## What it is
Cyberduck is a libre file transfer and cloud storage browser for macOS and Windows, with a CLI for Linux, macOS, and Windows. It supports FTP, SFTP, WebDAV, SMB, Amazon S3, OpenStack Swift, Backblaze B2, Azure, OneDrive, Google Drive, Dropbox, and more, with Cryptomator vault encryption.

## Use cases
- upload files to an s3 bucket
- browse and transfer files over sftp
- access google drive without syncing
- connect to nextcloud via webdav
- encrypt cloud storage with cryptomator
- transfer files to backblaze b2
- manage azure blob storage from desktop
- script file uploads with a command line interface

## When to choose
- you need a GUI client for many protocols and cloud providers in one app
- you want a libre (GPL) alternative to proprietary transfer clients
- you need client-side encryption via Cryptomator
- you want a CLI for scripted transfers on Linux, macOS, or Windows

## When to avoid
- you need to mount remote storage as a local disk (use Mountain Duck instead)
- you need a lightweight single-protocol tool
- you require a Linux GUI (the Linux offering is CLI only)
