Cyberduck

Cyberduck calls itself “a libre server and cloud storage browser for Mac and Windows”. It opens storage in a window of its own; to see storage in Finder, its makers sell Mountain Duck.

Moving From Cyberduck

The buckets stay where they are. Get Folder for Mac, choose In Your Cloudflare, sign in to Cloudflare and tick the buckets you open in Cyberduck. Each appears in Finder under Locations, and Cyberduck keeps working beside it.
