OneButton FTP is a project with the goal of creating an open source graphical FTP client for Mac OS X (10.3.9 and above) using the Cocoa framework. There are a lot of nice graphical FTP clients for OS X out there right now, but none seem to have all the features everyone wants. Specifically, many of the current offerings don't offer a lot in the way of an advanced queuing system. Also, most of the good clients are not open source or free software! OneButton FTP plans to change all this by bringing to the table a graphical FTP client for OS X that is Free Software (licensed under the terms of the GNU GPL) and has all of the great features users desire.
