RED4ext vs Satisfactory Mod Loader

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.

Satisfactory Mod Loader is an unofficial tool for loading mods in Satisfactory. It provides a framework to help mods work with game systems and with one another, along with helper features for mod developers. Mods can be written in Unreal Blueprint or C++, and community libraries also support JSON files. The Satisfactory Mod Manager installs the loader, mods, and dependencies, and connects to the Satisfactory Mod Repository; the project recommends using the manager rather than installing SML manually. The repository says uploaded content is checked for malware before approval for download. SML is designed with multiplayer support in mind, and its developer says it makes no connections to external networks. The project also says uninstalling the loader will not cause loss of items or progression. No required dependencies are listed. The project includes source code, an ExampleMod demonstrating utilities, editor utilities, and the Unreal project used for mod development. Windows clients and servers are supported; Linux support is listed for servers, while Linux client support is marked N/A. Controller support is untested. The project displays a GPL-3.0 license and directs users to Discord for discussion.
