Cyberduck is an open-source file transfer and cloud storage client for connecting to FTP servers, SFTP hosts, WebDAV services, and major cloud providers.
Cyberduck is a desktop client for browsing remote servers and cloud storage through one graphical interface. It connects to FTP, FTPS, SFTP, and WebDAV servers, alongside services such as Amazon S3, Microsoft Azure, Google Drive, Dropbox, OneDrive, Backblaze B2, and OpenStack Swift. Website administrators can upload files without relying on command-line tools, while cloud users can organize objects across different providers from a familiar file browser. Bookmarks keep frequently used connections accessible, and saved credentials reduce repetitive setup. The application focuses on direct file management rather than maintaining a continuously synchronized local copy of every remote folder.
Cyberduck supports practical transfer workflows with queued operations, resumable downloads and uploads, folder synchronization, and configurable bandwidth limits. Files can be opened in an external editor, then uploaded after changes, which helps developers update remote content without a separate manual transfer step. Its interoperability across protocols makes it useful when one project combines a traditional server with object storage or a hosted drive. Mozilla Thunderbird handles email and calendars, while this related desktop tool concentrates on moving and managing files across remote services. Connections still depend on valid provider credentials, network availability, and any permissions or transfer limits imposed by the destination.
The main benefit of Cyberduck is that it reduces the effort required to manage files spread across servers and cloud accounts. A consistent browser-based workflow means users do not need a separate client for each supported protocol or storage provider. Saved bookmarks speed up repeat connections, while transfer queues make batches easier to review and control. Resumable operations can prevent a disrupted network session from forcing a large upload or download to restart. Synchronization helps reconcile local and remote folders when maintaining websites, backups, or shared project assets. External editor integration shortens the path from opening a remote file to publishing the revised copy. Support for Cryptomator vaults also gives users an option for client-side encryption when working with compatible cloud storage. Because Cyberduck runs on Windows and works with widely used standards, it can fit mixed hosting environments without locking routine file operations to a single vendor.
Cyberduck connects to FTP, FTPS, SFTP, and WebDAV endpoints from a common interface. Users can browse directories, rename items, adjust permissions where supported, and transfer files without learning separate command syntax for each server type. This flexibility is useful for maintaining websites and administering storage across different hosting environments.
The client works with services including Amazon S3, Microsoft Azure, Google Drive, Dropbox, OneDrive, Backblaze B2, and OpenStack Swift. Users can manage conventional server files and cloud objects in the same application, reducing the need to install provider-specific desktop tools for occasional uploads, downloads, or folder maintenance.
Connection bookmarks store server addresses, protocols, usernames, paths, and other frequently reused settings. Organizing destinations as bookmarks makes recurring administration faster and reduces errors caused by repeatedly entering connection details. Bookmarks are especially helpful for users responsible for several websites, storage buckets, or client environments.
Uploads and downloads appear in a transfer queue that shows progress and lets users manage multiple operations. Interrupted transfers can be resumed when the remote service supports that behavior, saving time on large files. Configurable transfer settings also help users balance network use against other work running on the same connection.
Folder synchronization compares local and remote locations before transferring changed content. This supports website deployment, archive maintenance, and other workflows where two directory trees need to remain aligned. Users can review the proposed actions, which provides more control than blindly replacing an entire destination whenever a few files change.
Remote documents can be opened with a selected desktop editor and transferred back after modification. This shortens the workflow for changing configuration files, web assets, or text documents stored on a server. It also lets users keep working with their preferred editor instead of relying on a limited built-in editing environment.
Integrated Cryptomator support allows compatible encrypted vaults to be accessed within the file browser. Client-side encryption can protect filenames and file contents before data reaches a cloud provider. This gives privacy-conscious users additional control over sensitive material while preserving a practical graphical workflow for routine storage operations.
Cyberduck can generate or copy accessible links for files on supported storage services and servers. This helps users send collaborators a direct location without manually constructing a provider-specific address. Availability and permissions still depend on the destination service, so users retain responsibility for confirming that each shared object has appropriate access settings.
Cyberduck is used to upload, download, browse, and manage files on remote servers and cloud storage. It provides a graphical interface for protocols such as FTP, FTPS, SFTP, and WebDAV, plus connections to several major cloud providers.
Yes. The software is distributed under the GNU General Public License version 3. The project accepts donations, but its open-source license permits users to run, study, modify, and redistribute the covered software under the license terms.
Supported services include Amazon S3, Microsoft Azure, Google Drive, Dropbox, OneDrive, Backblaze B2, and OpenStack Swift. Exact capabilities can vary because each provider exposes different permissions, sharing options, and object-storage behavior.
Yes. The synchronization function compares a local folder with a remote directory and prepares the transfers needed to align them. Users should review the proposed operations before proceeding, particularly when either location contains files that must not be overwritten.
Yes. It supports encrypted connection methods including SFTP and FTPS, subject to the remote server's configuration. It can also work with Cryptomator vaults for client-side encryption on compatible storage services.
Cyberduck can resume interrupted uploads or downloads when the selected protocol and remote service support resuming. This is particularly useful for large transfers, although server policies or changed remote files may sometimes require starting again.
