Every drive becomes a real folder — Finder opens it, and so does your AI agent. One Mac app for every storage account — cloud object storage, WebDAV/SFTP/FTP servers, sign-in drives like Dropbox, Box and Google Drive — plus the SMB shares, Android phones and Linux disks on your own desk. All native Finder locations, no browser tabs required.
Apple Silicon & Intel · macOS 15.4 or later · Free for two cloud drives, and every share, phone and disk
Add a drive once, and it behaves like any other Finder location — browse, open, edit, and save, without a separate app or sync folder.
Cloudflare R2, Amazon S3, Backblaze B2, Wasabi, IDrive e2, MinIO, Azure Blob Storage, Alibaba Cloud OSS, Tencent Cloud COS, and Google Cloud Storage — connect with an endpoint and access key.
Dropbox, OneDrive, Google Drive, Box, pCloud and Tencent Weiyun sign in on the service's own site, through your system browser. Koofr and Nutstore (Jianguoyun) use an app password you create there.
Nextcloud, ownCloud, Seafile, OpenList/Alist, or any plain WebDAV, SFTP or FTP server — point PolyDrive at it and it shows up in Finder like any other drive. SFTP pins the server's host key the first time, and warns you if it ever changes.
Add a share from a NAS or another Mac and PolyDrive mounts it when you log in — and mounts it again whenever the network drops it. The password is checked before mounting, so a typo is a message in PolyDrive, not a system dialog.
Plug one in over USB and browse it in Finder over MTP: copy both ways, rename, delete, and play a video straight off the phone. If macOS has already claimed the device, PolyDrive works through that instead of asking you to quit anything.
Mount ext2/ext3/ext4 disk images and Raspberry Pi SD cards read-only, right from Finder — drag one onto the menu bar icon and it's browsable.
A folder of ten thousand small files takes a long time through Finder. PolyDrive moves the whole thing instead, opening as many parallel transfers as the service will take — up to about 7× faster where the service allows it, resumable if you stop it, and it works cloud to cloud too.
Right-click a file or folder and choose Keep Available Offline. It is downloaded and kept that way, so it opens on a plane or a bad hotel connection — pin a folder and everything inside it comes too. A pin badge in Finder shows what is being kept, and Stop Keeping Offline hands the space back.
Every drive appears under Finder's Locations sidebar via Apple's File Provider framework — not a virtual disk, not a sync client running in the background.
Open Spotlight, type what you are looking for, and choose Search PolyDrive to narrow the results to your mounted cloud drives — then to a single drive if you want. Every result says which drive it came from. Requires macOS 26 or later.
No backend, no PolyDrive account, no analytics. Credentials and tokens live only in your Mac's Keychain. Read the privacy policy →
Manage every connection from PolyDrive's own window, then find every drive right where Finder already puts your other locations.
PolyDrive has no accounts of its own — every drive you add is a service you already use.

PolyDrive is built on Apple's File Provider framework — the same one behind iCloud Drive. That decision is the reason everything below is true. (SMB shares are the one exception: those are mounted as volumes by macOS's own SMB client, which is also why they behave exactly like any other share on your network.)
No system extension approval, no SIP changes, no reboot. Nothing to reinstall the next time macOS updates, because there is no driver to break.
Drives appear under Finder's Locations sidebar as real folders — searchable, openable, and safe to leave connected. No virtual disk to eject.
File contents are fetched on demand in ranges. Opening a 4 GB video from a bucket doesn't download 4 GB first, and your SSD stays yours.
When you want something to stay, say so: Keep Available Offline in Finder's right-click menu downloads a file — or a whole folder — and keeps it downloaded.
There is no PolyDrive server in the path — none exists. Your Mac talks to your storage, and credentials never leave your Keychain.

Free to download, and free to keep — two cloud drives, and as many network shares, phones and local disks as you like.
Requires a Mac (Apple Silicon or Intel) running macOS 15.4 or later.
