| Intended users | The project describes Cobbler as suitable for small and large installations and says it is used by companies, universities and government organizations. | The documentation recommends installing Confluent directly for most users, especially those without an existing xCAT installation, while users relying on xCAT-exclusive features can run both together. |
| Interfaces | Cobbler provides a command line interface, a WebUI and Python and XML-RPC APIs. | Users can operate Confluent through Linux commands, the confetty command-line browser, a Python client library, or a REST API over HTTP. |
| Purpose | Cobbler is a Linux installation server for setting up and automating network installation environments. | Confluent handles server-cluster bootstrap and day-to-day operations, including OS deployment, hardware control, console management, telemetry, and device onboarding. |
| Security | The security policy says Cobbler has no SELinux or AppArmor profile and advises protecting it because it manages DHCP and TFTP and has broad network control. | The documentation describes validated TLS for collective, deployment, and hardware-management traffic, TPM2 support for boot-volume protection and persistent node trust, SSH PKI, and Secure Boot support for media and HTTP boot. |

In their own words
Cobbler
Cobbler is free, self-hosted Linux server software for creating and automating network installation environments. It supports PXE deployments, virtualization with Xen, QEMU/KVM, or VMware, and reinstallation of existing Linux systems. Administrators can coordinate DNS, DHCP, package updates, power management, and configuration-management orchestration. Interfaces include a command line, WebUI, and Python and XML-RPC APIs. Automated installation formats include AutoYaST for SUSE and openSUSE, Kickstart, and Preseed for Debian and Ubuntu. Templates and reusable snippets generate installation files and manage services such as DNS and DHCP. Cobbler integrates with cfengine3, Puppet, bcfg2, and Chef, or its internal lightweight system. It can be installed from distribution packages or source; pip installation is documented but not recommended. Python 3 is required, and server setup needs Apache, certificate, and administration knowledge. Security guidance notes broad network control and no SELinux or AppArmor profile. The project describes use in small and large installations.
