Proxmox VE vs Virtualizor

Proxmox VE is an open-source, self-hosted server virtualization platform that manages KVM virtual machines and Linux Containers from an integrated web interface. A bare-metal installation includes a 64-bit Debian GNU/Linux operating system with a Proxmox kernel; installation uses the selected server and removes existing data on selected disks. Administrators can also manage the system through a command-line interface and REST API. The cluster stack supports multi-node management from any node, with high availability monitoring and automatic action when a VM or container fails. Running VMs can migrate between cluster nodes without noticeable end-user downtime. Storage options include NFS, SMB/CIFS, iSCSI, Ceph, GlusterFS, LVM, ZFS and directory storage. Proxmox Backup Server integration provides incremental encrypted backups, live restore and single-file recovery. The software is free to download under GNU AGPLv3. Paid subscriptions are per occupied physical CPU socket; each cluster server needs coverage at the same subscription level. The maker is Proxmox Server Solutions GmbH, founded in 2005 and headquartered in Vienna, Austria.

Virtualizor is a self-hosted, web-based control panel for hosting providers running VPS and cloud infrastructure. It connects operators, customers, and hypervisors on server nodes, with API access for provisioning and management workflows. Supported hypervisors include OpenVZ, OpenVZ 7, Xen PV, Xen HVM, XenServer, Linux KVM, LXC, Proxmox, and Virtuozzo; Docker and bare-metal management are also described. Administrators can create, start, stop, rebuild, clone, and migrate virtual machines. Browser-accessible noVNC and VNC consoles are provided, alongside RDP and serial console access. Templates cover Linux, Windows, and Webuzo systems. Integrations include WHMCS, Blesta, HostBill, and ClientExec modules, plus PHP and Python SDKs. Security controls include login limits, bans, LDAP, two-factor authentication, and IP allowlists. Backuply adds scheduled incremental backups, remote uploads, rotation, and restores.
