terragrunt additional complexity layer on top of Terraform
  • They diverge on capability: Podman covers Daemonless architecture, Terragrunt covers Infrastructure orchestration.

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

Terragrunt

  • Additional complexity layer on top of Terraform
  • Requires understanding of Terraform concepts
  • Paid tier pricing not clearly published

Answered from the vendors’ own pages

Podman: Is Podman free?

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

Terragrunt: Is Terragrunt free?

Yes, the Terragrunt CLI is completely free and open source. Terragrunt Scale offers a free tier for up to 25 infrastructure units.

Source
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.

Terragrunt: What is the difference between Terragrunt and Terraform?

Terragrunt is an orchestration layer on top of Terraform that handles state management, DRY principles, and deployment automation without replacing Terraform itself.

Source
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.

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.
