I am amazed that there doesn't seem to be a decent multiple connection capable FTP/SFTP client for Mac.

The only one I've seen is CaptainFTP, which looks awful, like it's from the last century.

There's also iGetter, which is equally ancient, and not really set up as a browser, more of a download accelerator.

I've been using lftp, which is amazing, but CLI only, which makes it a pain.

Does anyone know of either (a) a "modern" client app which supports multiple connections, or (b) a GUI for lftp?

  • Have you looked at Transmit? Supports multiple connections, SFTP and WebDAV, Amazon S3..

    Just tried it; but transfer capped out at 40 mbps. lftp gives me 100 mbps (the server limit.)

  • The only other recommend that I would have is Filezilla.

Old question, but I found that Cyberduck supports multiple connections. When transferring over SFTP, it's possible to select multiple connections in the upper-right of the progress dialog. Whether that has an effect on the total speed, I am currently not able to measure.


Have you checked out Fetch (http://fetchsoftworks.com) or Interarchy (https://nolobe.com/interarchy/)? They both allow simultaneous connections to multiple remote servers, remote-to-remote transfers, SFTP, and lots of other handy and solid features from long development histories with feedback from many users.

  • Tried both. Neither would go any faster than 20-25 mbps. And very uneven speed. lftp gives me consistent 100 mbps (limited by server internet bandwidth.)

  • Interesting - that's quite a difference. Does lftp achieve that through use of its ability to asynchronously issue multiple ftp commands? How does it do with just one large file? Jan 29, 2015 at 21:57
  • I have no idea how, I just wish it had a GUI!

Go get Transmit from Panic. It’s the gold standard in my opinion and experience. MountainDuck is my second choice (unless you can get along with the free Cyberduck)
