> It may allow for other container backends in the future, but currently it's only docker ([nektos/act#303](https://github.com/nektos/act/issues/303))

It allows for other container backends already, it just needs to have Docker Engine compatible API and connection option, e.g. `DOCKER_HOST=unix:///var/run/podman.sock`
