Proxmox VE vs TrueNAS
Pick Proxmox VE if the job is VMs and containers (KVM/LXC on Debian). Pick TrueNAS if the job is a ZFS NAS appliance. They solve different boxes — many homelabs run VMs on one and disks on the other.
Facts checked 18 Oct 2026. License, language, and GitHub activity come from the catalog or the project's own repo. "Not in the catalog row" means the public catalog dump does not store that number.

How they compare
| Proxmox VE | TrueNAS | |
|---|---|---|
| License | AGPLv3 (Proxmox VE FAQ) source | Open-core: LGPLv3/GPLv3 community middleware; some enterprise modules commercial source |
| Language | Debian GNU/Linux based (Perl/Python in the stack; not a single GitHub language) | Python (truenas/middleware) |
| GitHub activity | Source on git.proxmox.com — no GitHub star count in the catalog | 2,607 stars on truenas/middleware in the catalog source |
| Self-host | ISO on a server. KVM + LXC. Enterprise repo is paid. | NAS appliance OS (SCALE is Linux; CORE was FreeBSD). Disks first. |
| Best for | Virtual machines and containers. | ZFS storage you share. |
Self-hosting and resource needs
Proxmox VE is AGPLv3 (pve.proxmox.com FAQ / features page). Source is on git.proxmox.com. A subscription buys the enterprise repo and support, not the license — the no-subscription repo stays available. TrueNAS Community middleware is LGPLv3/GPLv3 on truenas/middleware; iXsystems documents commercial modules (HA, Fibre Channel, FIPS). Unraid is proprietary and is not this pair. Bare metal, not Railway.
FAQ
- Can I run both?
- Yes. Typical split: Proxmox for VMs, TrueNAS for disks (or TrueNAS VMs on Proxmox). Pick the job on day one.
- Where is Unraid?
- Unraid is not open source. This page compares Proxmox VE to TrueNAS.
- Is Proxmox free without a subscription?
- The software is AGPLv3. Subscriptions are support plus the enterprise repo. The no-subscription repo is documented by the project.
- Is this Coolify?
- Coolify is an app PaaS on Docker (/compare/coolify-vs-dokploy). Proxmox is the hypervisor under the VMs.
