Satisfactory Mod Loader review
A free, developer-focused framework for building and loading Satisfactory mods.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Satisfactory Mod Loader (SML) is an unofficial, open-source Unreal-based mod loader and framework for Satisfactory. It is aimed at both mod developers and players: developers use it to build and package mods, while players typically install it through Satisfactory Mod Manager. SML loads mods from the game's Mods directory and automatically discovers and bootstraps their modules, giving Satisfactory's modding ecosystem a shared foundation.
Its strongest area is lifecycle and game-system support. SML provides game-instance, menu-world, and game-world lifecycle modules, along with content registration for schematics, research trees, chat commands, and other systems. Developers can also define custom configurations and keybindings, declare Unreal plugin and mod dependencies, check game-version compatibility at runtime, and enable cross-mod interaction through accessible root modules. This makes it a fit for projects that need more than basic file loading or a narrow single-purpose modification.
SML is free and open source, with support for Windows and Linux. The plugin-based approach includes dependency management and is focused specifically on Satisfactory, so it suits developers building within that game rather than teams seeking a multi-game loader or a hosted mod platform. Players should also distinguish SML from Satisfactory Mod Manager: SML provides the loader and framework, while SMM is the player-facing installer. Choose SML for Satisfactory mod development and framework-level capabilities; consider an alternative if you need broader game coverage or a hosted service.
