crun vs Docker Desktop

crun is a free, self-hosted OCI container runtime for Linux, written in C. It conforms to the OCI Container Runtime specifications and provides CLI operations for creating, running, executing commands in, listing, pausing, resuming, updating, checkpointing and restoring containers. It can generate a configuration for unprivileged use and creates a user namespace when run by a non-root user. The project documents integration with Podman, an Ansible role for installing a statically linked binary and a Lua binding. Build instructions cover Fedora, RHEL/CentOS Stream 9 and 10, Ubuntu, Alpine and openSUSE Tumbleweed; release binaries are listed for Linux amd64 and arm64, including variants without systemd. Official release artifacts are signed, with GPG verification commands provided. The project reports a benchmark of 100 sequential `/bin/true` containers completing in 1.69 seconds with crun versus 3.34 seconds with runc on the author's machine. The manual marks cgroup v1 support as deprecated. Regular patch releases target the latest version; fixes for earlier versions are best effort and not guaranteed.

Docker Desktop brings container development and deployment tools together for developers and teams. It includes Docker Engine, Docker CLI, Docker Compose, Docker Build, and Docker Kubernetes, with support for building images and Compose workflows. Its built-in Kubernetes environment lets users deploy, scale, test, and manage containerized applications locally without an external cluster. Docker Debug offers command-line diagnostics for containers and images, including slim containers, while Extensions allow third-party tools for debugging, testing, security, and networking. Downloads cover macOS with Apple Silicon or Intel, Windows with AMD64 or ARM64, and Linux; web is also listed as a platform. Docker Personal is free. Pro is $9 a month, Team is $15 a month, and Business is $24 a month. Paid-plan allowances and user limits differ. Business lists VDI support and additional security controls. Commercial use at companies with more than 250 employees or more than $10 million in annual revenue requires a paid subscription.
