I don't know a lot about containers. Would containers created for/with this also work in Docker?

Good name for this app, BTW.

It claims to be backed by (and require) apple/containers(1) which "consumes and produces OCI-compatible container images" so if all that is true .... yes!

1) https://github.com/apple/container

Why would someone downvote this perfectly relevant question?

Pathetic.
