What makes Kairos different?

swirl logo

Customizable to Your Needs

With Kairos, you're in the driver's seat. Build custom bootable-OS
images for your edge devices from your choice of OS and Kubernetes
distribution. These images are delivered as container images, and can
be customized and extended to your needs. Kairos fits neatly into
your CI/CD pipelines and lets you use the container engine of choice.

Consistent and Secure

Say goodbye to inconsistencies across your clusters as each node
boots from the same immutable image, ensuring uniformity. It also
reduces the risk of malicious attacks, and with data encryption, your
stored data remains protected, providing enhanced security for your
clusters.

to Install

We believe in making things simple. With Kairos, you can set up nodes
via QR code, manually, remotely via SSH, interactively or with
Kubernetes.

can be also done via Kubernetes. However - can also be used as a
standard Linux distribution. The configuration management is done via
