Cyberduck Alternatives in 2026: Seven Compared

Where Cyberduck stops being enough

Updated 24 September 2026. Cyberduck is the default recommendation in this category, and mostly it deserves to be. Version 9.5.4 shipped on 25 August 2026, it is licensed under the GPL, it costs nothing to download, and one window speaks FTP, SFTP, WebDAV, SMB, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure, OneDrive, Google Drive and Dropbox. Very little free software covers that much ground.

People still look for an alternative, and in practice they are looking for one of four specific things.

• A Linux build. Cyberduck's download page lists Windows 10 (64-bit) or later, and macOS 10.13 or later on Intel or Apple M1. There is no Linux desktop build. Flathub has no ch.iterate.cyberduck application as of September 2026, while it does carry FileZilla under GPL-2.0-or-later. The duck command-line tool does run on Linux, but a CLI is not the window you were using.
• Mounting. Cyberduck browses and transfers. Making remote storage behave like a disk is the job of its paid sibling Mountain Duck, or of one of the mount tools below.
• The donation prompt. In Cyberduck's own words: "As a contributor (minimum amount 10 USD) you receive a registration key that registers the installed application to your name and disables the donation prompt." That is a fair deal, and it is also a recurring interruption on a work machine.
• Modern object storage as its own connection type. Cyberduck's front page lists Amazon S3 and OpenStack Swift among its providers; Cloudflare R2 is not among them. R2 speaks the S3 API, so it works through a custom endpoint, but you will be assembling that yourself.

If none of those four is your problem, stay where you are. Cyberduck is free, mature and actively released, and this page is not going to pretend otherwise.

The seven alternatives, side by side

Two columns in that table do most of the work. Linux build eliminates four of the seven, which is why "Cyberduck alternative for Linux" is a much narrower question than it looks. Mounts as a drive splits the rest into two different products wearing similar screenshots: a file browser you look at, and a virtual disk your other applications write into.

AnyStorage: a workspace first, a mount second

This is the app this site makes, so the argument here is a list of facts rather than a list of adjectives. Release 0.2.25 shipped on 23 September 2026 for all three desktops: macOS 11 or newer as signed .dmg builds for Apple silicon and Intel, installable with brew install --cask kilerd/tap/anystorage; Windows 10 or newer as an NSIS installer and an .msi; and Linux as an amd64 AppImage or a .deb for Ubuntu 20.04 and later.

The default shape is a file workspace, which is the part of Cyberduck people actually like: buckets and remote folders in tabs, one transfer area with progress and history, credentials stored encrypted on the machine, no account to create. Mounting is there when you want it and it does not install a filesystem driver. The app runs a WebDAV server on http://127.0.0.1:3211 and Finder, File Explorer, GNOME Files, Dolphin or davfs2 mounts that. No macFUSE, no WinFsp, no reduced-security boot on Apple silicon. More than 20 connection types are supported, with Cloudflare R2, Backblaze B2, Google Cloud Storage, Azure Blob, Alibaba Cloud OSS and Tencent Cloud COS as their own types rather than S3 with a hand-written endpoint; MinIO and Wasabi do use the S3 type with an endpoint URL and path-style addressing. The free tier allows two connections, permits commercial use and serves WebDAV read-only. Pro removes the connection limit, makes the WebDAV server read-write and adds search, preview, bulk operations and drag-and-drop upload.

The concrete limitation: the free tier stops at two connections, which is fewer than Cyberduck's unlimited bookmarks. There is also no offline sync, no command line, no TLS on the local WebDAV server in the current version — which is exactly why it binds to loopback — and no arm64 Linux build. If you want a closer look at either end of the platform range, there are dedicated pages for the Linux S3 client and the macOS S3 client.

Mountain Duck: the Cyberduck you mount

Mountain Duck is made by the same people as Cyberduck, which makes it the least surprising migration on this list. It is paid software for macOS 13 or later and Windows 10 or later; version 5.3.2.29785 is dated 25 August 2026, the same week as Cyberduck 9.5.4. Its entire job is making remote storage look mounted, and version 5 does it through the operating system's own sync APIs: in its words, "the new Integrated connect mode syncing with File Provider (macOS) and Cloud Files (Windows) APIs. No device driver installation or network mount required." Installation needs no admin privileges.

Licensing is per seat and per major version: one key covers any number of computers as long as it is the same person using them, and a major upgrade is a discounted repurchase rather than an entitlement. Protocol coverage is inherited from Cyberduck — FTP, SFTP, WebDAV, SMB, Nextcloud and ownCloud, Amazon S3, Google Storage, OpenStack Swift, Azure, OneDrive, SharePoint, Dropbox, Google Drive, Box, Wasabi, Backblaze B2 and the local filesystem — and most of its technical documentation lives on cyberduck.io rather than on its own five-page marketing site.

The concrete limitation: no Linux build, and no published price you can read before you start a purchase. The store page asks for a user count and a currency and then computes the total, so a straight comparison against a $45 or $74 competitor is not something the site will let you do at a glance. If Mountain Duck rather than Cyberduck is your actual starting point, the Mountain Duck alternatives page compares it against the same field.

CloudMounter: the mount tool with the strangest price list

CloudMounter, from Electronic Team, mounts cloud services and remote servers as drives. Version 4.18 for macOS was released on 18 June 2026 and needs macOS 12.4 or later; version 3.8.2156 for Windows was released on 16 September 2026 and supports Windows 7 SP1 through Windows 11. On macOS it connects Dropbox, OneDrive, Amazon S3, Google Drive, WebDAV, SFTP, FTP, pCloud, Box, Backblaze, MEGA and OpenStack; the Windows build drops pCloud, Backblaze and OpenStack from that list.

The pricing is worth reading twice, because it is the one fact about CloudMounter that almost nobody writes down. On macOS, a Personal licence for one Mac is $74 as a lifetime purchase or $29 a year as a subscription, and both are marked "personal use only"; a Team licence for five Macs is $249 lifetime or $99 a year and allows business use. On Windows the same product is a plain one-time purchase: $29.99 for one PC, $99.99 for five. So a perpetual Windows licence costs roughly what a single year of the macOS subscription costs, and the vendor's own FAQ confirms the asymmetry: "Currently, the Windows version is sold as a one-time purchase, while macOS offers both."

The concrete limitation: there is no Linux build, and the free mode is Windows-only and deliberately thin — after the 14-day Pro trial, the free version gives full access to one Google Drive, Dropbox or OneDrive account while "additional accounts and services are read-only." If free is the actual requirement, the free CloudMounter alternatives page starts from that constraint instead.

ExpanDrive: the one that is actually free, with a caveat

ExpanDrive is the awkward entry on every list like this, because it stopped being a paid product. Files.com acquired it in January 2024 and relaunched it in April 2025 as free for personal use — the announcement's own phrasing is "every cloud service, every operating system, no trial timer, no degraded free tier. Forever." That covers solo users, households, freelancers and teams up to ten people, on macOS, Windows and Linux, with signed installers for each. Past ten users you move to a Business plan at "a flat $29/month for the whole team," which adds Server Edition, a web management console and priority support.

For a Cyberduck user this is the closest thing to a free upgrade in the category, and besides AnyStorage and rclone it is the only tool here with a real Linux build. Its integration list runs Amazon S3, Backblaze B2, Box, Dropbox, FTP, Google Cloud Storage, Google Drive, IDrive e2, Nextcloud, OneDrive, OneDrive for Business, SFTP, SharePoint, Wasabi and WebDAV.

The concrete limitation: it is a mount, not a workspace — there is no bucket window with a visible transfer queue in the sense Cyberduck gives you — and it is now a client owned by a storage vendor, with an "Upgrading to Files.com" page in the site navigation. That is a legitimate business and it is also a reason some teams prefer a client with no service behind it. Cloudflare R2 is not in the integration list. There is a longer treatment on the ExpanDrive alternatives page.

Transmit 5: the macOS answer, if money is not the question

Transmit is Panic's file transfer app, and on macOS it is the most polished thing in this comparison. It costs $45 once — "try Transmit for 7 days — for free. Keep it forever for only $45" — and requires macOS 13.0 or later. It handles FTP, SFTP, WebDAV and S3, plus Backblaze B2, Box, Google Drive, Microsoft Azure, Rackspace Cloud Files, Dropbox, OneDrive for Business, DreamObjects, OpenStack Swift and Amazon GovCloud S3. Panic Sync keeps saved servers in step across Macs, and File Sync handles local-to-local and remote-to-remote work.

For a designer or developer who lives on a Mac and wants the best-feeling browser in the category, this is the straight swap for Cyberduck: same job, better execution, one payment instead of a donation prompt.

The concrete limitation: macOS only, and mounting is not advertised on Panic's Transmit 5 page as of September 2026 — the page describes transfers, sync and speed, not a virtual disk. If the reason you are leaving Cyberduck is that you want a drive letter, this is not the tool. The Transmit alternatives for Mac page covers the reverse direction.

rclone: free, universal, and not a window

rclone is the tool every other entry here is implicitly measured against. It is free under the MIT licence, runs on Linux, Windows, macOS and FreeBSD, and "over 70 cloud storage products support rclone" — including Cloudflare R2, which several of the commercial tools on this page still do not list. rclone mount gives you the drive behaviour on all four platforms.

If your work is sync jobs, cron entries and repeatable copies, nothing on this page competes with it, and it is the right answer for servers where a GUI makes no sense at all.

The concrete limitation: the mount needs a kernel-level helper and careful flags. The documentation is explicit — "to run rclone mount on Windows, you will need to download and install WinFsp" — and on cache behaviour it warns that "without the use of --vfs-cache-mode this can only write files sequentially, it can only seek when reading. This means that many applications won't work with their files on an rclone mount without --vfs-cache-mode writes or --vfs-cache-mode full." That is a tuning exercise, not a checkbox, and the official web GUI is still described as experimental. See rclone mount alternatives if that is the specific part you want to replace.

WinSCP: the free Windows workhorse

WinSCP is free software under the GPL, it has been maintained by Martin Přikryl since 2000, and its own tagline is precise about scope: "Free SFTP, SCP, S3 and FTP client for Windows." It supports FTP, FTPS, SCP, SFTP, WebDAV and S3, it has scripting and a .NET assembly, and in a Windows shop it is often already installed and already approved.

If you are on Windows, your work is SFTP and FTP with occasional S3, and you want zero licensing conversations, WinSCP replaces Cyberduck completely and costs nothing.

The concrete limitation: Windows only, and it does not mount. It is a two-pane transfer client, not a virtual disk, and its object-storage support is narrower than a dedicated S3 tool's. FileZilla Pro is the other paid option in this corner — it runs on Windows, macOS and Debian-based Linux, starts at €12.99 for a single device, and adds Amazon S3, Backblaze B2, Box, Dropbox, Google Cloud, Google Drive, Microsoft Azure, OneDrive, SharePoint, OpenStack Swift and WebDAV to the free FileZilla client, which by the project's own description "supports FTP, FTPS, and SFTP." The Cyberduck vs FileZilla comparison takes that pair apart properly.

Pick by need

• You need Linux with a graphical interface. AnyStorage, ExpanDrive or rclone. The other four do not ship a Linux build at all, and that single fact decides most of these searches.
• You want a free window for buckets and servers. Stay on Cyberduck, or use WinSCP on Windows. Neither costs anything and neither will surprise you.
• You want remote storage to appear as a disk without installing a driver. AnyStorage or Mountain Duck. AnyStorage does it with a loopback WebDAV server, Mountain Duck with the operating system's sync APIs.
• You want a drive and you are one person on macOS or Windows. ExpanDrive's free tier is very hard to argue against.
• You are on macOS and want the nicest app. Transmit 5, $45, one payment.
• You script more than you click. rclone, with a GUI beside it for the occasional look.
• Your storage is Cloudflare R2, Alibaba Cloud OSS or Tencent Cloud COS. AnyStorage or rclone. The rest either omit these from their integration lists or expect you to configure a generic S3 endpoint by hand. There is more detail on the S3 GUI client page.
