Kubernetes, an extensions marketplace, a build cloud, and somebody to call. Pick it when you need those, or want a vendor on the hook.
Cross-platform and ships Kubernetes. Pick it on macOS or Linux, or for a Kubernetes dev loop.
Daemonless and rootless. Pick it when a rootless, no-daemon model is the requirement.
Free of this project entirely. Pick it if you would rather wire dockerd into WSL2 and manage the pipe yourself.
