GHSwitch is a lightweight desktop app for macOS and Windows that lets you instantly switch between multiple Git user configurations from your system tray. No more git config commands — just click your profile in the tray. Add profiles with a name, email, and optional signing key (GPG/SSH). Switch between work, personal, and open-source identities in one click. Lives quietly in your system tray, starts at login if you want, and stays out of your way.
