Packer vs Proxmox VE
Proxmox VE
Software
Open-source hypervisor combining KVM and LXC virtualisation
- From
- €120/year
- Rated
- -
The short version
- Only Packer has a free tier, so it costs nothing to try first.
- Each has a real cost: Packer packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Packer
- Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
- The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
- Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
- Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence
Proxmox VE
- Per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
- Linux-based host only; Windows hypervisors not supported, limiting adoption in Windows-focused organisations
- Clustering and high-availability setup requires operational expertise and careful network configuration
- Commercial support tiers limit advanced features (just-in-time access, network flow logs) to paid subscriptions
- Smaller ecosystem of third-party plugins and integrations compared to VMware vSphere
