## What it is
HyperDbg is an open-source, hypervisor-assisted debugger for Windows (with Linux support in development) that uses Intel VT-x and EPT to debug user-mode and kernel-mode code. It offers hidden hooks, memory monitoring, and tracing via Intel PT for reverse engineering, fuzzing, and system analysis.

## Use cases
- debug windows kernel code invisibly with ept hooks
- trace memory reads and writes at specific addresses
- analyze malware with hypervisor-based introspection
- reverse engineer user-mode and kernel-mode binaries
- fuzz windows drivers with hardware-assisted breakpoints
- build vmi-based security research tooling

## When to choose
- you need stealthy, hypervisor-level debugging on Windows that traditional debuggers like WinDbg can't provide
- you're doing malware analysis or kernel research requiring hidden hooks and memory monitoring
- you want Intel PT-based tracing and virtual machine introspection capabilities

## When to avoid
- you need a debugger for Linux in production, as Linux support is still under development
- you only need simple user-mode application debugging without kernel or hypervisor features
- your hardware lacks Intel VT-x and EPT support
