What Is Cyberduck? Complete Guide for File Transfer and Cloud Access
Cyberduck has so often been a key part of the Mac developer’s toolkit in recent years.” Cyberduck is an open-source FTP, SFTP, WebDAV, Cloud Files, and Amazon S3 browser for the Mac. Established in 2002, Cyberduck is a popular file transfer client for the Mac and is in use at virtually every major corporation.
This Swiss Army knife of file management has come from an FTP client to a complete cloud storage system to a remote B2/BackBlaze backup to a full-on remote file server. Whether you’re a developer managing server files or a business user managing cloud storage, you’ll be more effective by knowing what Cyberduck can do for you.
Today’s digital world is such precise work, filled with files scattered across numerous cloud platforms and servers, and it makes sense to have a tool you can rely on for file transfer that makes everything easier. Cyberduck is another program that falls squarely between common file management and more contemporary cloud-based services, with a number of advantages that most people haven’t quite discovered yet.
What Is Cyberduck and Why Does It Still Matter in 2025?
Cyberduck started life as an open-source FTP client for Mac users, which subsequently transformed into one of the most popular cross-platform FTP clients that happens to be compatible with Windows, too. The app can now be used on a Mac or a Windows machine, so people with computers of one or the other type can easily access it.
But what makes Cyberduck so different from plain old file transfer software is how adaptable it is. Although many utilities only connect to FTP, this tool also connects to SFTP, WebDAV, S3, Google Drive, and Dropbox.
The numbers are Jazz’s impressive story. Cyberduck has been downloaded more than fifty million times , and its users are located in more than 180 countries. But despite its popularity, it’s 100 percent free and has enterprise-level features for which other services charge hundreds of dollars per year.
Key Statistics That Show Cyberduck's Impact
The software remains relevant in 2025 because it solves a fundamental problem: file fragmentation across platforms. Instead of juggling multiple apps for different cloud services, Cyberduck provides one unified interface for all your file transfer needs.
Cyberduck vs FileZilla: Who Wins in 2025?
In the end, Cyberduck vs FileZilla is usually a question of preference and individual requirements. Both are great at transferring files, but they each cater to different users.
FileZilla is a more technical program that has commitment and transfer logs, and clearly nothing but information. It is especially a hit with web developers who require complete control over file transfers via FTP. But it’s the user interface that a lot of people think is overkill, perhaps with explanations on the screen when we potentially don’t need to see them yet.
Cyberduck, however, emphasizes simplicity while not skimping on features. Its polished, easy-to-use interface and no-nonsense feature set make it one of the best gallery apps on Android.
Performance Comparison
FileZilla usually better manages multiple simultaneous transfers, which is great if you need to get hundreds of files over. It’s more of a usability-oriented tool with better GUI integration with cloud services and better visual feedback while transferring files.
Cyberduck installs out of the box with support for the most common cloud providers, while FileZilla needs to be set up for cloud access. This means Cyberduck is our winner for those who predominantly work with cloud storage.
User Experience Differences
Cyberduck for Mac users particularly appreciate the native macOS integration, including Spotlight search support and Keychain password management. Cyberduck for Windows maintains the same clean interface while adapting to Windows conventions.
Advanced features such as directory comparison and synchronized browsing are FileZilla’s forte. Unfortunately, these are underutilized features by most casual users who just want files to transfer reliably.
How to Use Cyberduck for Cloud Storage Like a Pro
Mastering Cyberduck cloud storage integration opens up possibilities that most users never discover. The software excels at treating different cloud services as if they were local folders on your computer.
Amazon S3 Integration
Connecting Cyberduck to Amazon S3 transforms how you manage cloud storage. Instead of navigating through web interfaces, you can drag and drop files directly to S3 buckets. This approach saves significant time when managing large file collections.
The Cyberduck setup for S3 requires only your access key and secret key. Once connected, you can:
- Create and manage buckets with simple right-clicks
- Set custom metadata for uploaded files
- Configure storage classes for cost optimization
- Monitor transfer progress with detailed feedback
Google Drive Integration
Google Drive support in Cyberduck using OAuth authentication, so you don’t need to store your password for Google. It’s this connection that lets you use Google Drive as a network drive, ideal for bulk uploads and downloads that might slip up when executed from the web interface.
Most users find that transferring files from one cloud service to another is a breeze with Cyberduck. You only have to drag your “cloud” bookmark containing some files and drop it into your “cloud” bookmark from another website: the program will do the rest behind the scenes!
Advanced Cloud Workflows
Professional and enterprise users use Cyberduck to work with open cloud storage services, including Amazon S3 and Google Cloud Storage. The utilities can be used with other programs, but they’re intended for use with OpenSSH and other SSH1 and SSH2 clients.
The software’s main features include full SSH protocol working via SSH Tunnel (http, ftp) or your service, and it can help you forward all your requests in connection to a network. Save time by – no details to enter – no passwords to remember – not even your network.
Is Cyberduck Safe? 2025 Security Breakdown
Is it safe to use Cyberduck for file transfers? This problem is number 1 in the heads of security-aware users. The solution will require knowledge of the software’s security settings and best practices for secure file transfer.
Cyberduck supports standard encryption , including TLS 1.3, with the modern cipher suites. All transmitted data is transferred using an encrypted format, so there’s no need to worry about personal information being intercepted.
The application saves connection credentials in the secure keychain or credential manager (in the case of macOS and Windows, respectively), without ever using plain text files to store passwords. This method lowers the risk of credentials theft substantially.
Security Features Overview
Cyberduck provides several security advantages over web-based file transfer methods:
- Local credential storage prevents passwords from being exposed through browser vulnerabilities
- Certificate verification ensures you’re connecting to legitimate servers
- SSH key support offers stronger authentication than traditional passwords
- Connection encryption protects all data in transit
Security Best Practices
To maximize security when using Cyberduck, follow these guidelines:
Enable two-factor authentication on all connected cloud services. Cyberduck supports 2FA tokens, adding an extra security layer to your connections.
Regular software updates ensure you have the latest security patches. The development team actively addresses vulnerabilities and releases updates frequently.
Use SSH keys instead of passwords when connecting to servers. Cyberduck makes SSH key management straightforward, even for non-technical users.
