About R2ModMan

R2ModMan is a free Thunderstore front-end: pick a game, build a profile, install packages, toggle mods, and launch modded or vanilla sessions without manual BepInEx copying.

Profiles isolate lists and configs—swap from minimal QoL to total overhauls instantly, then share codes so co-op groups match versions.

Mod files stay out of vanilla directories, updates finish after close, and the built-in editor adjusts configs without spelunking disk paths.
