Stellar Mod Loader

What Stellar Mod Loader is
Stellar Mod Loader is a free mod manager for Windows and Linux, including native Steam Deck support. It is built for games such as Oblivion, Skyrim, Fallout titles, and Starfield. Users can manually import mods, detect conflicts, and add, reorder, rename, disable, or remove mods and plugins. Profiles switch between games and mod loadouts; base profiles can pass mods, plugins, and configuration files to other profiles. Each profile can manage configuration files, save files, and archive invalidation. Stellar supports FOMOD installers, describes BAIN-style packaging support, and handles root mods such as ENBs, script extenders, DLSS injectors, and other injectors. Built-in definitions cover listed Oblivion, Skyrim, Fallout, and Starfield versions, while custom game definitions can be created, imported, and exported. Steam, UWP/Game Pass, and other game versions are supported. A command line can activate a named profile and launch a game or custom action. 7-Zip is required.
Who it suits
Stellar suits Windows or Linux players who maintain multiple modded games and want separate loadouts, profile data, and conflict detection. It also fits users managing custom game definitions or root-level injectors.
