Cyberduck for Linux: your options in 2026
Last updated October 23, 2026 · By the BucketWorx team. We're building BucketWorx, a desktop S3 client that isn't released yet. It's mentioned below, but it isn't ranked or scored against the apps you can use today.
Where Cyberduck stands on Linux
Cyberduck 9.5.4 (August 25, 2026) runs on macOS 10.13 or later and 64-bit Windows 10 or later. Its download page mentions Linux only for the command-line interface.
People have asked for a Linux version since July 2011. ThatGitHub issue is still open, and was renamed "Graphical Interface for Linux" in October 2025 because the CLI already runs on Linux. In 2011 and 2013 the developers said they had no plans for one, citing a lack of resources. That changed in October 2026, as described below.
Mountain Duck, from the same developers, runs on macOS and Windows only.
Option 1: the official Cyberduck CLI (duck)
duck is the official Cyberduck command-line tool, from the same developers and built on the same core. It lists, uploads, downloads and syncs files, and can open a remote file in a local editor and upload it when you save. It covers the protocols you'd expect: FTP, FTPS, SFTP, WebDAV, SMB, Amazon S3 and S3-compatible storage, Backblaze B2, Azure, Google Cloud Storage, Google Drive, OneDrive, Dropbox and more.
The CLI docs list an apt repository for Debian and Ubuntu, an RPM repository, a Docker image (ghcr.io/iterate-ch/cyberduck) and a third-party AUR package for Arch. The docs warn that another, unrelated Debian package is also called duck, so check which one you're installing.
Best for: scripts, servers, and anyone who already knows Cyberduck and is fine in a terminal.
Option 2: the unofficial "Cyberduck for Linux" build
On October 11, 2026, a developer (leancode on GitHub) posted a working Linux desktop app for Cyberduck on the long-running issue. It's a fork,leancode/cyberduck-linux, that adds a JavaFX interface on top of Cyberduck's shared core, the same way the macOS and Windows apps sit on it. Releases come as .deb and .rpm packages for x64 and arm64, with a checksum file. The latest is 9.6.0.45959, from October 14, 2026.
The author lists browsing, bookmarks, Quick Connect, uploads, downloads and sync, drag and drop, editing in an external editor, Cryptomator vaults and OAuth logins as working. Bookmarks and profiles are shared withduck.
Before you rely on it, know where it stands:
- It isn't official. The packages are labelled "Cyberduck for Linux (unofficial)". A Cyberduck maintainer replied that they "should definitely get this ready to be merged upstream", but also that there's "still a ton of work to reach feature parity" with macOS and Windows.
- Testing is limited so far. Automated tests cover SFTP and HTTPS, and the author has used it by hand against an SFTP server. Other protocols, including S3, haven't been walked through by hand yet, and neither have Wayland or HiDPI screens.
Best for: Cyberduck users who want the familiar app on Linux and are happy to test early software.
If you used Cyberduck for SFTP or FTP
Many people search for Cyberduck on Linux because they want a friendly SFTP or FTP client. Linux covers this well already:
- FileZilla is free, open source, and handles FTP, FTPS and SFTP on Linux. Most distributions package it.
- Your file manager may be enough. GNOME Files, for example, connects to SSH, FTP, WebDAV, SMB and NFS servers from Other Locations, with no extra software. It doesn't do S3.
If you used Cyberduck for S3 and cloud storage
This is where Linux has fewer desktop apps. The options:
rclone: every provider, scriptable, with a basic web GUI
rclone is free and MIT-licensed, and supports more providers than anything else here, including Amazon S3, Cloudflare R2, Backblaze B2, Wasabi and MinIO, plus SFTP and FTP. It syncs, copies and mounts buckets as folders. rclone gui opens a web interface in your browser with explorer, remotes and mounts views, but the terminal has to stay open while you use it, and most work still happens on the command line.
Best for: power users, servers and automation.
ExpanDrive: buckets as a drive, with a desktop app
ExpanDrive mounts S3, Backblaze B2, Wasabi, SFTP, FTP, WebDAV and other services as drives. It ships.deb, .rpm and AppImage packages for 64-bit x86 Linux. It's free for personal use and for teams of up to 10 users, commercial use included, with no trial timer. Past 10 users in a year, Business is a flat $29 a month for the whole team. Its download page doesn't mention Cloudflare R2 or ARM Linux.
Best for: working on bucket files from your editor or other desktop apps.
FileZilla Pro: FileZilla plus cloud storage
FileZilla Pro adds Amazon S3 and S3-compatible endpoints, Cloudflare R2, Backblaze B2 and other cloud services to FileZilla. On Linux it officially supports Debian, and works unofficially on Ubuntu and other Debian-based distributions. It's a subscription, from €12.99 a year for one device.
Best for: FileZilla users who also need S3, and are on Debian or Ubuntu.
Mountpoint for Amazon S3 and s3fs: mount without a GUI
Mountpoint for Amazon S3 is AWS's open-source (Apache 2.0) tool for mounting a bucket as a folder on Linux, for x86_64 and arm64. It's built for reading large files and writing new ones. It can't edit existing files or rename directories, and AWS doesn't support it for other S3-compatible services.
s3fs (GPL v2) is older and works with S3-compatible providers through a custom endpoint. Editing part of a file re-uploads the whole object, and renames aren't atomic.
Best for: servers and pipelines that need a bucket to look like a folder.
