Mac OS X only: Manage your FTP connections for free with Cyberduck. If you hate the idea of paying $30 for Transmit, give Cyberduck a whirl. Although not quite as advanced as Transmit, Cyberduck is nothing to scoff at. In addition to having an easy to use interface, Cyberduck also integrates with Growl and has a dashboard widget for easy drag-and-drop uploading. I've been using Cyberduck to manage my websites for about six months without any trouble. Cyberduck is a free download for Mac OS X only. Thanks, sgodun!
