Containerd

Containerd is the industry-standard container runtime that powers Docker Desktop, Kubernetes, and virtually every major container platform in production today. As a graduated CNCF project, it handles over 75% of the world’s container workloads with exceptional reliability and performance.

What makes containerd essential is its position as the foundational layer for container execution - it provides the core functionality that higher-level platforms depend on. Built for minimal overhead and maximum stability, it’s designed to run billions of containers in production environments.

Platform engineers and DevOps teams rely on containerd because it delivers rock-solid container execution without the complexity of full container engines. From edge computing to massive Kubernetes clusters, it provides the reliable foundation that modern containerized infrastructure demands.
