Proxmox vs VMware used to be a features argument. Since VMware stopped selling perpetual licenses in December 2023, it’s a pricing one: a small cluster’s VMware renewal now costs several times a Proxmox subscription for the same hosts. For shops with two to fifty hosts, Proxmox is the better buy: it covers HA, live migration, snapshots, backups and hyper-converged storage, which is what those shops use day to day. Stay on VMware only if you depend on NSX, Fault Tolerance, stretched vSAN or an ISV stack certified only on vSphere.
Here’s what Broadcom changed. Everything is a subscription now, sold mainly as two bundles, vSphere Foundation (VVF) and VMware Cloud Foundation (VCF). You pay per physical core, with a floor of 16 cores per CPU (Broadcom KB 313548), so an 8-core CPU is billed as 16. A 72-core minimum per order was announced in early 2025. Reports disagree on whether it still applies, and at least one Broadcom partner still quotes it. Either way, it wouldn’t change the bill for the 192-core cluster below. Cloud partners got hit hardest: the provider program went invite-only, and Broadcom told the partners it didn’t invite that their contracts wouldn’t be renewed after 26 January 2026.
What you pay: one 3-node cluster, two bills
Take a common starting point. Three hosts, two sockets each, 32 cores per socket. That’s 6 sockets and 192 cores, and the 16-core floor doesn’t bite because every CPU is over it.
One catch before the numbers. Broadcom doesn’t publish a price list, so the VMware figures below are reported list and quoted prices from two third parties: AceMQ’s renewal research, which covers 37 quotes AceMQ, itself a Broadcom partner, issued or reviewed between September 2025 and September 2026, and Redress Compliance, which puts VCF list at $350 to $400 per core per year. Your quote will be different.
Proxmox does publish its prices. They’re per CPU socket, per year, in euros, net of VAT. Core count doesn’t change them, every tier gets every feature, and all nodes in a cluster have to sit on the same tier.
| Product | Unit | List or quoted price | Annual for this cluster | Source note |
|---|---|---|---|---|
| VMware VVF | per core / year | ~$138 reported list | 192 × $138 = ~$26,496 | AceMQ, reported list |
| VMware VVF | per core / year | $119–126 quoted | 192 × $119 to 192 × $126 = $22,848–$24,192 | AceMQ, recent quotes |
| VMware VCF | per core / year | ~$344 reported list ($350–400 per Redress) | 192 × $344 = ~$66,048 ($67,200–$76,800 on the Redress range) | AceMQ; Redress Compliance |
| Proxmox VE Community | per socket / year | €120 | 6 × €120 = €720 (roughly $820) | proxmox.com; enterprise repo, no tickets |
| Proxmox VE Basic | per socket / year | €370 | 6 × €370 = €2,220 (roughly $2,530) | proxmox.com; 3 tickets, 1 business day |
| Proxmox VE Standard | per socket / year | €550 | 6 × €550 = €3,300 (roughly $3,750) | proxmox.com; 10 tickets, 4 h on critical |
| Proxmox VE Premium | per socket / year | €1,100 | 6 × €1,100 = €6,600 (roughly $7,510) | proxmox.com; unlimited tickets, 2 h on critical |
| + Proxmox Backup Server Standard (optional) | per server / year | €2,240 | 1 × €2,240 = €2,240 (roughly $2,550) | proxmox.com |
Dollar figures for Proxmox are rough conversions at the ECB reference rate of $1.1378 per euro on 28 September 2026.
VMware subscriptions come with Broadcom support, so the fair comparison is Proxmox Standard or Premium, not Community. Put the top Proxmox tier plus a backup server subscription next to VMware’s cheaper bundle: about €8,840, roughly $10,000, against about $26,500 at reported list. At Standard without the backup subscription it’s about a seventh of VVF, and about a quarter with it. Against VCF, even Premium plus backups is less than a sixth.
Negotiation narrows that. Redress says negotiated VCF deals often land 30 to 55% below list, and even 55% off AceMQ’s reported $344 list leaves VCF at about $30,000 a year on this cluster.
And the Proxmox column is optional. Proxmox VE is licensed under the AGPLv3; you can run it with no subscription and pay for nothing but hardware.
Features side by side
Short version: Proxmox has a real answer for most of what a small or mid-size cluster does every day. It has no answer for two VMware features and only a partial one for several more.
| VMware feature | Proxmox equivalent | Parity | Note |
|---|---|---|---|
| vMotion | Live migration | Full | Works on shared storage, or with local disks copied during the move |
| Storage vMotion | Live disk move | Full | Moves a running VM’s disk between storage pools |
| HA | HA manager with watchdog fencing | Full | Needs 3 nodes for quorum, or 2 plus a QDevice |
| DRS | Cluster Resource Scheduler (CRS) | Partial | Dynamic load balancing since PVE 9.2 (May 2026); only balances HA-managed guests |
| vSAN | Ceph, built into the installer and GUI | Partial | 3+ nodes; 3 copies by default, so usable space is about a third of raw; more hands-on |
| NSX | None | None | SDN covers VLAN, QinQ, VXLAN and EVPN/BGP zones plus a per-VM firewall; no NSX-style policy engine |
| Fault Tolerance | None | None | HA restarts a failed VM on another node; nothing runs a lockstep copy |
| vCenter | Cluster GUI on every node; Proxmox Datacenter Manager for many clusters | Partial | No separate appliance for a single cluster |
| Snapshots | Snapshots | Partial | Fine on ZFS, Ceph, LVM-thin and qcow2; none on shared thick LVM (typical FC/iSCSI SAN) outside a tech preview |
| Backup (VADP ecosystem) | Proxmox Backup Server; Veeam plug-in | Partial | PBS deduplicates; fewer third-party tools than VADP |
| Containers | LXC, native | Partial | System containers next to VMs; no bundled Kubernetes service like VCF’s |
| API / IaC | REST API; community Terraform provider | Partial | The GUI runs on the same API; PowerCLI scripts need rewriting |
| License model | Optional per-socket subscription | n/a | VMware: per core, 16-core floor. Proxmox: per socket, cores ignored |
The DRS row is the one most comparisons get wrong. Plenty of 2025 write-ups say Proxmox has no DRS. That stopped being true with Proxmox VE 9.2, which added a dynamic mode to CRS that uses live node and guest load to migrate HA-managed guests. It’s narrower than DRS, but it’s there.
Ceph is the other row that needs a caveat. It’s a good vSAN replacement on three or more nodes, but you own the tuning and the network design, and nothing hides that from you.
Where VMware still wins
NSX is the big one. If your security model is built on micro-segmentation policies that follow a VM around, Proxmox SDN and its firewall won’t give you that without a lot of work.
Fault Tolerance has no equivalent. Neither does the certified ecosystem: Site Recovery Manager runbooks, hardware compatibility lists, and ISV support matrices that list vSphere but not Proxmox, which matters if a vendor such as SAP ties support to a certified hypervisor. Stretched vSAN across two sites with a witness is also hard to copy. Ceph has a stretch mode, but Proxmox won’t set it up for you, and you’d be designing and testing it yourself. Multi-tenant self-service is thin too. Proxmox gives you pools and permissions, not a tenant portal; we built our own for our cloud.
Need two of these? Stay, and negotiate hard.
Where Proxmox wins beyond price
There’s no per-core math and no bundle of products you’ll never deploy. The code is AGPLv3 and the subscription optional, so there’s no core count for an auditor to check. It runs on Debian. ZFS and Ceph come in the box, and the backup server is a free separate install. The REST API and the community bpg/proxmox Terraform provider cover automation, and LXC containers run next to VMs on the same host.
Support and skills
Proxmox support is sold by the socket, same as the subscription. The cheapest tier with tickets, Basic, gives you 3 a year and a one-business-day response. Standard raises that to 10 tickets and 4 hours on critical issues, while Premium is unlimited with 2 hours on critical. Proxmox says Premium goes 24/7 on 19 October 2026 and Standard follows by the end of 2026.
The skills gap is smaller than it looks. The ramp is Linux, KVM, ZFS and Ceph, not a new proprietary language, and the thing that actually takes time is rewriting whatever you’d built on PowerCLI.
If you’d like a second pair of hands on the box, our managed servers plan is $99/mo with a 99.95% SLA and 15-minute response; ask us what it covers on a Proxmox host.
Performance
On the same hardware, the hypervisor is rarely what you’ll feel. What you’ll feel is a Windows guest still on emulated SATA and e1000 after the move, or Ceph squeezed onto a 1 Gbps network. VirtIO drivers fix the first (our migration guide walks through it). Storage design fixes the second.
Who should switch
Small hosting or SaaS shop: switch. The bill is the whole argument.
Mid-size IT team with a renewal in the next year: switch, but give it a quarter. Pilot on a spare cluster, move stateless workloads first and databases last, and keep the ESXi copies powered off but intact until you trust the new side.
If you’re an enterprise that runs on NSX and SRM, stay put and negotiate. Look again when the next renewal comes around.
We’ve run our own VPS and cloud platform on Proxmox for over 15 years, and Proxmox comes preinstalled on our Proxmox dedicated servers at no extra charge. We help with the move. On larger deployments it’s often included; smaller jobs are quoted up front.
FAQ
Yes. Proxmox VE is licensed under the AGPLv3 and every feature works without a subscription. The paid tiers, from €120 to €1,100 per socket per year, buy access to the enterprise repository and, above Community, support tickets.
Yes. GigeNET’s own VPS and cloud platform has run on it for over 15 years. The real requirement is someone on the team who understands clustering and, if you use it, Ceph.
Close to it, since Proxmox VE 9.2 in May 2026. The Cluster Resource Scheduler’s dynamic mode migrates HA-managed guests based on live load. It’s narrower than DRS, and comparisons that say Proxmox has no load balancing are out of date.
For most clusters of three or more nodes, yes. With the default of three copies, plan on usable space of about a third of raw. There’s no clean equivalent of a stretched two-site vSAN cluster.
Sort of. Broadcom re-released ESXi 8.0 Update 3e as a free hypervisor in April 2025, limited to 2 physical CPUs per host and 8 vCPUs per VM, with no vCenter management and no Broadcom support. Broadcom positions it for home labs and dev/test, not production clusters.
