Free GUI-based mod installer
Quest Patcher is a game utility developed by Lauriethefish. It works as a GUI-based mod installer for any il2cpp unity app on the Oculus Quest that runs on Windows. The app is free to download and uses Sc2ad's Questloader for loading mods. It is also based mostly on RedBrumbler's CLI Tool.
Quest Patcher was created for modding Gorilla Tag. With this, you can use the app to install, update, and uninstall mods for the popular virtual reality game. However, note the app only officially supports Windows 10. You can install it to other versions, but full functionality is not guaranteed.
