Rsyncinator Desktop is an open source and multi-platform app for generating
rsync commands to use in your terminal.
This app is available to download for free, but please considering donating if you find the project useful!
The web version is available to use here and works similar to this app.
If you use a Mac with Big Sur or Montery please consider the native desktop app for better performance and a more Mac-like experience.
