Plans
In their own words
Irony Mod Manager
Irony Mod Manager is a free, open-source alternative to the official Paradox launchers. It supports Crusader Kings III, Europa Universalis IV and V, Hearts of Iron IV, Imperator: Rome, Star Trek: Infinite, Stellaris, and Victoria 3 on Linux, macOS, and Windows. Mods are imported manually, organized into profiles, and assigned deterministic load order according to each game’s rules. Conflict handling differs by title: Stellaris has full solver support, HOI4 has analysis-only support, and other listed games use merging. Multiple merge strategies are available, and the manager can generate patch mods during conflict resolution. An external editor or merge/diff tool can be configured. Official binaries are published on GitHub Releases. Windows and Linux update downloads are signature-verified; macOS updates require manual replacement. The macOS Finder bundle is unsigned and unnotarized. Windows 7 is no longer officially supported, and mods cannot be uploaded to Steam Workshop.
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.
