The foundational Linux distribution for the cloud and the edge.
Hadron delivers a minimal, trustworthy operating system built from the ground up with vanilla upstream components. Engineered for security, flexibility, and reliability.
Hadron is Engineered by Spectro Cloud from the Kairos team.
- Minimal & Lean: Bare essentials only—no bloat, just what you need
- Trusted Boot: Secure boot environments with modern security standards
- Upstream First: Built with vanilla components, staying close to upstream
- Edge & Cloud Ready: Optimized for both cloud workloads and edge deployments
- Seamless Updates: A/B upgrade capabilities for zero-downtime operations
Hadron is a Linux Distribution built from scratch with a focus on minimalism and staying close to upstream sources:
- Core Components: Built on
musllibc,systemdinit system, and vanilla Linux kernels - Boot Methods: Supports both Trusted Boot (via USI/UKI) and standard boot (via Dracut/GRUB)
- Upgrade System: Managed via Kairos agent for A/B style atomic upgrades
- Upstream Alignment: Minimal patches, maximum compatibility with upstream projects
- Simple and no vendor-lock-in: Hadron doesn't ship a package manager by default, and it's not based on any other Linux distribution. You can build packages on top of Hadron, or use the package manager you like.
To build locally the image, you just need to have Docker installed, clone the repository and run:
make build
To create an ISO, you can:
make devel-iso
And you can run it in a VM with:
make run-qemu
Apache 2.0
