Cyber Engine Tweaks vs RED4ext

Cyber Engine Tweaks is a free framework for scripting mods for Cyberpunk 2077 with Lua and access to internal game scripting features. It includes a Dear ImGui interface for mods, a console and a TweakDB editor, along with developer options such as diagnostics, assertions, a debug menu and logging game options. Included patches can be enabled or disabled through settings or configuration files, though changes require restarting the game. Examples include removing pedestrians and traffic, disabling temporal antialiasing, suppressing intro movies and skipping the start menu. RED4ext is a prerequisite. The project distributes current releases through GitHub Releases and provides wiki documentation for installation, usage and modding. Windows is supported; Linux instructions cover use through Proton, including Steam and non-Steam/Wine setups. Release notes for Patch 2.31 list support for game version 2.31. The repository includes an MIT license permitting use, modification and distribution subject to its conditions, and provides the software without warranty.

RED4ext is a free Windows script extender and plugin manager for Cyberpunk 2077. It gives modders access to the game's scripting system so plugins can add features, alter behavior, add scripting functions, or call existing game functions. RED4ext loads plugins only for supported game runtime versions, while also allowing plugins aimed at the latest defined runtime or independent of runtime versions. RED4ext.SDK exposes the scripting virtual machine, native classes and functions, and reversed game structures. Developers can use any toolchain that produces x86-64 output with the __fastcall calling convention, including CMake, Premake, or Visual Studio. Plugins can attach custom game states around game-system availability and are placed in red4ext/plugins. Each plugin receives a logger, with named logs under red4ext/logs. Configuration is TOML stored in red4ext/config.ini, where plugin loading and individual plugins can be disabled. The MIT-licensed project lists v1.30.0 as its latest release.
