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

Tuta

  • Individual plan pricing only shown in EUR; no USD conversion provided on site
  • Family plan pricing separate (EUR 3 or EUR 8 per additional user) not included in main pricing
  • Shared mailboxes require additional EUR 3-8 monthly charges

Answered from the vendors’ own pages

Podman: Is Podman free?

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

Tuta: How much does Tuta email cost?

Tuta offers a free plan with 1 GB storage. Paid plans are EUR 3/month (Revolutionary) with 20 GB storage and 15 email aliases, and EUR 8/month (Legend) with 500 GB storage and 30 email aliases. Family plan add-ons cost EUR 3-8 per additional mailbox member monthly.

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.

Tuta: Is there a free email plan with Tuta?

Yes, Tuta's free plan includes 1 GB of storage, one calendar, three labels, and full end-to-end encryption security features with no custom domains or email aliases.

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.

Tuta: What are the limits on Tuta's free email plan?

The free plan provides 1 GB storage, access to one calendar, three labels maximum, and no support for custom domains or additional email aliases.

Source
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.
