UEDumper #

Open Source ★ 1.3k Updated 2026-04

GUI-based, engine-aware dumper for Unreal 4.19 to 5.3+. Iterates GUObjectArray and GNames to generate compilable C++ SDKs and MDKs (Mapping Data Kits).

Pro Tip: The 'offline mode' is perfect for analyzing a dump without having the game running.

Dumper-7 #

Open Source ★ 1.9k Updated 2026-05

The gold standard for generating Unreal Engine C++ headers. While other dumpers might give you messy code, Dumper-7 is built to produce clean, compilable SDKs that you can drop directly into your Visual Studio project.

Pro Tip: If your generated SDK is giving you a million compiler errors, switch to Dumper-7. It handles the weird 'bitfield' alignment issues that break other dumpers.

UE4SS #

Open Source ★ 2.5k Updated 2026-05

The gold standard for modern Unreal Engine modding (UE4 and UE5). It is the engine under the hood for almost every 'Internal' mod menu you see. It lets you run Lua scripts and peek at live properties while the game is actually running.

Pro Tip: The live property editor is a lifesaver. You can find a variable like 'bIsGodMode', flip it in the GUI, and see if it actually works before you waste hours writing a C++ injector.

FModel #

Open Source

The best way to look at Unreal Engine assets without actually opening the engine. It is perfect for 'ripping' models, textures, and most importantly, looking at .usmap files to find property names that the game dev tried to hide.

Pro Tip: Use this to find the exact names of objects (like 'PlayerPawn') before you start writing your dumper logic.

A simple way to force-enable the developer console and noclip in Unreal Engine games. You just inject it and you're good to go—no actual RE required.

Pro Tip: The easiest way to get 'God Mode' or 'Noclip' in a UE game without actually reverse engineering it. Just inject and press the tilde key.
