| Provisioning | Metal³ can discover hardware, configure BIOS and RAID, clean disks, install operating system images, deploy Kubernetes, and perform rolling upgrades. | xCAT provisions operating systems on physical or virtual machines using diskful, stateless, or cloned installation methods. |
| Purpose | Metal³ is an open-source project that provides tools for managing bare-metal infrastructure using Kubernetes. | xCAT automates deployment, scaling, and management of bare metal servers and virtual machines. |
| Security | The project directs suspected vulnerability reports to its security mailing list and documents severity assessment, fixes, and disclosure handling. | The security documentation covers TLS configuration, transmission channels, command access control, auditing, password management, secure zones, and IP-based access control. |
