What R2ModMan does

R2ModMan is a free client wired to Thunderstore: browse packages, toggle them per profile, and launch modded or vanilla sessions without manual BepInEx copying.

Profiles isolate lists and configs — flip from light QoL sets to heavy overhaul packs instantly, then export a code so co-op groups share identical stacks.

Mod assets live beside, not inside, vanilla installs. Updates queue while you play and apply on exit; configs edit in-place without spelunking AppData trees.

Quick facts

+ 9M+ Thunderstore package pulls
+ Current build: 3.2.17
+ Windows setup plus Linux AppImage
+ MIT open-source codebase
+ Updates finalize after you quit the app
