Irony Mod Manager vs Modrix

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.

Modrix is a game mod manager with graphical, terminal and command-line frontends built over one shared engine. It is presented as an open-source alternative to Vortex and has built-in support for 86 games, with additional games available through a community plugin registry. A browser extension passes Nexus Mods download links and session cookies to Modrix so it can download and stage files without a Nexus API key. On Linux, the project describes Steam and Proton as first-class options and says Modrix usually detects Steam-installed games for a one-click add-and-switch action. Deployment uses hardlinks where possible, backs up files before overwriting, journals changes for crash recovery and supports reversing deployments. Modrix surfaces conflicts between enabled mods and offers rules and per-file overrides to resolve them. The CLI supports scripting and JSON output, and an MCP server exposes engine functions as tools for agents. The project states that it has zero telemetry and that Lua game plugins are sandboxed. It is GPL-2.0-only and costs nothing.
