Podman is a container engine designed for managing containerized applications and images without the need for a persistent background daemon. By utilizing a fork-exec process model, it executes container management commands as direct child processes of the host system, ensuring that container lifecycles are handled through standard host-level process control. The project distinguishes itself through a focus on rootless security and cross-platform compatibility. It employs user namespace mapping to allow unprivileged users to manage isolated workloads without requiring administrative system ac

Youki is a low-level container runtime written in Rust that creates and manages isolated containers according to Open Container Initiative specifications. It serves as an execution engine that can function as a rootless container manager or a pluggable Kubernetes CRI runtime to manage pods and containers within a cluster. The project distinguishes itself by providing a Wasm container runtime capable of executing WebAssembly modules as isolated workloads compatible with standard orchestration tools. It further supports a rootless execution model, allowing isolated environments to start as non-

Moby is an OCI container engine and runtime manager designed for building, running, and managing isolated containers based on Open Container Initiative standards. It functions as a container daemon and image builder, providing a core engine to orchestrate the full lifecycle of containers and the packaging of source code into portable images. The project provides a standardized HTTP interface that allows for programmatic container management, enabling external clients to control daemon settings and container operations. It supports a rootless security model, allowing the engine daemon to execu

rkt is a secure Linux container engine and pod-native container manager. It provides a composable execution environment for launching and managing isolated application containers on Linux, serving as a runtime designed around open industry standards for image formats and networking interfaces. The system is distinguished by a pod-native execution model that groups multiple containers and shared resources into single, self-contained units. It utilizes pluggable execution engines to provide secure isolation, including the use of hardware-based virtualization to create security boundaries betwee

Libpod is a container management library for running and controlling the lifecycle of Open Container Initiative compliant containers and images across different storage backends. It provides a programmatic interface for the remote control and automation of container environments. The project enables the coordination of multiple containers into pods that share network namespaces and other shared resources. It supports rootless container execution by using user namespaces to launch containers without administrative privileges. The library covers a broad range of system operations, including im

rkt is a pod-native container engine and runtime for Linux that executes containerized applications as isolated pods. It serves as an OCI container runtime and a Linux container manager, supporting the execution of images based on Open Container Initiative, appc, and Docker specifications. The project distinguishes itself by offering hardware-level container isolation, allowing pods to run within virtual machines using KVM or QEMU for a dedicated kernel. It further separates itself through secure container deployment practices, utilizing SELinux mandatory access control and TPM-backed integri

Kata Containers is an OCI container runtime that launches containers inside lightweight virtual machines to combine hardware-level isolation with container operational speed. It functions as a hardware-isolated container engine and lightweight VM hypervisor, providing a virtual machine monitor interface that abstracts multiple hypervisors to optimize for performance or specific hardware emulation. The project distinguishes itself through a confidential computing runtime that leverages hardware-backed trusted execution environments, such as Intel TDX and AMD SEV-SNP, to protect data in use. It
