Install SugarSubstitute
Download the installer for your platform:
Windows x64 installer
macOS Apple Silicon installer
Linux x86_64 AppImage installer or Debian package
The macOS installer is ad-hoc signed but not notarized. macOS will warn that it cannot verify the developer, so allow it through Privacy & Security after downloading it from this repository.
Already installed? Open SugarSubstitute normally. It checks for application updates when it starts, usually once per day, and installs newer application versions automatically. You normally do not need another installer.
