About this project

r2modman is a simple and easy-to-use mod manager for several games that use Thunderstore, including Risk of Rain 2, Dyson Sphere Program, Valheim, GTFO, and BONEWORKS. It provides a clean interface to simplify modding, with safer installation that allows playing through Steam normally. Key features include mod profiles for switching between different mod sets, exporting profiles to share mods and configs with friends, downloading and installing mods directly from the manager, viewing and updating outdated mods, editing configs in-app, and automatic updates. Installation is available for Windows via a setup executable, and for Linux via Flatpak (recommended for Steam Deck) or AppImage, with platform-specific builds (deb, rpm, pacman, tar.gz) also available. The manager auto-updates when available. For help, users can check the wiki or join the community Discord. Feedback and suggestions are welcome, with consideration for less experienced users.
