## What it is
UTM is a full-featured system emulator and virtual machine host for iOS and macOS, built on QEMU. It lets users run Windows, Linux, and other operating systems on Macs, iPhones, and iPads, with hardware-accelerated virtualization on macOS and a JIT-free 'SE' edition for non-jailbroken iOS devices.

## Use cases
- run windows on a mac
- run linux on iphone or ipad
- emulate x86_64 arm64 or risc-v systems on apple devices
- test software in a virtual machine on macos
- run a vm without jailbreaking ios
- boot macos guests on apple silicon

## When to choose
- you need to run other operating systems on iOS or macOS
- you want a free, open-source VM frontend with a native UI
- you need emulation of 30+ processor architectures including RISC-V and PPC
- you want hardware-accelerated virtualization on macOS via Hypervisor.framework

## When to avoid
- you need GPU virtualization, DirectX, or OpenGL for gaming
- you need near-native performance on iOS, since TCG JIT emulation is slower than KVM
- you want to run iOS itself as a guest
- you need a server-grade hypervisor for Linux or Windows hosts
