Cyberduck: A GUI File Transfer Tool That Handles Servers and Clouds Equally Well
Some tools are made for developers. Others for sysadmins. Cyberduck feels like it was built for both — and somehow still works for everyone else, too.
It’s a graphical file transfer client for Windows and macOS that supports just about every protocol you might need: FTP, SFTP, WebDAV, Amazon S3, Backblaze B2, Google Cloud, Azure, and more. It looks like a basic file browser, but behind the clean interface is a lot of power — smart handling of large files, sync support, bookmarks, cryptomator encryption, and tight cloud integration.
If you need to move data between your machine and the internet — whether that’s a Linux server or a cloud bucket — Cyberduck just quietly does the job.
Why People Actually Use It
Feature | Why It’s Handy in Real Life
——–|———————————————————————-
Multi-Protocol Support | FTP, SFTP, WebDAV, S3, OpenStack Swift, Backblaze, Azure, Dropbox…
Cloud-Ready | Direct access to object storage — browse it like a file system
Drag-and-Drop UI | Intuitive, familiar — no CLI gymnastics required
File Sync Support | Mirror folders between local and remote — useful for staging/deploys
Bookmark Manager | Save server configs, creds, paths — switch between them instantly
Cryptomator Integration | Encrypt files before upload, zero-knowledge
Resume & Retry Uploads | Especially helpful on big files or shaky connections
Command-Line Duck Tool | Optional `duck` CLI utility for scripting (install separately)
External Editor Support | Edit remote files in your IDE or text editor, auto-upload on save
Who It’s Made For
– Developers syncing files to staging servers or cloud storage
– Web admins managing SFTP/WebDAV for hosted sites
– Designers uploading assets to S3 or CDN endpoints
– Backup operators pushing archives to Backblaze or Glacier
– Anyone who wants a clean GUI for complex remote storage tasks
Cyberduck is especially useful when you’re switching between protocols all day and don’t want six different tools to do the job.

Final Thought
Cyberduck doesn’t try to be a developer IDE or an enterprise dashboard — it’s a well-built, focused file transfer tool that gets out of the way and just works. Whether you’re connecting to a server in your rack or a bucket in the cloud, it gives you one consistent way to interact with remote files — and that, frankly, is rare.
