What makes Kairos different?

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 with our system's immutability as each node boots from the same image, ensuring uniformity. The system's immutability also reduces the risk of malicious attacks, and with data encryption, your stored data remains protected, providing enhanced security for your clusters.
