podup runs your existing docker-compose.yml on rootless Podman. It speaks Podman's native libpod API, so there is no daemon, no Python and no root: one static Rust binary. It implements the Compose Specification (anchors, extends, include, profiles, env_file, variable substitution) with dependency-aware startup, healthchecks, replicas, secrets, configs and a watch mode. Any stack exports to systemd Quadlet units. Signed releases for Linux, macOS and Windows, from apt, Homebrew or Scoop.
