K3s

K3s is the lightweight Kubernetes distribution developed by Rancher and adopted by thousands of organizations including SUSE, AWS, and edge computing leaders for resource-constrained environments. As a CNCF sandbox project, it has become the standard for running Kubernetes on edge devices, IoT deployments, and development environments with minimal overhead.

What makes K3s exceptional is its ability to deliver full Kubernetes functionality in a single 50MB binary that uses 90% less memory than standard Kubernetes. This dramatic resource reduction makes enterprise-grade container orchestration accessible on everything from Raspberry Pi devices to edge servers.

DevOps teams and edge computing specialists choose K3s because it provides production-ready Kubernetes without the complexity and resource requirements of traditional distributions. From IoT fleets to development laptops, it offers the Kubernetes power that modern applications need in any environment.
