4 virtualization programs worth considering instead of — or alongside — Proxmox VE.
Run Windows, Linux and other systems in a window.
Powerful machine emulator and virtualizer.
Commercial-grade desktop hypervisor, free for personal use.
Virtual machines on macOS, including Apple Silicon.
Proxmox VE installs directly onto hardware rather than inside an existing OS, managing virtual machines and containers through a web interface. It is the standard choice for home labs and small-business servers, offering clustering and live migration free.
It is open source and runs on Linux. Below are 4 virtualization programs that cover the same ground — some open-source, some cross-platform, each free to use.
| Program | Licence | Platforms | Best known for |
|---|---|---|---|
| VirtualBox | Open Source | Windows, macOS, Linux | Runs Windows, Linux and BSD guests |
| QEMU | Open Source | Windows, macOS, Linux | Emulates multiple CPU architectures |
| VMware Workstation Pro | Free tier | Windows, Linux | Free for personal, non-commercial use |
| UTM | Open Source | macOS, iOS | Native Apple Silicon support |
VirtualBox runs complete guest operating systems inside your current one — ideal for testing software safely, running legacy applications, or learning Linux without touching your existing installation. Notable for runs windows, linux and bsd guests and snapshots to roll back a machine instantly. Runs on Windows, macOS, Linux.
QEMU both virtualises and fully emulates hardware, so it can run operating systems built for entirely different processor architectures. Notable for emulates multiple cpu architectures and near-native speed with kvm acceleration. Runs on Windows, macOS, Linux.
VMware Workstation Pro became free for personal use in 2024, putting a long-established commercial hypervisor within reach of home users. Notable for free for personal, non-commercial use and strong 3d and hardware acceleration. Runs on Windows, Linux.
UTM is the practical way to run Windows or Linux on a Mac, and one of very few options built properly for Apple Silicon. Notable for native apple silicon support and virtualise or emulate other architectures. Runs on macOS, iOS.
3 are fully open source (VirtualBox, QEMU, UTM) — pick one of these if you value auditable code you can self-host. For the widest platform coverage, VirtualBox, QEMU run on three or more operating systems. On a Mac, VirtualBox, QEMU, UTM support macOS natively.
All 4 are free to download from the publisher's own website, so installing two or three and testing them on your own files is the fastest way to decide — it costs nothing but a few minutes.
