If you actually need to be productive, don't bother with this app. If you want a toy SSH and FTP client that will be used to move one or two. I think the only hope for this app is to be rewritten from scratch. Cyberduck is a libre server and cloud storage browser for Mac and Windows with support for FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive and Dropbox. The problems are many, random, impossible to reproduce, and therefore impossible to report.

And the crashes, for reasons unknown to me, don't show the macOS crash report dialog that you normally see. The worst part is, the 'unknown error' alerts happen entirely randomly, there is no way to reproduce the bug, so it's impossible to report it to the dev. It's incredibly frustrating and rather than aiding me at doing my job, it makes it even more frustrating. Ocassionally it will randomly give you 'unknown error' alerts and you will be BOMBED with them (you really have to dismiss hundreds of them at a time - one by one). It crashes all the time for no apparent reason. Advanced users will not be the only ones to enjoy it users that are. Advanced users will fall in love with all they can do to this browser that has been subjected to a hard testing bench: the Asian community.

Sleipnir stands out for its customizable capability using plugins. A few months ago I started doing heavy SSH and FTP related work, mostly with moving files around in a server. Sleipnir is one you can choose for completely reliable web browsing. I bought this app many years ago and I used it ocassionally for light FTP tasks.
