HADRON by Kairos

The foundation for image-based systems.

Hadron is a minimal, upstream-aligned Linux distribution built from scratch with musl, systemd, vanilla kernels and no package manager — designed for predictable cloud and edge environments.

Topped with Kairos, it becomes immutable and has powerful lifecycle management. It's the foundation for image-based systems.

Engineered by the Kairos team at Spectro Cloud.
