## What it is
VMAware is a cross-platform, header-only C++ library for detecting virtual machines, hypervisors, emulators, containers, and sandboxes using around 90 unique detection techniques across ~70 VM brands. It also ships with a companion CLI tool that exposes the library's full detection capabilities.

## Use cases
- detect if my application is running inside a VM
- check which hypervisor brand the host is using
- detect QEMU or VirtualBox from C++ code
- add anti-VM checks to anticheat software
- detect VM hardening attempts
- identify sandboxes and containers from a native app
- scan a machine for virtualization from the command line

## When to choose
- you need robust, multi-technique VM detection in C++ with no dependencies
- you want cross-platform (Windows/macOS/Linux) and multi-architecture support
- you need fine-grained control over which detection techniques run
- you want a ready-made CLI for quick virtualization checks

## When to avoid
- you need VM detection in a language without access to the C++ ecosystem or its ports
- your goal is to evade detection rather than perform it
- you need a managed/high-level service rather than a native library
- your project cannot tolerate the ethical/legal implications of anti-VM checks
