Petonexus is built independently. If you want to help Trails VR and Gymmons keep growing, you can support their development on Ko-fi.
A Windows-first mod manager for VR mods, performance tools, overlays, and game tweaks. Moddin detects installed games, previews every change, keeps backups, verifies installations, and can undo what it applied.
Its data-driven capabilities already cover workflows around UEVR, OpenXR helpers, OBS VR capture, OptiScaler, ReShade, and other game-specific tools.
