K3s Has a Free API: Lightweight Kubernetes for Edge Computing

K3s is a lightweight, certified Kubernetes distribution designed for edge computing, IoT, and resource-constrained environments. Built by Rancher Labs (now SUSE), it packages the entire Kubernetes control plane into a single binary under 100MB. What Is K3s? K3s is a fully CNCF-certified Kubernetes distribution that strips away cloud-provider-specific code, alpha features, and non-essential plugins to create a minimal Kubernetes. It replaces etcd with SQLite by default, making it perfect for single-node clusters and edge deployments.
