Someone searching "Proxmox VE ISO download" is almost always about to install it directly onto bare-metal server hardware, not run it as a desktop app. Proxmox Server Solutions releases the full platform free under an AGPL open-source license, charging only for optional enterprise support subscriptions on top of the identical software. It is a Linux-based installer ISO meant to become the host OS itself, not something you install inside Windows or macOS. This page links to the current ISO and flags the repository choice that trips up first-time installs.
No-Subscription Repo vs Enterprise Repo
A fresh Proxmox VE install defaults to the paid Enterprise repository, which will show update errors if you have not bought a subscription — switching to the free No-Subscription repository in the web UI's sources list resolves this and is standard practice for home labs. Every feature, including clustering and live migration, works identically without a subscription; the paid tier is purely for support access and repository stability.
Because it takes over the whole disk as a bare-metal hypervisor, install it on dedicated hardware or inside a VM for testing, never on a machine you need dual-booting.
Who ends up using Proxmox VE
Homelab enthusiasts and small IT shops building their own hypervisor without licensing fees choose Proxmox VE.
- Homelab enthusiasts consolidating multiple services onto one server using VMs and containers
- Small businesses replacing costly VMware licenses with a free bare-metal hypervisor
- IT admins testing server configurations in isolated VMs before deploying to production
Before you install
A couple of things worth knowing about Proxmox VE before you request the link: it only ships for Linux, so double-check that's the machine you're installing it on before you request the link. And on pricing, Proxmox VE is open source, so the installer is free with no trial timer, feature lock, or upsell screen to click past. It's developed and maintained by Proxmox Server Solutions.
System requirements
- Linuxmost current 64-bit distributions; look for a native .deb/.rpm/AppImage or a package in your distro's own repository
Heavier workloads (large files, high-res media, big projects) will naturally want more RAM and a faster CPU/GPU than the bare minimum.
Quick steps
- Download the Proxmox VE ISO and write it to a USB drive
- Boot the target machine from the USB and follow the installer's disk setup
- After first boot, switch to the free No-Subscription repo before running updates
Proxmox VE: the honest trade-offs
- Combines KVM virtual machines and LXC containers in one UI
- Every feature, including clustering, works without a paid subscription
- Strong fit for home-lab and small-business hypervisor builds
- Takes over the entire disk, so no dual-booting
- Default Enterprise repo shows update errors until switched

Keeping Proxmox VE up to date
Since Proxmox VE is open source, most Linux distributions keep it current through their own package manager. On Windows/macOS, re-running the installer from the official site (or an updater built into the app, if it has one) gets you the latest release. Sticking to the developer's own distribution channel — which is what this page links to — means you're never stuck on an old build with unpatched bugs just because a mirror site stopped updating its copy.
