Satisfactory Mod Loader

What it is

Satisfactory Mod Loader (SML) is a free, unofficial tool that loads mods in Satisfactory. It supplies a framework for mods to work with game systems and with one another, along with helper features for mod development. 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 their dependencies, and connects to the Satisfactory Mod Repository; the project recommends using the manager rather than installing SML manually. The listing describes SML as designed with multiplayer support in mind, and the developer says it makes no connections to external networks. The project also says uninstalling it will not cause loss of items or progression. Version 3.12.0 is listed as working with Stable and Experimental versions of Satisfactory. Windows client and server support are listed, while Linux support is for servers and Linux client support is marked N/A. The mod is categorized as a library, which usually does not provide functionality on its own. The repository includes source code and development examples, and the project points users to Discord for discussion.
