If you are a RW user and don’t have an FTP App this you should seriously consider getting this to provide all of your FTP needs. Use RW to Export or Publish to a local folder and then use Yummy FTP to do all of the FTP work. You will never have an FTP problem again.
On a side note really concerning that such a good App (part of Setapp too) is being discounted at 97% off!
I compared Yummy’s speed to Fetch and Transmit about two years ago. Yummy was fastest. But Fetch and Transmit may have improved since then. And it may have been dependent upon my particular host. Again, that was two years ago. But I always say, stick with what you know works for you. (Unless Yummy’s sister apps would be a benefit to you.)
There are a lot of outstanding FTP clients out. FileZilla (open source) does work well. The interface may be a bit confusing for new users as it has a lot going on. Yummy for .99 is a great deal if you don’t have one.
