Garuda Downloader is a user-friendly ISO downloader focusing on saving bandwidth via delta downloads by utilizing zsync2. It provides an easy UI for downloading the latest (official, not development) live images of all official editions. On Linux, you can manually select an older ISO file as a "seed" file in order to save bandwidth.
After an ISO file has been downloaded, it provides a button to quickly launch a recommended flashing tool (Etcher on Linux, Rufus on Windows (only because the Rufus executable is tiny)). This is the recommended way to download Garuda Linux.
