Virtualizor and VirtFusion alternatives: what to compare before you switch
Looking for a Virtualizor or VirtFusion alternative? Compare the move itself, price per node, billing, security and GPUs, and what VorticPanel doesn't do.
5 min read
Most hosts who look for a Virtualizor or VirtFusion alternative aren't unhappy with KVM. They want a lower bill per node, a panel that does more of the routine work itself, a second product such as GPU servers, or all three. The hard part isn't finding another panel. It's moving a running fleet without a week of tickets.
This post is the list we'd compare panels on, with how VorticPanel answers each one, including what it doesn't do. For the click-by-click migration, see Migrating from Virtualizor or VirtFusion.
The move comes first
A new panel is only worth it if getting your servers into it is safe. Ask any alternative how it brings servers across, what they keep, and how you undo it.
VorticPanel reads the old panel through its API and offers two ways per hypervisor, mixed freely in one import:
- Copy moves a server to one of your VorticPanel nodes while it keeps running. The node copies the disk, sends what changed again, then shuts the server down only for a last short pass. In our own test import from Virtualizor, a 1.8 GB disk came across in 14 seconds while the server ran, and the last pass had nothing left to send.
- Adopt leaves the server on its hardware. Install the agent on the old hypervisor, enroll it as a node, and each server restarts once under VorticPanel.
What a server keeps: its CPU, memory and disk (even when the package it's mapped to is smaller), its IP addresses and reverse DNS, MAC address, power state (one that was off stays off), suspension, extra disks, traffic used this month and its own traffic limit, port speeds, and its BIOS or UEFI boot with NVRAM. Windows servers keep their chipset, disk bus, network card and Hyper-V settings, so they boot with the drivers they have. Owners get an account with their name, company and saved SSH keys, and a "Your server has moved" email with a link to set their password. Virtualizor cloud users' customers can come over as customers of one of your resellers.
Before anything moves, a dry run checks every server from the node that will move it and estimates its downtime. After it moves, every server can be rolled back on its own for 3, 7 or 14 days. On the billing side, the WHMCS module's switch tool and the Blesta module's Manage page move each billing service over to the server it became.
The details for each panel are on moving from Virtualizor and moving from VirtFusion, and in the import guide.
Price per node
All three price per node, so the bill grows with your fleet. List prices per node per month, as on our pricing page in October 2026:
| Panel | Per node, per month |
|---|---|
| Virtualizor Premium | $9 |
| Virtualizor Professional | $18 |
| VirtFusion | $18 |
| VorticPanel Unlimited (unlimited VMs) | $7 |
| VorticPanel Standard (up to 5 VMs) | $4 |
| VorticPanel Single (1 VM) | $1 |
Check the other panels' current prices before you decide. The smaller VorticPanel plans suit nodes that run a few large servers or one dedicated customer, where a full per-node license costs more than it earns.
Moving servers between your own nodes
Once you're switched, you'll move servers for maintenance, upgrades and rebalancing far more often than you'll ever import. Compare what a move costs your customers.
VorticPanel moves a running server live when both nodes' CPUs allow it. When they don't, such as between Intel and AMD nodes, it moves with a restart: the disk is copied while the server runs and every write goes to both copies, so it's off only for a clean shutdown and a start. In our own moves from an AMD node to an Intel one and back, the server was off for 9 and 11 seconds.
Move them off empties a whole node for maintenance, places each server, and gives new addresses to servers whose own won't work on their new node, setting them inside the server and emailing the owner. See Live-migrating KVM servers between nodes.
Billing panels and the API
Your billing panel owns the money, so the panel has to be easy to drive. VorticPanel has modules for WHMCS and Blesta, with one-click sign-in for clients. Every action staff can take is also an API call with permission scopes, and calls that create or change something take an idempotency key, so a billing retry after a timeout never makes a second server. Panel API keys belong to the panel rather than a person, so billing keeps working when staff leave. Webhooks report what happens to servers, backups, moves, GPU instances and nodes, and can post straight to Slack, Discord or Telegram.
Security you can check
A VPS panel has root on every node, so ask how it protects that.
- Every release and every node agent is signed, and panels and nodes only install what's signed.
- Nodes connect out to the panel and need no management port open. Each node pins the panel's key and ignores anything that can't prove it.
- Private networks between servers on different nodes go through WireGuard.
- Backups are encrypted on the node before they leave it, with a key per server, to S3-compatible storage or SFTP.
- A lapsed license locks the staff area only. Customers' servers, consoles and pages keep working.
Why the panel never needs a way in to your KVM hypervisors and the security page go into more detail.
A second product: GPUs
VorticPanel sells GPUs two ways. Cards of any make can be passed through whole to KVM servers. NVIDIA cards can also be rented out by the hour as containers on a GPU container host, with JupyterLab over HTTPS, customers' own Docker images where you allow them, and usage that WHMCS bills by the hour. See Selling GPU servers by the hour with WHMCS.
What VorticPanel doesn't do
- It runs KVM only. OpenVZ and LXC containers can't move to it and stay on the old panel.
- It's software you run yourself: one command installs the controller on Debian or Ubuntu, and you keep its encrypted backups.
- Billing stays in your billing panel. VorticPanel has no prices, credit or ordering of its own.
Trying it
The 15-day trial covers up to three nodes, with no card needed. A good test is to import one disposable server from your current panel, check it, then roll it back, which starts the original again where it was. Your other servers stay where they are until you choose to move them. Start the trial, or read the import guide first.
