The Golang version, aka. Compose v2 can also be used standalone (they even have prebuilt binaries in their GitHub repository) and is compatible with Podman. Behind the scenes both Compose v1 and v2 use the Docker API which is also implemented by Podman (`podman system service`).
In my experience they work fine together most of the time, I have ran into compatibility bugs sometimes, though things seem to be steadily improving.
