Apple container vs Enroot

Apple container creates and runs Linux containers as lightweight virtual machines on a Mac. Written in Swift and optimized for Apple silicon, it gives each container its own lightweight virtual machine with core utilities and libraries. Host data is shared by mounting only the data needed inside each virtual machine. The tool consumes and produces OCI-compatible images that can be pulled from and pushed to standard registries. Documented features include CPU and memory limits, bind mounts, named volumes, tmpfs, DNS-based names, port forwarding, and isolated networks. It can run local single-node or multi-node Kubernetes clusters for development and testing, and documentation covers building, running, and publishing images for Apple silicon and x86-64. Integrations include macOS Virtualization, vmnet, XPC, launchd, Keychain services, and unified logging. Apple container is free, Apache-2.0 licensed, and supported on macOS 26, but requires Apple silicon. The project is under active development.

Enroot is a free, open-source Linux command-line utility that turns traditional container and operating-system images into unprivileged sandboxes. It is aimed at high-performance or virtualized environments where portability and reproducibility matter and additional isolation is not required. Enroot runs without a daemon and supports unprivileged multi-user use without a setuid binary. Linux user and mount namespaces preserve filesystem separation, while the project provides little to no isolation. The command line covers batch, bundle, create, exec, export, import, list, remove, and start operations. It imports known formats including Docker, with the README reporting a 3x to 5x speedup for large Docker-image imports. Built-in GPU support uses libnvidia-container, and hooks can add NVIDIA support or Mellanox host MOFED. Runtime settings come from enroot.conf or higher-priority environment variables. Standard and hardened package flavors are available.
