What r2modman is

r2modman is a free, open-source mod manager for games using Thunderstore. It supports titles including Risk of Rain 2, Dyson Sphere Program, Valheim, GTFO, and BONEWORKS. Users can download, install, update, enable, disable, and uninstall mods from the manager. Profiles let players switch between mod setups or export mods and configurations for sharing, and a built-in tool edits configurations directly. The project says updates download while the application is running and install after it closes. r2modman runs on Windows and Linux. Windows installation uses the setup executable in a Thunderstore manual download. Linux choices include Flatpak, AppImage, and deb, rpm, pacman, or tar.gz builds. For Steam Deck, Flatpak is recommended for game mode, with Flatpak or AppImage for desktop mode. Thunderstore, GitHub, and ebkr.dev are listed legitimate download sources. The repository uses an MIT license.
