## What it is
The RAD Debugger is a native, user-mode, multi-process graphical debugger for Windows x64, currently in alpha, developed by Epic Games. It also includes the RAD Debug Info (RDI) format and the RAD Linker, a fast linker for large PE/COFF executables.

## Use cases
- debug native windows x64 applications with a fast graphical debugger
- debug multi-process native programs
- convert pdb debug info to a faster custom format
- link huge c/c++ executables quickly with pdb generation
- debug large game codebases with gigabytes of debug info

## When to choose
- you debug native windows x64 code and want a faster, more responsive alternative to visual studio's debugger
- you work on very large c/c++ projects where pdb generation or conversion is slow
- you want to try a modern multi-process graphical debugger and report issues

## When to avoid
- you need linux or macos debugging today
- you need dwarf debug info support, which is not yet implemented
- you need a battle-tested production debugger - this is alpha software

## Facets
- artifact type: application
- maturity: experimental
- function: editor, developer-tools, gui
- domain: developer-tools, windows
- platform: windows, cpp, cli
- tags: debugger, native-debugging, pdb, dwarf, rdi-format, linker, game-development, epic-games
