Apple container vs youki

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.

youki is a Linux container runtime written in Rust that implements the OCI runtime specification. It provides commands to create, start, list, inspect, and delete containers, and can run containers without root privileges. The project documents using it as a runtime with Docker and Podman, and reports passing containerd’s end-to-end test and adoption in several production environments. Building locally requires Rust edition 2024 and Linux kernel 5.3 or later; local builds are supported on Linux, with Vagrant environments and GitHub Codespaces available for trying it elsewhere. The project is a Cloud Native Computing Foundation sandbox project. youki is free under the Apache License, Version 2.0, which grants no-charge, royalty-free copyright and patent licenses subject to its terms.
