The Witcher 3 Mod Manager
What The Witcher 3 Mod Manager is
The Witcher 3 Mod Manager is a free utility for installing and organizing mods for The Witcher 3. It supports Original, Next-Gen, and Remastered installations, including Steam and GOG on Windows, Steam Proton on Linux, and CrossOver on macOS. Mods are imported manually from ZIP, RAR, or 7z archives. The manager can install, uninstall, enable, or disable multiple mods, display load order, and change priorities. When included in a mod, it can add mod menus, DLC files, custom input keys, and custom user settings. Script Merger remains separate; on Linux and macOS the manager launches it through Wine using the selected executable. Releases are available through GitHub Releases or Nexus Mods, and the repository uses a BSD-2-Clause license. Installation and removal are not fully transactional, and shared menu or base INI files are not restored when mods are disabled or removed.
