What is R2ModMan?

R2ModMan is a free mod manager that connects directly to Thunderstore so you can browse, download, enable, disable, and update mods from one clean interface. Instead of manually copying files into BepInEx folders, you select your game, create a profile, pick mods, and launch with a single click.

Each profile stores its own mod list and configuration. Switch between a lightweight vanilla-plus setup and a full overhaul pack in seconds. Export profiles as a shareable code or file so friends can match your exact mod stack for multiplayer sessions.

The manager keeps mod files isolated from your original game installation. Updates download in the background and install when you close the app. An integrated config editor lets you tune mod settings without hunting through folders.
