Since Broadcom’s acquisition of VMware, licensing costs have multiplied for many organizations. Perpetual licenses have been abolished, forced bundle packages introduced, and existing contracts terminated. Many businesses are looking for alternatives — and finding them in Proxmox VE.
As a Proxmox Authorized Reseller, we have already guided numerous organizations through the migration from VMware to Proxmox. Here is an honest comparison of both platforms.
Feature Comparison: Proxmox VE vs VMware vSphere
| Criterion | Proxmox VE | VMware vSphere |
|---|---|---|
| License Cost (per socket/year) | Free (Subscription from ~100 EUR) | From approx. 4,500 EUR (vSphere Foundation) |
| License Model | Open Source (AGPL v3) | Proprietary, subscription only |
| Hypervisor | KVM (Linux) | ESXi (proprietary) |
| Containers | LXC (integrated) | Not native (only via Kubernetes/Tanzu) |
| Live Migration | Yes, possible without shared storage | Yes (vMotion), shared storage required |
| HA Cluster | Integrated (from 3 nodes) | vSphere HA (additional license) |
| Storage Replication | Integrated | vSphere Replication (separate license) |
| Software-Defined Storage | Ceph (integrated) | vSAN (separate license) |
| Backup | PBS (open source) | Veeam or similar (paid) |
| Web Interface | Fully featured (no additional software) | vSphere Client + vCenter required |
| API | Full REST API | vSphere API (complex) |
| Windows Support | Full (KVM + VirtIO) | Full (VMware Tools) |
| GPU Passthrough | Yes | Yes |
| Vendor Lock-in | None (open source) | Strong (proprietary format) |
Cost Comparison: 3-Node Cluster
A realistic example: 3 servers with 2 CPU sockets each, HA cluster with shared storage.

Frequently Asked Questions
Is Proxmox a real alternative to VMware?
Yes, Proxmox VE is the leading open-source alternative to VMware vSphere. It offers KVM full virtualization, LXC containers, HA clusters, live migration, and storage replication — comparable enterprise features without licensing costs.
How much does VMware cost compared to Proxmox?
Since the Broadcom acquisition, VMware vSphere costs from approximately 4,500 EUR per CPU socket per year (vSphere Foundation). Proxmox VE is free to use. The optional Enterprise Subscription costs from approximately 100 EUR per year per CPU socket — over 95% cheaper.
Can you migrate VMs from VMware to Proxmox?
Yes, migration is possible via OVF export, disk conversion (qemu-img), or specialized migration tools. DATAZONE professionally guides the migration with minimal downtime.
Why are businesses switching from VMware to Proxmox?
Key reasons: The massive price increases following the Broadcom acquisition, the elimination of perpetual licenses, forced bundle licensing, and uncertainty about VMware’s future. Proxmox offers comparable features at a fraction of the cost.
