About QEMU
QEMU both virtualises and fully emulates hardware, so it can run operating systems built for entirely different processor architectures. It underpins a great deal of Linux virtualisation infrastructure.
It is open source and runs on Windows, macOS, Linux. Below are 4 virtualization programs that cover the same ground — some open-source, some cross-platform, each free to use.

The alternatives in detail
VirtualBox Open Source
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.
VMware Workstation Pro Free tier
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 Open Source
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.
Proxmox VE Open Source
Proxmox VE installs directly onto hardware rather than inside an existing OS, managing virtual machines and containers through a web interface. Notable for installs bare-metal, managed via web ui and kvm virtual machines plus lxc containers. Runs on Linux.
How to choose
3 are fully open source (VirtualBox, UTM, Proxmox VE) — pick one of these if you value auditable code you can self-host. For the widest platform coverage, VirtualBox run on three or more operating systems. On a Mac, VirtualBox, 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.
