Mod Organizer 2
Mod Organizer 2 is a free, open-source Windows tool for managing game mod collections through a virtualized setup. It supports installing and uninstalling mods, organizing profiles, detecting conflicts, and automatic updates. The project describes it as a tool for people who experiment with mods and says it can handle collections of arbitrary size. Supported games include 64-bit titles such as Skyrim Special Edition and Fallout 4, along with the 32-bit games supported by Mod Organizer 1. Its basic games plugin can detect installations from Steam, GOG, Origin, Epic Games or Legendary, and EA Desktop. A mod data checker can identify and correct archive layouts for automatic installation. Downloads are available through GitHub Releases and Nexus Mods; the installer can also create a portable installation. Version 2.5.0 requires Windows 10 1809 or newer, or Windows 11. The virtual filesystem does not work with Windows Store or Gamepass packaging, so those versions of otherwise supported games are not usable. The community-maintained project is licensed under GPL-3.0.
