General 

What is Cyberduck?

Cyberduck is an open-source server and cloud storage browser for Mac and Windows with support for FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive, and Dropbox licensed under the GPL.

Is Cyberduck Free?

Cyberduck is free software. Free software is a matter of the users’ freedom to run, copy, distribute, study, change, and improve the software. If you find this program useful, please consider making a donation. A donation would not only demonstrate your appreciation of this software but also help to advance development in the future. You receive a registration key and it will help to make Cyberduck even better!

What payment options are available?

Donations can be made by using PayPal or Credit card. Alternatively, you can purchase Cyberduck via App Store.

Mac App Store

The presence of Cyberduck is important for the visibility of the project in particular for new and average users on the Mac platform. The caveat is that the donation key model is not supported in the App Store per the developer agreement. Software asking for voluntary contributions does not get approved. We have therefore opted to distribute Cyberduck in the App Store for a fixed price with no donation prompt. It is your choice to buy the version from the App Store or download from the website and opt in for a payment if you feel like. Cyberduck is libre (FLOSS) software and will remain so in the future.

Your purchase receipt from the App Store version is copied to the Application Support folder and recognized as a key when running any version of Cyberduck.

Windows App Store

The Windows Store does not support the donation key model. We have therefore opted to distribute Cyberduck in the Windows Store for a fixed price with no donation prompt. It is your choice to buy the version from the Windows Store or download from the website and opt-in for a payment if you feel like. Cyberduck is libre (FLOSS) software and will remain so in the future.

Troubleshooting

If you bought Cyberduck on Windows Store, but you are not allowed to use Cyberduck due to a Trial Expired error message, please execute the following steps to ensure that your local app license cache is up-to-date – a reinstall of Cyberduck via Windows Store does not refresh your license.

Press the Windows Key + R which opens the “Run” function.
Type in “WSReset” and press enter
Open the Windows Store
Select the user icon (top right)
Select the very top option (where the user profile picture is listed)
Select the account
Select Sign Out
Select the user icon (top right)
Select Sign In

If these steps are not resolving the trial expired message please follow these additional steps to ensure all packages are registered correctly.

Open Start, type PowerShell and open it as Administrator (Ctrl+Shift+Enter, Right-click “Run as Administrator”)
Copy Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Paste it into the window
Run it and wait for completion.

What are the System requirements for Cyberduck?

The system requirements are listed in the installation section.

Can I install older version if necessary?

The recent release can be found on our website. In case your operating system requires an older version of Cyberduck you can download installers for previous versions in our changelog.

Registration Keys 

As a contributor to Cyberduck, you receive a registration key that disables the donation prompt that is displayed when quitting Cyberduck.

Recover a Registration Key 

Registration keys can be recovered using the email address you registered within the donation process.

No Registration Key Received 

A key is sent when the payment is no more pending.
Verify that your email address registered with PayPal is still valid.
Check the spam folder of your email application.

The Registration Key Received Cannot be Opened 

The registration key is sent to you by email automatically after the Paypal transaction has been completed. Make sure the filename of the registration key ends with .cyberducklicense. Some email applications change the extension to .xml when saving the attachment. If the key is invalid, the file must have been modified when saving it from your email application. Try the following:

If you are using a webmail provider, try using a different browser or email client application to access your mail.
Contact you hosting service provider how to download attachments.
Forward the mail to a different mail account where you possibly don’t have an issue downloading attachments.
