| Hardware limits | Only Ironic is currently supported as a provisioner, and the FAQ says support for other provisioners is not on the roadmap. | NVIDIA says its Hardware Compatibility List identifies hardware currently supported from NICo's perspective and is not an exhaustive platform certification or qualification. |
| Purpose | Metal³ is an open-source project that provides tools for managing bare-metal infrastructure using Kubernetes. | NICo is an open-source suite of microservices for site-local, zero-trust bare-metal lifecycle management aimed at NVIDIA Cloud Partners and infrastructure operators. |
| Security | The project directs suspected vulnerability reports to its security mailing list and documents severity assessment, fixes, and disclosure handling. | The site controller's services communicate over mTLS/gRPC, and its operator debug web UI uses HTTPS with OIDC authentication. |
