Modrex review
A free open-source manager for browsing, installing, organizing, updating, and launching supported game mods.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Modrex is a free, open-source desktop mod manager for Windows and Linux. It is designed for players of PAYDAY 3, PAYDAY 2, PAYDAY: The Heist, Crime Boss: Rockay City, and RAID: World War II who want one application for finding, installing, organizing, updating, and launching mods. Users can browse ModWorkshop catalogs inside the application, access Nexus Mods for supported games, install local archive files, and detect supported game installations across Steam, Epic Games Store, and the Xbox App.
The product’s strongest area is its built-in mod workflow. One-click installation from supported catalogs sits alongside enable, disable, uninstall, and reinstall controls. Mods can be organized into nested folders, with load-order control for managing how enabled content is arranged. Modrex also detects outdated mods and supports both selective and bulk updates. Its Health Check covers missing files, broken archives, outdated installs, and dependencies, while game launching can include enabled mods or temporarily run without them. Certain required mod loaders can also be installed automatically.
Modrex is a focused choice rather than a general-purpose manager for every game. Its catalog browsing, automatic installation, and launcher detection depend on supported games and integrations, while its documented platform support is limited to Windows and Linux. The integration set includes ModWorkshop, Nexus Mods, Steam, Epic Games Store, Xbox App, and Discord Rich Presence. Players within the supported PAYDAY and related-game group should find the feature set well aligned with routine mod maintenance. Those seeking broad coverage beyond these games or platforms should choose a manager built around a wider catalog and operating-system range.
