Mac and iPhone
Mount Cloudflare R2, Amazon S3, Backblaze B2 or any S3-compatible bucket as a drive in Finder and a location in the iPhone Files app. Built for macOS 26 and iOS 26.
Your keys stay in your device Keychain. There is no Allmount server.
Mac Pro plan
Your bucket sits in the Finder sidebar next to your other disks. Files download only when you open them. A 4 GB video starts playing in seconds because Allmount fetches only the bytes the player asks for.
iPhone Included in Free
Allmount adds a location to the Files app, so any app that opens files can open yours. Save into a bucket from any Files picker. On iPhone a file downloads in full when you open it.
Menu bar Pro plan
Drag a file onto the Allmount icon and it uploads to your current connection, with progress in the popover. When it lands, copy a link that expires after 1 hour, 1 day or 7 days.
Uploads
Files over 64 MB go up in parts. If the connection drops or the lid closes, retry and Allmount picks up from the last finished part instead of starting over. Every file in the queue has its own progress and cancel.
Privacy
Access keys go into the Keychain on your Mac or iPhone, stored device-only. There is no Allmount account and no Allmount server. The app sends no analytics. Files move straight between your device and your bucket.
Keep R2 for delivery, B2 for archive and MinIO at home, each with its own keys.
Buckets in Cloudflare's EU or FedRAMP jurisdiction connect to the right endpoint.
Point a custom endpoint at your NAS, and plain http works on your local network.
Press Space to preview a file before you open it.
Search the current folder and sort by name, size, date or kind.
See object count, total size, a breakdown by file type and your recent uploads.
Compared
You already have two ways to reach a bucket. Here is how they stack up for daily use.
| Allmount | A web console | A sync folder app | |
|---|---|---|---|
| Disk space used | None until you open a file (Mac) | None, you download files by hand | Often a local copy of what you sync |
| Works in Finder | Yes, as a drive (Pro) | No, it lives in a browser tab | Yes |
| Works in iPhone Files | Yes, on the free tier | No | Depends on the app |
| Streams video | Yes on Mac, by byte range. iPhone downloads first. | Download first, unless the console has a preview | Usually downloads the whole file first |
| Needs an account | No Allmount account. Your provider keys only. | Your provider login | Usually an account with the app's own service |
Web consoles and sync apps vary. This table describes the common case, not any one product.
Why we built this
We keep our files in object storage because it is cheap and we control the bucket. Getting at them was the annoying part. Every time, we opened a web console, clicked through folders and downloaded a file just to look at it. Sync apps wanted to copy the whole bucket to disk or route things through their own account.
We wanted the bucket to act like a disk in Finder and show up in Files on the phone. So we built Allmount.

Prices in US dollars. The App Store charges your local currency, like rupees in India. One purchase covers Mac and iPhone, and Family Sharing is included. Purchases and refunds go through Apple. If a subscription lapses, your first connection keeps working and your settings stay put.

No. Files go straight between your device and your bucket. The only other copies are files you open, cached on your own device.
Partly. Files you already opened stay on disk until macOS reclaims the space, so they open without a connection. Anything you have not opened needs one, because Allmount does not copy the bucket to your disk.
Extra connections and the Finder drive pause. Your first connection keeps working on the free tier and your settings stay in place. Subscribe again or buy lifetime and everything comes back without re-entering keys.
Not yet. On iPhone, files download fully when you open them, which is how the Files app works today. Streaming by byte range is a Mac feature in this release.
Cloudflare R2, Amazon S3, Backblaze B2, Wasabi, MinIO, DigitalOcean Spaces, Hetzner, Scaleway, Oracle, Google Cloud Storage through S3 interop, and any custom S3 endpoint. Azure Blob, native Google Cloud Storage, WebDAV, SFTP, Google Drive, Dropbox and OneDrive are planned, no dates yet.
Yes. Add a custom endpoint with your NAS address and port, then paste the keys. Plain http is allowed only on your local network. Use https when your NAS supports it.
Allmount is not on the App Store yet. It will ship as one app for Mac and iPhone.
