Overview

Cyberduck is a file-transfer and cloud-storage browser for Mac and Windows, best suited to people who connect to several kinds of servers or cloud services. Its breadth of protocols, synchronization preview and open-source license make it a capable general-purpose choice; readers focused on a single transfer protocol may prefer a narrower client.

Key features

Connections and transfers

Cyberduck connects to FTP, SFTP, WebDAV and SMB servers, alongside OpenStack Swift, Google Cloud Storage, Amazon S3, Azure and Backblaze B2. It also supports OneDrive, SharePoint, Google Drive, Box, Dropbox and other services. That range can reduce the need to switch applications when files are spread across storage providers. Transfers support drag and drop, recursive directories, resuming interrupted transfers and copying directly between servers. Automation is supported, but scheduled transfers are not, so it is not the right fit for workflows that depend on a built-in timetable.

Synchronization, editing and sharing

Cyberduck can synchronize local and remote directories and preview affected files before acting. That is useful for checking the scope of a sync before making changes. It can open server files in a preferred external editor, and copy or open HTTP URLs. S3 users can also work with CDN and pre-signed URLs. Modification dates cannot be retained across every protocol, which matters for workflows that rely on timestamps surviving a transfer.

Security and integration

For SFTP, Cyberduck supports strong ciphers, public-key authentication and two-factor authentication. Passwords are kept in the system Keychain, and certificates are checked against Keychain trust settings. Cryptomator integration adds client-side encryption, including encrypted filenames, obfuscated directory structures and individually encrypted files. Cyberduck's site says the software has no backdoors and requires no account or registration. It also integrates with Finder, Windows notifications, Bonjour discovery and system protocol handlers.

The GPL license and public source code will appeal to readers who value open software. Community help, documentation, a public bug tracker and email support provide support channels. Cyberduck CLI is available for Mac, Windows and Linux, extending the command-line option beyond the desktop application's two platforms.

Pricing

Cyberduck is freemium. The GPL-licensed Free software plan costs 0.00 USD per free and requires no registration or account. It is the straightforward choice for anyone who wants the application without paying or entering a registration flow.

The Registration key costs 10.00 USD per month, billed as a minimum contribution shown by the vendor. It disables the donation prompt and provides a personal key usable on multiple computers, making it suitable for someone who wants to contribute while using more than one machine. The Registration key contribution is 10.00 USD per once, the minimum amount, and likewise disables the donation prompt and works on multiple computers. That key is personal and cannot be shared. These are contribution-based registration options rather than feature tiers; both retain the same stated multi-computer use, while only the one-time key has an explicit non-shareable term.

Platforms

The desktop application supports macOS and Windows. Current downloads require Windows 10 64-bit or later, or macOS 10.13 or later on Intel or Apple M1. The separate Cyberduck CLI is available for Mac, Windows and Linux.

Who it's for

Cyberduck is a strong match for people managing files across several protocols and cloud providers, especially those who value direct server-to-server copying, sync previews or client-side encryption through Cryptomator. Its free GPL option also suits readers who want a no-account desktop client. Look elsewhere if scheduled transfers are essential, if modification dates must be preserved across every connection, or if your device does not meet the stated desktop requirements.

Pros and cons

Pro: Broad server and cloud coverage makes one client practical for varied storage connections.
Pro: Resumable and recursive transfers, direct server-to-server copying and sync previews cover more than basic upload and download workflows.
Pro: SFTP authentication choices, Keychain credential handling and optional Cryptomator encryption provide several layers of security control.
Pro: The free GPL plan needs no registration or account, and paid registration keys can be used on multiple computers.
Con: Scheduled transfers are not supported, limiting unattended, time-based workflows.
Con: Modification-date retention varies by protocol, so timestamp-dependent workflows need checking.
Con: The desktop app is limited to Mac and Windows, with minimum OS versions that may rule out older systems.

Alternatives

For a narrower FTP or SFTP search, browse FTP and SFTP clients, SFTP Client Software or WebDAV Client Software.

FTP Rush is a free alternative available on Android, iOS, Linux, Mac and Windows, with no paid limits stated. Choose it if broader device coverage matters more than Cyberduck's stated cloud and protocol range.

FileZilla Client is a free Linux, Mac and Windows client for FTP, FTPS and SFTP. It is a fit if those transfer protocols are your focus.

WinSCP is a free, open-source Windows client supporting SFTP, FTP, FTPS, SCP, WebDAV and S3. Choose it if you want a Windows-only transfer client with that protocol mix.

CrossFTP is another freemium client for Linux, Mac and Windows, with a free plan and paid Pro and Enterprise plans for one computer. Consider it if that platform and plan structure suits you.

lftp is free, GPL-licensed software for Linux. It may suit Linux users seeking a command-line-oriented alternative.

FTPie is a Windows freemium client whose free plan is limited to one device and three server connections. Its Pro Monthly plan allows three devices and unlimited connections; pick it if those connection limits are the relevant distinction.

Core FTP is a Windows freemium option with Standard and Pro single-user licenses. It is an alternative for Windows users comparing those license tiers.

sFTP Client is a freemium option for Windows, Mac and Linux. Consider it as another cross-platform client.

Verdict

Choose Cyberduck if you need one Mac or Windows application for varied server and cloud connections, and value sync previews, transfer flexibility and optional client-side encryption. Its GPL free plan makes it easy to start without an account. Look elsewhere if scheduled transfers, universal modification-date retention or support for a different desktop platform is central to your workflow.
