Zero Friction

k0s drastically reduces the complexity of installing and running a fully conformant Kubernetes distribution. New kube clusters can be bootstrapped in minutes. Developer friction is reduced to zero, allowing anyone, with no special skills or expertise in Kubernetes to easily get started.

Zero Deps

k0s is distributed as a single binary with zero host OS dependencies besides the host OS kernel. It works with any operating system without additional software packages or configuration. Any security vulnerabilities or performance issues can be fixed directly in the k0s distribution.

Zero Cost

k0s is completely free for personal or commercial use, and it always will be. The source code is available on GitHub under Apache 2 license. It's a no brainer foundation for any Kubernetes projects and easy build upon.
