Wasabi Client: Desktop Tools for Hot Cloud Storage

Wasabi Hot Cloud Storage is S3-compatible with a flat price and no egress bill, which makes it a natural target for a desktop file manager. What Wasabi ships itself is less obvious than it looks, and two of its billing rules quietly decide which kind of client is a good idea. Everything here was read on wasabi.com and docs.wasabi.com in September 2026. For the wider category, see the S3 GUI client overview.

Wasabi does ship a client, and it is someone else's

Three downloads carry Wasabi's name on its own downloads page:

• Wasabi Explorer for Windows — "This free app lets you share files between your Windows host and your Wasabi storage account."
• Wasabi Explorer for Mac — the same sentence with "Mac" in it.
• Wasabi Cloud NAS for Windows — "This paid app lets you replicate file data from your Windows Servers and external NAS appliances to your Wasabi Cloud NAS storage account."

The fact worth knowing before you download: Wasabi's own documentation describes Wasabi Explorer as a customised version of CloudBerry Explorer — the product now published as MSP360 Explorer. So Wasabi's first-party client is a rebadged third-party file manager, which explains its feature list (compression and encryption, multiple regions in one window, upload rules, header editing, multipart upload) and its shape, "a familiar interface similar to Windows File Explorer". The line dates back to 3 April 2018, when Wasabi announced a free Hot Cloud Storage Client for Mac and Windows with drag-and-drop virtual drives, one of them write-once.

Wasabi Cloud NAS is a different animal and should not be mistaken for a browser. It is cloud-gateway software installed on a Windows server or PC that tiers cold files off local storage into a bucket and leaves stubs behind, with a shell extension that adds data-management commands to Windows Explorer's context menu. Useful; not a way to look at a bucket.

Wasabi is also unusually candid about the limits of its own app. Its downloads page says the third-party tools it recommends "generally provide more features than Wasabi Explorer, including the ability to mount Wasabi Hot Cloud Storage as a disk volume on your Windows or Mac host", and names four: MSP360 Drive, Cyberduck, ExpanDrive and Mountain Duck.

The one setting that matters: the regional service URL

Any S3 client reaches Wasabi by changing the endpoint — in Wasabi's words, "The AWS SDKs or tools can be used directly with Wasabi by changing the endpoint." Each region has its own service URL, and using the wrong one is the most common cause of a bucket that "does not exist".

Note the asymmetry: us-east-1 is the bare s3.wasabisys.com with no region in the hostname, every other region carries its code. Wasabi's API documentation lists the supported HTTP methods as PUT, GET, DELETE, POST and PATCH, and does not document a path-style requirement — so treat any "force path style" toggle as not documented rather than required, and leave it off unless a listing fails.

aws s3 ls --endpoint-url https://s3.eu-central-1.wasabisys.com
rclone config create wasabi s3 provider Wasabi endpoint s3.eu-central-1.wasabisys.com

Credentials are an access key and secret key from the Wasabi console, and a client can do exactly what that key can do — so scope it to the bucket and prefix you mean, not to everything.

Two billing rules that decide which client you want

Wasabi's pay-as-you-go price starts at $7.99 per TB per month with "No fees for egress or API requests". That last part is the reason a GUI client feels free here and expensive on Amazon: browsing, listing and previewing all cost API calls, and on Wasabi those calls are not billed.

The two rules that bite are on the other side:

1. A 90-day minimum storage duration. Delete an object before it has been stored 90 days and a Timed Deleted Storage charge equal to the storage charge for the remaining days applies.
2. A 1 TB monthly minimum. Store less than 1 TB of active storage and you are still billed for 1 TB at your region's rate.

Read those together and a conclusion falls out: a client that constantly rewrites or rotates objects — an aggressive sync tool, a backup job with a short retention, a build cache — is buying 90 days of storage for every file it replaces. On Wasabi, a browser you use deliberately is cheaper than a syncer you forget about. That is an argument for a file manager, and against anything that mirrors a folder continuously.

The field, September 2026

The shape of that table is the answer to most Wasabi client searches. If you want a free window and nothing else, Cyberduck or Wasabi Explorer. If you want a drive letter, everything free on the list needs either a kernel driver (rclone plus FUSE or WinFsp) or a paid licence — except the WebDAV route below. The Cyberduck alternatives and Mountain Duck alternatives pages compare those two in depth, and cloud storage manager covers the ten-product field.

Reaching Wasabi from AnyStorage

Wasabi is not a separate connection type in AnyStorage 0.2.25 — it is the S3 type with a custom endpoint URL, which is exactly what Wasabi's own documentation asks of any S3 tool. Paste the service URL for your region, the access key pair and the region string, leave path-style off unless a listing fails, and the buckets open as folders. Cloudflare R2, Backblaze B2, Google Cloud Storage, Azure Blob, Alibaba Cloud OSS and Tencent Cloud COS do get their own types, out of more than 20 including WebDAV, FTP, SFTP, Google Drive, OneDrive and Dropbox, so a Wasabi bucket can sit beside a Drive account in one window.

Mounting is where it diverges from the recommended four. Instead of a filesystem driver, the app runs a WebDAV server on http://127.0.0.1:3211 with HTTP Basic auth always on, and your operating system's own WebDAV client mounts it — Finder, File Explorer, GNOME Files, Dolphin or davfs2. No macFUSE, no WinFsp, no reduced-security boot on Apple silicon. The detailed walkthrough is on map an S3 bucket as a network drive, and platform specifics are on the Windows and Mac pages.

The limits, stated plainly: the free tier allows two storage connections and serves that mount read-only, so a writable drive is a paid feature; 0.2.25 is a young product; and there is no CLI. What the free tier does allow is commercial use.
