I don't have any experience using podman in production. I use it on my dev PC for work, where I have to run Windows. Previously I used Docker Desktop for Windows, but I got tired of dealing with its various annoyances. Podman has been a mostly seamless drop-in replacement. It doesn't support swarm, which I used to use with docker, but I've found a good solution using docker-compose instead.

Not using it yet, but basically there where you cannot control who runs what, like shared builders or server with personal beyond infra/itsec teams may have access and need to be able to run containers. As being in group Docker/having access to Docker socket effectively means having root access, Podman/rootless docker can be a savior.
