QEMU vs UTM

QEMU: what it's good at

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.

• Emulates multiple CPU architectures
• Near-native speed with KVM acceleration
• Extensive virtual hardware support
• Foundation of many virtualisation stacks

UTM: what it's good at

UTM is the practical way to run Windows or Linux on a Mac, and one of very few options built properly for Apple Silicon. It wraps QEMU in a native macOS interface, supporting both fast virtualisation of matching architectures and slower emulation of others.

• Native Apple Silicon support
• Virtualise or emulate other architectures
• Native macOS interface
• Free and open source

Which should you choose?

Both are free, so the honest answer is that you can install either and decide for yourself — that is the advantage of free software over a paid trial.

Both run on macOS. Only QEMU supports Windows, Linux. Only UTM supports iOS. Both are open source, so neither locks you in.

We deliberately do not publish a star rating for either. We have no way to verify a rating that would be honest at scale, and an invented one would be worse than none — so we give you the facts and let you decide.

Frequently asked questions

Is QEMU better than UTM?

Neither is universally better. QEMU powerful machine emulator and virtualizer, while UTM virtual machines on macOS, including Apple Silicon. The right pick depends on your platform and workflow.

Are both really free?

QEMU is open source and UTM is open source. Both can be downloaded without paying.

Can I install both?

Yes. Since neither costs anything, installing both and comparing them on your own files is usually the fastest way to decide.
