In their own words
UAssetGUI
UAssetGUI is a desktop tool for examining and modifying Unreal Engine game assets by hand. It supports .uasset, .umap, .usmap, .utoc and .ucas files, as well as JSON. Windows is supported directly; Linux setup runs the Windows executable through Wine. Command-line arguments can export and import UAssetAPI JSON without opening the graphical interface, and custom C# scripts can extend the program. Portable mode, available in v1.1.0 or later, keeps configuration and saved mappings in a Data folder beside the executable. The v1.1.0 release added opening and saving .utoc and .ucas containers through built-in retoc integration. Pre-built binaries and an experimental build are available from the repository’s Releases page. Release notes report support for Unreal Engine 5.6 and 5.7, while earlier notes identify limits for some Unreal Engine asset support. UAssetGUI is free under the MIT License, which provides the software without warranty. The maintainer announced retirement from UAssetGUI development, though future contributors or releases might follow.
WolvenKit
WolvenKit is a free, open-source modding tool focused on Cyberpunk 2077 and REDengine 4. It can browse, extract, modify and repack game files into archives for use in the game. The Asset Browser previews meshes and textures from base-game or user-generated archives. Its RTTI-based File Editor reads and saves REDengine files, handles in-place buffer data, and converts game files to human-readable JSON and back. Project Explorer organizes files and opens source assets such as blend, PSD and XCF files. Asset conversion tools cover listed texture and model formats, with Blender one-click imports for shaded Cyberpunk meshes. Stable and nightly builds come through GitHub releases. Windows 10/11 64-bit and Linux are supported, although Linux compatibility is described as unstable and not guaranteed. The latest .NET 10.0 runtime and x64 architecture are required.
