What WebDrive actually is
Updated 24 September 2026. WebDrive is a drive-letter client from South River Technologies of Annapolis, Maryland — the same company that sells the Titan SFTP and MFT server line. Its own one-sentence description is the clearest statement of the product: it "maps remote and cloud storage as a secure local drive, giving users seamless access while IT maintains policy control, visibility, and centralized governance."
That last clause is what most comparison pages miss. WebDrive is not sold to the person who wants a bucket in Explorer; it is sold to the IT department that wants that person to have one, under policy, without a VPN.
Platforms are listed as "Windows 10+, Windows Server, macOS" — no Linux build is listed. The services on the product page are "SFTP, FTPS, HTTPS, WebDAV, Amazon S3, Google Drive, SharePoint, Dropbox, Synology", and the knowledge base adds FTP, Google Cloud Storage, IBM Storage, OneDrive for Business and Box.
It is also the mature version of this idea, keeping features the modern crop dropped: a cache for files and directory listings with a configurable disk limit, an Asynchronous Cache Mode for deletes, renames and creates, WebDAV locking, and an offline mode that syncs on reconnect. If your objection to a newer tool was "no cache, no locking", WebDrive answers it.
Why people look for an alternative
Three reasons, all visible on South River's own pages.
- The price, and its shape. The published annual ladder is $150 for an Individual licence, $530 for 10 seats, $1,050 for 25, $1,600 for 50, $2,500 for 100, $4,550 for 250, $5,900 for 500, $7,500 Educational and $15,000 Enterprise, and the model is stated plainly: "WebDrive is an annual renewal and includes Maintenance and Support for the duration of your license term." Several rivals publish no figure at all — but $150 a year for one person is top of category, and it renews.
- No Linux. Windows 10 and later, Windows Server and macOS only.
- Drive letters run out. South River documents this itself: the knowledge base carries an article titled "More than 25 Site Connections: Out of Drive Letters." A product that spends one letter per connection has a ceiling near the size of the alphabet, and at forty client servers the architecture is the problem.
One thing to confirm before planning a pilot: South River's trials page is headlined "20-Day Free Trial" while WebDrive's own licensing documentation describes a 30-day evaluation. The two vendor sources disagree.
The seven alternatives, side by side
| Tool | Platforms | Price model | Mounts as a drive | Protocols and services | Free tier |
|---|---|---|---|---|---|
| WebDrive | Windows 10+, Windows Server, macOS | Annual per seat, $150 to $15,000 | Yes, one letter per connection | SFTP, FTPS, HTTPS, WebDAV, S3, Drive, SharePoint, Synology | None, trial only |
| AnyStorage | macOS 11+, Windows 10+, Linux | Free tier plus paid Pro | Yes, local WebDAV server | 20+ types: S3, R2, B2, MinIO, GCS, Azure Blob, OSS, COS, WebDAV, SFTP | 2 connections, commercial use OK |
| ExpanDrive | macOS, Windows, Linux | Free for personal use and teams of 10, then $29/month | Yes | S3, B2, GCS, Wasabi, IDrive e2, drives, SFTP, WebDAV | Full product, 10 users |
| Mountain Duck | macOS 13+, Windows 10+ | Per seat, per major version, price not published | Yes, File Provider / Cloud Files, no driver | FTP, SFTP, WebDAV, SMB, S3, Swift, Azure, B2, drives | Trial only |
| CloudMounter | macOS 12.4+, Windows 7 SP1+ | macOS $74 lifetime or $29/year; Windows $29.99 once | Yes | S3, WebDAV, SFTP, FTP, drives; Backblaze on macOS only | Windows only, 1 account read-write |
| Cyberduck | macOS 10.13+, Windows 10+ | Free, GPL; $10 key removes the prompt | No, it browses | FTP, SFTP, WebDAV, SMB, S3, Swift, B2, Azure, drives | Everything, permanently |
| rclone | macOS, Windows, Linux, FreeBSD | Free, MIT licence | Yes, needs FUSE or WinFsp | 70+ storage products, R2 included | Everything, permanently |
| RaiDrive | Windows 7 SP2+ GUI, Linux CLI only | Free tier, paid from USD1.84/month on 3 years | Yes, its whole purpose | AWS, Azure, GCP, WebDAV, SFTP, FTP, drives | Standard: 8 drives, ads |
Three columns decide most of these searches. Price model splits the subscriptions from two perpetual licences and four free tools. Mounts as a drive splits a window you look at from a volume other applications save into. Platforms costs WebDrive the Linux half of a mixed fleet.
AnyStorage: a workspace with an optional mount, no driver
This is the app this site makes, so the case is checkable facts with the limitations included. Release 0.2.25 shipped on 23 September 2026 for macOS 11 or newer, Windows 10 or newer and Linux — an amd64 AppImage or a .deb for Ubuntu 20.04 and later, plus brew install --cask kilerd/tap/anystorage. It inverts WebDrive's priorities: the workspace is the product and the mount is a feature. Connections open in tabs, transfers land in one area with progress and history, credentials stay encrypted on the machine.
The mount installs no 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. Every connection open in the app appears as a folder at the WebDAV root, which is the structural answer to the drive-letter ceiling: twenty connections are twenty folders under one mount, not twenty letters. R2, B2, Google Cloud Storage, Azure Blob, Alibaba Cloud OSS and Tencent Cloud COS each get their own connection type rather than a hand-assembled S3 endpoint. The free tier caps you at two connections and serves the mount read-only; Pro removes both limits.
The concrete limitations, three. No offline mode and no file locking, because a loopback WebDAV mount is a live view rather than a cached lockable copy. No policy console and no per-user governance: this is a desktop app a person installs, not a managed client. And 0.2.25 is a young 0.2.x release with no CLI and no arm64 Linux build. See mount cloud storage as a local drive.
ExpanDrive: the closest like-for-like, free below eleven people
The shortest path to WebDrive's behaviour on a smaller budget. ExpanDrive mounts remote storage as a drive on macOS, Windows and Linux, and since April 2025 it is free for personal use. Files.com acquired it in January 2024 and relaunched it with a promise its own announcement states plainly: "every cloud service, every operating system, no trial timer, no degraded free tier. Forever." That covers individuals, freelancers and teams up to ten; past ten users, Business is "a flat $29/month for the whole team." Against the ladder, ten WebDrive seats are $530 a year and ten ExpanDrive seats are nothing.
The concrete limitation: the client is now owned by a storage vendor selling a competing managed service, with "Upgrading to Files.com" in its own navigation, and Cloudflare R2 is not in the integration list. See ExpanDrive alternatives.
Mountain Duck: the most native mount, at an unpublished price
Look here if what you liked about WebDrive was that files behaved like local files. Version 5.3.2.29785 is dated 25 August 2026, needs macOS 13 or later or Windows 10 or later, and installs no filesystem driver: "the new Integrated connect mode syncing with File Provider (macOS) and Cloud Files (Windows) APIs. No device driver installation or network mount required." Both are sync engines with an offline cache, so this is the entry closest to WebDrive's caching behaviour.
The concrete limitation: no Linux build, and no price you can read before starting a purchase. Licensing is per seat and tied to one major version, but the store quotes nothing until you pick a user count and a currency — after WebDrive's published ladder, a step backwards. The Mountain Duck alternatives page compares the same field from its side.
CloudMounter: the cheapest perpetual licence on Windows
The tool that undercuts WebDrive hardest on a single machine. 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, Personal for one Mac is $74 lifetime or $29 a year, both marked personal use only; Team for five Macs is $249 lifetime or $99 a year with business use allowed. On Windows it is one-time — $29.99 for one PC — so one machine costs $29.99 once against $150 every year.
The concrete limitation: no Linux build, and the free mode exists only on Windows — after a 14-day Pro trial, "the Free version provides full access to one account for Google Drive, Dropbox, and OneDrive, while additional accounts and services are read-only." The free CloudMounter alternatives page starts there.
Cyberduck: free, and it does not mount
Worth a paragraph because a fair share of people paying for a mount wanted a window. Cyberduck 9.5.4 was released on 25 August 2026, is GPL, and covers FTP, SFTP, WebDAV, SMB, S3, Swift, Backblaze B2, Azure and the three big cloud drives on macOS 10.13 or later and Windows 10 or later. If your work is "open the server, look at the files, move these," it replaces WebDrive for nothing. It does not mount at all, there is no Linux desktop build beyond the duck CLI, and a donation of at least 10 USD removes the prompt. See Cyberduck alternatives.
rclone: free, scriptable, and the most configuration
rclone is free under the MIT licence, runs on Linux, Windows, macOS and FreeBSD, and by its own count "over 70 cloud storage products support rclone".
powershell
rclone mount sftp-remote:/srv/data X: --vfs-cache-mode writes --network-modeThe concrete limitation: the mount is where the time goes. The docs are explicit that "to run rclone mount on Windows, you will need to download and install WinFsp" — a kernel-mode filesystem driver, the class of install the newer tools avoid — and that "many applications won't work with their files on an rclone mount without --vfs-cache-mode writes or --vfs-cache-mode full". On macOS it needs macFUSE or FUSE-T. See rclone mount alternatives and rclone mount FUSE errors.
RaiDrive: the cheapest way to get eight drive letters
The closest thing to WebDrive's mental model at the low end: accounts become drive letters on Windows, and nothing else. RaiDrive Mount GUI 2026.6.25 of 25 June 2026 installs on Windows 11 for x64 and arm64, on Windows 7 SP2, 8.1 and 10, and on Windows Server 2012R2 or later. Its free Standard tier is the most usable free mount here — eight drives at once, write access to Google Drive, OneDrive, Dropbox and the WebDAV, SFTP and FTP protocols, read-only for twenty-odd others — paid for with an advertisement in the app.
The concrete limitation: no macOS build at all, and Linux support is RaiDrive CLI rather than the desktop app. It solves the price objection, not the platform one.
Pick by need
- One person resenting $150 a year: CloudMounter on Windows at $29.99 once, RaiDrive's free tier, or ExpanDrive free if the use is personal.
- Linux machines in the fleet: AnyStorage, ExpanDrive or rclone.
- More than 25 connections: stop spending a letter per connection — see cloud storage manager for tools that present connections as folders.
- Offline files and WebDAV locking: stay on WebDrive, or move to Mountain Duck.
- Central policy and an audit trail: stay on WebDrive. Every alternative here is a desktop app a user installs.
- SFTP servers: mount SFTP as a network drive, or mount SFTP on Windows 11.
- Buckets: mount S3 as a network drive and mount Backblaze B2 as a drive.
Questions
How much does WebDrive cost?
WebDrive publishes an annual per-seat ladder, which is more than most competitors do: as checked in September 2026, $150 a year for one seat, $530 at 10 seats, $2,500 at 100 and $15,000 for Enterprise. The site states that "WebDrive is an annual renewal and includes Maintenance and Support for the duration of your license term", so it is a subscription, not a perpetual licence.
Is there a free WebDrive alternative?
Four, with different trade-offs. ExpanDrive is free for personal use and teams up to ten on all three desktops and does mount. RaiDrive's free Standard tier gives eight drive letters on Windows, with an advertisement in the app. rclone is free under the MIT licence but needs WinFsp or macFUSE. AnyStorage's free tier mounts through a local WebDAV server, capped at two connections, commercial use allowed. Cyberduck is free but does not mount.
Does WebDrive run on Linux?
Not according to South River's own product page, which lists "Windows 10+, Windows Server, macOS". Of the alternatives here, AnyStorage, ExpanDrive and rclone have Linux builds; Mountain Duck and CloudMounter do not, and RaiDrive ships only a CLI. That single fact shortens the list to three.
What happens when I run out of drive letters in WebDrive?
South River documents this case themselves, in a knowledge base article titled "More than 25 Site Connections: Out of Drive Letters". It is the structural cost of a client that spends one letter per connection. A tool that presents every connection as a folder under one mount point avoids the ceiling entirely — that is how AnyStorage's local WebDAV server works, and it is the main architectural difference between the two.
Which WebDrive alternative keeps files available offline?
Mountain Duck is the closest match: version 5 mounts through File Provider on macOS and Cloud Files on Windows, both sync engines with an offline cache. WebDrive's own offline mode and configurable cache remain a genuine differentiator against the rest of this list, because AnyStorage, RaiDrive, CloudMounter and rclone's default mount all present a live view instead.
